1 00:00:00,330 --> 00:00:01,350 In this lesson, 2 00:00:01,350 --> 00:00:04,140 we're going to discuss how you can create and edit text files 3 00:00:04,140 --> 00:00:06,330 on a Linux operating system. 4 00:00:06,330 --> 00:00:08,430 As we start to perform these functions, 5 00:00:08,430 --> 00:00:10,350 we need to take a more high-level approach 6 00:00:10,350 --> 00:00:12,510 to managing the data itself. 7 00:00:12,510 --> 00:00:14,370 By managing files and directories 8 00:00:14,370 --> 00:00:16,860 you're going to be able to quickly create, retrieve, 9 00:00:16,860 --> 00:00:18,600 or otherwise process data 10 00:00:18,600 --> 00:00:20,370 so it provides you with the most benefit 11 00:00:20,370 --> 00:00:21,510 to your organizations 12 00:00:21,510 --> 00:00:24,030 and your day to day administrative tasks. 13 00:00:24,030 --> 00:00:26,370 Now, although you've made some basic file creation 14 00:00:26,370 --> 00:00:28,020 and editing tasks in the past, 15 00:00:28,020 --> 00:00:30,000 it's time for you to become more familiar 16 00:00:30,000 --> 00:00:34,320 with text based tools like Vim and GNU nano. 17 00:00:34,320 --> 00:00:36,030 Almost everything you're going to configure 18 00:00:36,030 --> 00:00:39,000 on your system is going to be done through text files. 19 00:00:39,000 --> 00:00:42,360 So now you need to make sure you have some practice creating 20 00:00:42,360 --> 00:00:44,760 and editing text files in Linux. 21 00:00:44,760 --> 00:00:47,160 Essentially, when I'm talking about a text editor 22 00:00:47,160 --> 00:00:50,250 I'm talking about an application that enables you to view, 23 00:00:50,250 --> 00:00:54,330 create, or modify the contents of different text files. 24 00:00:54,330 --> 00:00:57,060 Text editors were originally created to write programs 25 00:00:57,060 --> 00:01:00,150 in source code, but they're also used to edit 26 00:01:00,150 --> 00:01:03,030 a wide variety of text-based files. 27 00:01:03,030 --> 00:01:05,099 There are many different types of text editors 28 00:01:05,099 --> 00:01:06,600 that are compatible with Linux 29 00:01:06,600 --> 00:01:09,120 but not all of them support formatting options 30 00:01:09,120 --> 00:01:11,280 like a word processor would. 31 00:01:11,280 --> 00:01:13,680 We're going to be discussing in a lot of depth 32 00:01:13,680 --> 00:01:15,450 a couple of basic text editors 33 00:01:15,450 --> 00:01:17,100 that are compatible with Linux. 34 00:01:17,100 --> 00:01:20,580 This includes vi, Vim, Emacs, 35 00:01:20,580 --> 00:01:22,680 gVim, gedit, 36 00:01:22,680 --> 00:01:24,450 and GNU nano. 37 00:01:24,450 --> 00:01:26,850 Now Vi is a visual text editor 38 00:01:26,850 --> 00:01:28,050 and that's how it got its name. 39 00:01:28,050 --> 00:01:31,260 Vi stands for Vi from visual. 40 00:01:31,260 --> 00:01:33,270 Now this was originally created for Unix 41 00:01:33,270 --> 00:01:36,030 but was cloned into free and open source versions 42 00:01:36,030 --> 00:01:38,190 that are also run in Linux. 43 00:01:38,190 --> 00:01:42,120 Now an improved version of this is known as Vim V-I-M. 44 00:01:42,120 --> 00:01:43,890 And this is the default text editor 45 00:01:43,890 --> 00:01:46,170 in most Linux distributions. 46 00:01:46,170 --> 00:01:48,420 Another one we have is Emacs. 47 00:01:48,420 --> 00:01:52,020 Emacs is a flexible, powerful, and popular text editor 48 00:01:52,020 --> 00:01:54,690 that's used in both Unix and Linux. 49 00:01:54,690 --> 00:01:57,450 Another one we can use is gVim. 50 00:01:57,450 --> 00:02:00,090 This is a graphical version of the Vim editor. 51 00:02:00,090 --> 00:02:02,580 And it's used if you have a windowing system 52 00:02:02,580 --> 00:02:05,130 or graphical user operating system. 53 00:02:05,130 --> 00:02:08,490 If you use gedit, this is another simple, yet powerful 54 00:02:08,490 --> 00:02:10,560 GUI-based text editor that's used 55 00:02:10,560 --> 00:02:12,540 in the GNOME desktop environment. 