2 root root 4.0K Apr 14 03:16 folderAĭrwxr-xr-x. The following example uses mkdir to create the new directories, folderA, folderB, and folderC: testdir]# mkdir folderA folderB testdir]# ls -lahĭrwxr-xr-x. You can also use the mkdir command to create multiple directories with a single command. 1 root root 21 Apr 14 01:58 testdir]# mkdir testdir]# mkdir testdir]# ls -lahĭrwxr-xr-x. The following example uses mkdir to create the new directories, folder1 and folder2: testdir]# ls -lahĭrwxr-xr-x. testdir]# cat testdir]# cat testdir]# cat change.txt > testdir]# cat edit.txt The > command prevents a complete rewrite of edit.txt. The following example uses > to add the contents of change.txt to the end of the file, edit.txt. If the file already exists, > appends the new contents to the end of the file. If no file exists, > creates the file and adds the contents. However, you can use two redirect symbols, >, to append content to the end of a file. If you rewrite critical files, this can cause catastrophic issues. Note: As previously mentioned, the redirect symbol can rewrite, as shown in the preceding example, with no option to recover lost data. The following example demonstrates how you can accidentally rewrite the contents of the existing file, Important: testdir]# cat ImportantĭON'T DELETE THIS testdir]# > testdir]# cat testdir]# 1 root root 21 Apr 14 01:58 testdir]# > testdir]# ls -lahĭrwxr-xr-x. The following example uses > to create the new file, example.txt: testdir]# ls -lahĭrwxr-xr-x. You cannot recover the previous contents. The standard redirect symbol, >, creates a single new file without any content or replaces an existing file with an empty file of the same name.ĬAUTION: You should use the redirect symbol with care because you can accidentally overwrite existing files. 1 root root 0 Apr 14 01:57 testdir]# cat > test.txt The following example uses cat > followed by the content to create the new file, test.txt, with one line of content: testdir]# ls -lahĭrwxr-xr-x. The cat > command creates a non-empty file by entering the contents after the greater-than sign.
1 root root 0 Apr 14 01:50 testdir]# touch sample1 sample2 testdir]# ls -lahĭrwxr-xr-x. The following example uses the touch command to create the new files, sample1, sample2, and sample3: testdir]# ls -lah
You can also use the touch command to create multiple files with a single command. 8 root root 4.0K Apr 14 01:47 testdir]# touch testdir]# touch testdir]# ls -lahĭrwxr-xr-x. The following example uses the touch command to create the new files, demo and sample.txt: testdir]# ls -lahĭrwxr-xr-x. You can create files by using the following commands:
#ICOPY EDIT FILE HOW TO#
The following example shows how to view the contents of the Important file with the cat command: testdir]# cat Important The cat command displays the contents of a file. Directories are shown with a line starting with d. ls returns no files, while ls -lah returns hidden files and directories. The following example shows the listing of an empty directory. They include a listing of all files (including hidden files) in a human-readable, long-list view. ls command options, such as ls -lah, provide additional information. You can use the ls command to show the contents of a directory. To view the contents of a file, use the cat command. To view the files in a directory, use the ls command.
