rm command in Linux with examples
Example 1: Check rm linux command version
You can check rm command version by using
--version option as shown below. As you can check from below output, current version is
[root@localhost ~]# rm --version rm (GNU coreutils) 8.22 Copyright (C) 2013 Free Software Foundation, Inc. License GPLv3+: GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html>.

--version : output version information and exit
Example 2: Remove a File Using rm command
You can simply remove a file
download.txt by using rm command as shown below. Please note that by default it will ask you for confirmation before removing the file.
[root@localhost ~]# rm download.txt rm: remove regular file ‘download.txt’? y
Example 3: Using rm options -i to interactively delete file
You can use rm flag
-i to interactively delete the file as shown below. By default this option will be enabled.
[root@localhost ~]# rm -i file.txt rm: remove regular file ‘file.txt’? y
-i : prompt before every removal
Example 4: Using rm options -f to delete a file without confirmation
If you do not want rm command to ask for a confirmation before deleting a file you can use
-f option to forcefully delete it as shown below.
[root@localhost ~]# rm -f file.txt
-f : ignore nonexistent files and arguments, never prompt
Example 5: Using rm command option -v to verbose the output
If you want to see the output of rm command then you need to use
-v option to show the output as mentioned in below example.
[root@localhost ~]# rm -v file1.txt rm: remove regular empty file ‘file1.txt’? y removed ‘file1.txt’
-v : explain what is being done
Example 6: Remove an empty directory without using rm command -d flag
You can simply delete empty directory by using
rm -rvf hello command as shown below.
[root@localhost ~]# rm -rvf hello removed directory: ‘hello’
-r : remove directories and their contents recursively
Example 7: Using rm options -r in Linux to delete files recursively along with directory
If you want to recursively delete all the files and directory along with its sub-directories then you need to use
-r flag with rm command as shown below.
[root@localhost ~]# rm -rvf example removed ‘example/file.txt’ removed ‘example/file2.txt’ removed directory: ‘example’
Example 8: Using rm command in Linux to remove everything from current directory
You can also use wildcard(*) character to delete all the files and directories. In this example, we are trying to delete all files and sub directories from hello directory as shown below.
[root@localhost hello]# rm -vf * removed ‘file1.txt’ removed ‘file2.txt’ removed ‘file.txt’
Example 9 : Remove Empty Directories
If you want to remove empty directories then you need to use
-d flag with rm command in Linux as shown below.
[root@localhost ~]# rm -vd hello rm: remove directory ‘hello’? y removed directory: ‘hello’
-d : Remove empty directories
If directory is not empty then it will throw below error.
[root@localhost ~]# rm -vd hello rm: cannot remove ‘hello’: Directory not empty
Example 10 : Preserve root file system
If you do not want to recursively delete everything from root(/) filesystem then you need to use
--preserve-root option as shown below.
[root@localhost ~]# rm -rf --preserve-root /
By default it will run with
[root@localhost ~]# rm -rf / rm: it is dangerous to operate recursively on ‘/’ rm: use --no-preserve-root to override this failsafe
--preserve-root : do not remove ‘/’
Example 11 : Do not preserve root filesystem
If you want to recursively delete everything from root(/) filesystem then you need to use
--no-preserve-root option with rm command as shown below.
[root@localhost ~]# rm -rf --no-preserve-root /
--no-preserve-root : do not treat ‘/’ specially
Example 12. Check Other Options with –help
You can check all the other rm options that can be used using
--help flag as shown below.
[root@localhost ~]# rm --help Usage: rm [OPTION]... FILE... Remove (unlink) the FILE(s). -f, --force ignore nonexistent files and arguments, never prompt -i prompt before every removal -I prompt once before removing more than three files, or when removing recursively; less intrusive than -i, while still giving protection against most mistakes --interactive[=WHEN] prompt according to WHEN: never, once (-I), or always (-i); without WHEN, prompt always --one-file-system when removing a hierarchy recursively, skip any directory that is on a file system different from that of the corresponding command line argument --no-preserve-root do not treat '/' specially --preserve-root do not remove '/' (default) -r, -R, --recursive remove directories and their contents recursively -d, --dir remove empty directories -v, --verbose explain what is being done --help display this help and exit --version output version information and exit By default, rm does not remove directories. Use the --recursive (-r or -R) option to remove each listed directory, too, along with all of its contents. To remove a file whose name starts with a '-', for example '-foo', use one of these commands: rm -- -foo rm ./-foo Note that if you use rm to remove a file, it might be possible to recover some of its contents, given sufficient expertise and/or time. For greater assurance that the contents are truly unrecoverable, consider using shred.