56 00:02:12,540 --> 00:02:14,550 And if you use GNU nano, 57 00:02:14,550 --> 00:02:17,850 this is a small and user-friendly text editor. 58 00:02:17,850 --> 00:02:20,880 Now the first big one we're going to talk about is Vim. 59 00:02:20,880 --> 00:02:25,290 Vim is a contraction of Vi and improved, giving us Vim. 60 00:02:25,290 --> 00:02:28,500 Vim is an extended version of the Vi editor. 61 00:02:28,500 --> 00:02:31,320 Vim implements a text-based user interface 62 00:02:31,320 --> 00:02:33,660 and allows you to do advanced text editing, 63 00:02:33,660 --> 00:02:35,670 and it's favored by many system administrators 64 00:02:35,670 --> 00:02:38,730 and software engineers, because it is highly efficient 65 00:02:38,730 --> 00:02:42,240 and it has the ability to be extensively customized. 66 00:02:42,240 --> 00:02:45,960 Now Vim also includes useful features like text completion, 67 00:02:45,960 --> 00:02:49,650 syntax highlighting, spell checking, and much more. 68 00:02:49,650 --> 00:02:52,050 The Vim command can be called in the command line 69 00:02:52,050 --> 00:02:53,970 to bring up the Vim editor. 70 00:02:53,970 --> 00:02:56,400 When entered without a file name as an argument, 71 00:02:56,400 --> 00:02:59,880 the Vim command is going to open the welcome screen by default 72 00:02:59,880 --> 00:03:02,460 then you type Vim and the file name 73 00:03:02,460 --> 00:03:04,410 if you want to open up a file. 74 00:03:04,410 --> 00:03:06,090 If a file doesn't exist 75 00:03:06,090 --> 00:03:08,250 Vim will create the file with that name 76 00:03:08,250 --> 00:03:10,830 you specified and open it for editing. 77 00:03:10,830 --> 00:03:12,570 Vim supports multiple files 78 00:03:12,570 --> 00:03:14,910 being opened simultaneously as well. 79 00:03:14,910 --> 00:03:16,886 You can also choose to display multiple files 80 00:03:16,886 --> 00:03:19,200 horizontally or vertically. 81 00:03:19,200 --> 00:03:22,740 To do this, you'll click Control + W + V 82 00:03:22,740 --> 00:03:24,540 to create a vertical split 83 00:03:24,540 --> 00:03:28,800 or Control + W + S to split the screen horizontally. 84 00:03:28,800 --> 00:03:30,840 This allows you to have two text files open 85 00:03:30,840 --> 00:03:33,480 and you need to compare what one is versus the other, 86 00:03:33,480 --> 00:03:36,090 you can do that line by line very easily. 87 00:03:36,090 --> 00:03:38,370 Now, Vim is considered a modal editor 88 00:03:38,370 --> 00:03:40,650 and its different modes decide the functionality 89 00:03:40,650 --> 00:03:42,060 of different keys. 90 00:03:42,060 --> 00:03:44,640 The insert mode enables users to insert text 91 00:03:44,640 --> 00:03:46,620 by typing it into the system. 92 00:03:46,620 --> 00:03:49,470 The execute mode enables users to execute commands 93 00:03:49,470 --> 00:03:51,450 within the editor itself. 94 00:03:51,450 --> 00:03:53,580 The command mode enables users to perform 95 00:03:53,580 --> 00:03:56,880 different editing actions using single keystrokes, 96 00:03:56,880 --> 00:03:58,770 and our visual mode enables users 97 00:03:58,770 --> 00:04:01,410 to highlight or select text, to be able to copy it, 98 00:04:01,410 --> 00:04:03,840 delete it and do things like that. 99 00:04:03,840 --> 00:04:06,900 Now the command mode is the default mode of Vim 100 00:04:06,900 --> 00:04:08,820 but you can switch from the command mode 101 00:04:08,820 --> 00:04:11,790 to any other mode by using a single keystroke. 102 00:04:11,790 --> 00:04:15,210 If you want to go to the insert mode, simply press I 103 00:04:15,210 --> 00:04:18,420 and then you can insert text to the left of the cursor. 104 00:04:18,420 --> 00:04:21,300 If you press A, this'll switch to the insert mode 105 00:04:21,300 --> 00:04:23,610 and add text at the end of a line. 106 00:04:23,610 --> 00:04:26,730 If you press capital I, you can switch to insert mode 107 00:04:26,730 --> 00:04:29,010 and then insert text at the beginning of the line 108 00:04:29,010 --> 00:04:31,350 and press a key O to switch to insert mode 109 00:04:31,350 --> 00:04:34,560 and insert text on a new line below the cursor. 110 00:04:34,560 --> 00:04:37,620 If you press the capital O, it'll switch to insert mode 111 00:04:37,620 --> 00:04:40,227 and insert text in a new line above the cursor. 112 00:04:40,227 --> 00:04:42,420 And if you press V it'll switch you 113 00:04:42,420 --> 00:04:46,380 to visual mode to enable selection, one character at a time. 114 00:04:46,380 --> 00:04:49,590 If you press capital V you'll switch to a visual mode 115 00:04:49,590 --> 00:04:52,350 and enable selection one line at a time. 116 00:04:52,350 --> 00:04:54,210 If you press the colon key, 117 00:04:54,210 --> 00:04:55,857 this switches to the execute mode 118 00:04:55,857 --> 00:04:58,440 and enables users to enter commands. 119 00:04:58,440 --> 00:05:00,060 If you press the escape key 120 00:05:00,060 --> 00:05:02,610 you'll return back to the command mode. 121 00:05:02,610 --> 00:05:05,370 In command mode, when you enter the colon operator 122 00:05:05,370 --> 00:05:07,290 a small command prompt section will appear 123 00:05:07,290 --> 00:05:09,240 at the bottom of your editor. 124 00:05:09,240 --> 00:05:11,820 Now this indicates that you are now in execute mode 125 00:05:11,820 --> 00:05:14,640 and can run commands that are supported by Vim. 126 00:05:14,640 --> 00:05:17,820 For example, the colon W and the file name 127 00:05:17,820 --> 00:05:19,080 will actually save the file 128 00:05:19,080 --> 00:05:22,050 or write it with the file name that you're giving it. 129 00:05:22,050 --> 00:05:25,500 If you enter colon Q, this will actually quit the program 130 00:05:25,500 --> 00:05:28,830 and not save any changes that haven't been saved yet. 131 00:05:28,830 --> 00:05:31,680 If you hit colon Q with an exclamation mark 132 00:05:31,680 --> 00:05:34,950 it's going to quit while ignoring any changes that you've made. 133 00:05:34,950 --> 00:05:38,730 And if you hit colon QA, it's going to quit multiple files, 134 00:05:38,730 --> 00:05:40,530 basically quit all. 135 00:05:40,530 --> 00:05:44,340 If you do colon WQ, it's going to write the file first, 136 00:05:44,340 --> 00:05:46,050 then it's going to quit. 137 00:05:46,050 --> 00:05:49,200 If you do colon E exclamation, this is going to revert 138 00:05:49,200 --> 00:05:52,650 to the last saved format without closing the file. 139 00:05:52,650 --> 00:05:54,540 And if you do colon exclamation 140 00:05:54,540 --> 00:05:57,570 with any Linux command, that command will be executed 141 00:05:57,570 --> 00:05:59,833 and the command and the display will result 142 00:05:59,833 --> 00:06:02,580 inside of your Vim interface. 143 00:06:02,580 --> 00:06:05,940 Finally if you need help, you can type colon help, 144 00:06:05,940 --> 00:06:07,110 and the command will open up 145 00:06:07,110 --> 00:06:09,840 Vim's built-in help documentation. 146 00:06:09,840 --> 00:06:12,720 Now motions are considered single-key shortcuts. 147 00:06:12,720 --> 00:06:14,010 They're going to be used to navigate 148 00:06:14,010 --> 00:06:16,350 through the files in command mode. 149 00:06:16,350 --> 00:06:18,990 These key positions are going to move the cursor anywhere 150 00:06:18,990 --> 00:06:20,460 within a document. 151 00:06:20,460 --> 00:06:21,840 They can be used for moving the cursor 152 00:06:21,840 --> 00:06:24,330 through the characters, the words, the lines, 153 00:06:24,330 --> 00:06:26,640 or even huge blocks of text. 154 00:06:26,640 --> 00:06:28,140 By pressing the H key, 155 00:06:28,140 --> 00:06:30,330 you're going to move left one character. 156 00:06:30,330 --> 00:06:33,660 If you press the J key, you'll move down one line. 157 00:06:33,660 --> 00:06:36,690 If you press the K key, you'll move up one line. 158 00:06:36,690 --> 00:06:38,040 And if you press the L key 159 00:06:38,040 --> 00:06:40,230 you'll move to the right one character. 160 00:06:40,230 --> 00:06:42,240 If you want to go to the beginning of the line, 161 00:06:42,240 --> 00:06:44,730 use the Shift and the six key giving you 162 00:06:44,730 --> 00:06:47,430 that upwards caret that brings you to the beginning 163 00:06:47,430 --> 00:06:48,690 of the current line. 164 00:06:48,690 --> 00:06:50,910 If you want to go to the end of the current line, 165 00:06:50,910 --> 00:06:52,890 put the dollar sign in. 166 00:06:52,890 --> 00:06:56,070 If you want to move to the next word, press the W key. 167 00:06:56,070 --> 00:06:59,310 If you want to go back a word, press the B key. 168 00:06:59,310 --> 00:07:01,410 If you want to move to the end of the current word 169 00:07:01,410 --> 00:07:02,970 or to the end of the next word, 170 00:07:02,970 --> 00:07:04,650 if you're already at the end of your word, 171 00:07:04,650 --> 00:07:06,960 just press E for end. 172 00:07:06,960 --> 00:07:09,930 If you press Shift + L this'll move the cursor 173 00:07:09,930 --> 00:07:11,610 to the bottom of your screen. 174 00:07:11,610 --> 00:07:14,100 And if you use Shift + H it's going to move the cursor 175 00:07:14,100 --> 00:07:16,440 to the first line of your screen. 176 00:07:16,440 --> 00:07:20,160 If you press line number and Shift + G you'll move directly 177 00:07:20,160 --> 00:07:22,140 to that specified line number. 178 00:07:22,140 --> 00:07:24,480 If you press GG, you'll move the cursor 179 00:07:24,480 --> 00:07:26,610 to the first line of the file. 180 00:07:26,610 --> 00:07:28,770 If you press Shift + G by itself 181 00:07:28,770 --> 00:07:32,070 it'll move the cursor to the last line of the file. 182 00:07:32,070 --> 00:07:35,160 Now, in addition to using the H, J, K, and L keys 183 00:07:35,160 --> 00:07:37,440 to move side to side or up and down, 184 00:07:37,440 --> 00:07:40,830 you can also use the up, down, left, and right arrow keys. 185 00:07:40,830 --> 00:07:43,350 You also can use conventional navigation keys 186 00:07:43,350 --> 00:07:48,300 like Home and Page Up and Page Down inside of Vim. 187 00:07:48,300 --> 00:07:51,240 When you're doing editing operations in command mode, 188 00:07:51,240 --> 00:07:53,730 this is really some powerful things you can do 189 00:07:53,730 --> 00:07:56,610 to manipulate the text with really simple keystrokes. 190 00:07:56,610 --> 00:07:59,070 And it really shows the power of Vim. 191 00:07:59,070 --> 00:08:01,050 You can also use these things in combination 192 00:08:01,050 --> 00:08:04,560 with other motions to edit multiple characters at once. 193 00:08:04,560 --> 00:08:07,290 The X operator is going to delete the character selected 194 00:08:07,290 --> 00:08:10,860 by the cursor, where D is going to delete the text. 195 00:08:10,860 --> 00:08:13,890 DD will delete the entire current line. 196 00:08:13,890 --> 00:08:17,190 P will paste the text on the line below the cursor. 197 00:08:17,190 --> 00:08:19,530 Capital P will paste the text on the line 198 00:08:19,530 --> 00:08:21,630 directly above the cursor. 199 00:08:21,630 --> 00:08:24,240 The forward slash with a text string will search 200 00:08:24,240 --> 00:08:26,547 the document for that specific text. 201 00:08:26,547 --> 00:08:28,560 And a question mark with the text string 202 00:08:28,560 --> 00:08:30,570 will search backwards through the document 203 00:08:30,570 --> 00:08:32,669 for specific text as well. 204 00:08:32,669 --> 00:08:35,280 If you press Y that'll copy the text, 205 00:08:35,280 --> 00:08:39,240 and YY will copy the line directly above the cursor. 206 00:08:39,240 --> 00:08:42,780 If you type C, a range of lines, and another C, 207 00:08:42,780 --> 00:08:45,750 it's going to begin a change in the specific range, 208 00:08:45,750 --> 00:08:48,600 and U will undo your latest change. 209 00:08:48,600 --> 00:08:52,260 Capital U undoes all changes in your current line, 210 00:08:52,260 --> 00:08:54,810 and capital ZZ will write the file 211 00:08:54,810 --> 00:08:56,370 only if changes were made, 212 00:08:56,370 --> 00:08:58,950 and then it'll quit the Vim editor. 213 00:08:58,950 --> 00:09:00,990 Now a count is a number that multiplies 214 00:09:00,990 --> 00:09:03,480 the effects of keystrokes within Vim. 215 00:09:03,480 --> 00:09:05,670 It can be used in combination with motions, 216 00:09:05,670 --> 00:09:07,380 operators, or both. 217 00:09:07,380 --> 00:09:10,290 When used with a motion, cursor movement is multiplied 218 00:09:10,290 --> 00:09:12,720 according to the count specified. 219 00:09:12,720 --> 00:09:15,570 When using editing operations, the action gets repeated 220 00:09:15,570 --> 00:09:17,730 the number of times specified. 221 00:09:17,730 --> 00:09:19,980 Now another user-friendly text editor 222 00:09:19,980 --> 00:09:22,080 that evolved from the Pico text editor 223 00:09:22,080 --> 00:09:25,170 that was created for Unix-like systems is nano, 224 00:09:25,170 --> 00:09:27,930 also known as GNU nano. 225 00:09:27,930 --> 00:09:30,000 While Vim is a powerful text editor, 226 00:09:30,000 --> 00:09:32,100 it is not really the most user-friendly 227 00:09:32,100 --> 00:09:34,860 as evidenced by its multiple modes, its bare interface, 228 00:09:34,860 --> 00:09:37,890 and all those key stroke commands that I just listed. 229 00:09:37,890 --> 00:09:40,320 Know those are really that intuitive. 230 00:09:40,320 --> 00:09:42,690 Now on the other hand, the nano editor 231 00:09:42,690 --> 00:09:45,270 is much more visually helpful in that it displays 232 00:09:45,270 --> 00:09:48,540 its command shortcuts at the bottom of every open file. 233 00:09:48,540 --> 00:09:50,400 It also doesn't have different modes 234 00:09:50,400 --> 00:09:52,020 that you need to switch between. 235 00:09:52,020 --> 00:09:54,780 Despite these advantages though, nano does lack 236 00:09:54,780 --> 00:09:57,240 many of the features that makes Vim so powerful, 237 00:09:57,240 --> 00:10:00,570 like the split screen, text completion, syntax coloring, 238 00:10:00,570 --> 00:10:02,280 and some other features. 239 00:10:02,280 --> 00:10:04,110 The nano command can be called 240 00:10:04,110 --> 00:10:06,660 if you'd want to use it by just typing in nano 241 00:10:06,660 --> 00:10:08,190 at the command prompt. 242 00:10:08,190 --> 00:10:11,340 Automatically the command will open a new file for editing 243 00:10:11,340 --> 00:10:14,550 and you can later save this file with a specific name. 244 00:10:14,550 --> 00:10:16,920 You can also type nano and the file name 245 00:10:16,920 --> 00:10:19,560 if you want to open an existing file. 246 00:10:19,560 --> 00:10:22,530 If the file doesn't exist, nano will create that file 247 00:10:22,530 --> 00:10:24,120 using the name you just specified 248 00:10:24,120 --> 00:10:26,490 and open a blank file for you to edit. 249 00:10:26,490 --> 00:10:28,950 Like Vim, nano supports multiple files 250 00:10:28,950 --> 00:10:31,110 being open simultaneously. 251 00:10:31,110 --> 00:10:33,450 In GNU nano the functions you use 252 00:10:33,450 --> 00:10:35,550 will work with text editors and the editor itself 253 00:10:35,550 --> 00:10:37,740 are going to be referred to as shortcuts. 254 00:10:37,740 --> 00:10:39,840 Most of these are going to be activated by pressing 255 00:10:39,840 --> 00:10:42,000 the Control key, which is represented 256 00:10:42,000 --> 00:10:45,390 by the upper caret symbol or the Shift + six key 257 00:10:45,390 --> 00:10:46,680 inside the editor. 258 00:10:46,680 --> 00:10:48,750 Then you're going to press the key that corresponds 259 00:10:48,750 --> 00:10:50,940 to the function you're trying to perform. 260 00:10:50,940 --> 00:10:54,390 For example if I saw the upward caret G 261 00:10:54,390 --> 00:10:57,360 that would actually be used as a Control + G shortcut 262 00:10:57,360 --> 00:10:59,790 and it's used to open the nano help screen. 263 00:10:59,790 --> 00:11:02,520 If I use Control + X that's going to exit nano 264 00:11:02,520 --> 00:11:04,260 and close the current buffer. 265 00:11:04,260 --> 00:11:07,740 If I use Control + O it's going to save the currently open file 266 00:11:07,740 --> 00:11:09,660 or it's going to save the output. 267 00:11:09,660 --> 00:11:11,370 Control + J is going to be used 268 00:11:11,370 --> 00:11:13,590 to justify the current paragraph. 269 00:11:13,590 --> 00:11:16,140 Control + R is used to insert another file 270 00:11:16,140 --> 00:11:18,600 into the current one at that position. 271 00:11:18,600 --> 00:11:21,420 Control + W is used to search the file. 272 00:11:21,420 --> 00:11:24,810 Control + K is used to cut the currently selected line. 273 00:11:24,810 --> 00:11:28,320 Control + U is used to paste that line that you just cut. 274 00:11:28,320 --> 00:11:30,420 Control + C is going to be used to display 275 00:11:30,420 --> 00:11:32,190 the cursor's position. 276 00:11:32,190 --> 00:11:33,690 Like other text editors, 277 00:11:33,690 --> 00:11:36,270 you can navigate nano using your arrow keys, 278 00:11:36,270 --> 00:11:39,300 your Page Up, Page Down, Home and End keys, 279 00:11:39,300 --> 00:11:40,980 and other things like that. 280 00:11:40,980 --> 00:11:42,630 If you're missing any of these keys, 281 00:11:42,630 --> 00:11:44,610 nano also provides shortcuts for those, 282 00:11:44,610 --> 00:11:46,860 such as Control + V to go to the next page, 283 00:11:46,860 --> 00:11:50,010 or Control + Y to go back a previous page. 284 00:11:50,010 --> 00:11:52,740 Copying parts of the text on a line also requires you 285 00:11:52,740 --> 00:11:55,140 to mark that text that you want to copy, 286 00:11:55,140 --> 00:11:57,060 and you do that by using the Control 287 00:11:57,060 --> 00:11:59,100 and the upper caret symbol. 288 00:11:59,100 --> 00:12:01,020 Then you're going to navigate your cursor 289 00:12:01,020 --> 00:12:02,880 to highlight the text you want to copy 290 00:12:02,880 --> 00:12:05,730 and press Alt and that upper caret symbol. 291 00:12:05,730 --> 00:12:07,950 This will mark or highlight that text, 292 00:12:07,950 --> 00:12:10,500 and then you can use Control + U to paste it 293 00:12:10,500 --> 00:12:12,390 into another location. 294 00:12:12,390 --> 00:12:15,060 Another program we can use is gedit. 295 00:12:15,060 --> 00:12:18,180 Gedit is a text editor that is the default text editor 296 00:12:18,180 --> 00:12:20,250 inside the GNOME desktop environment 297 00:12:20,250 --> 00:12:22,440 which is a graphical user interface. 298 00:12:22,440 --> 00:12:25,020 And it's a member of the GNU project. 299 00:12:25,020 --> 00:12:29,490 Unlike Vim and nano, gedit uses a graphical user interface. 300 00:12:29,490 --> 00:12:31,620 And it has a typical menu-based design 301 00:12:31,620 --> 00:12:33,720 that makes it really easy to work with. 302 00:12:33,720 --> 00:12:37,530 If you use notepad in Windows or text edit in a Mac, 303 00:12:37,530 --> 00:12:38,610 you're probably pretty familiar 304 00:12:38,610 --> 00:12:40,680 with using something like gedit. 305 00:12:40,680 --> 00:12:43,170 It also has features like syntax highlighting 306 00:12:43,170 --> 00:12:45,180 and spell checking and it can be customized 307 00:12:45,180 --> 00:12:46,740 through different plugins. 308 00:12:46,740 --> 00:12:49,050 Although you can launch gedit from the desktop, 309 00:12:49,050 --> 00:12:51,360 you can also launch it from the command line interface 310 00:12:51,360 --> 00:12:53,040 using the gedit command. 311 00:12:53,040 --> 00:12:55,620 But again, you have to have a graphical user interface 312 00:12:55,620 --> 00:12:57,120 installed on your Linux system 313 00:12:57,120 --> 00:12:58,473 if you want to use gedit.
