Linux RM Command

The RM command in Linux is to delete files and directories. When using the-r parameter, it is important to note that the directory and files will be deleted.

1 . Command format:

RM [ Options ] file ...

2 . Command function:

Delete one or more files or directories in a directory, and RM does not delete the directory if the-r option is not used . If you use rm to delete a file, you can usually still restore the file to its original state.

3 . Command parameters:

-F,--force mandatory meaning, ignoring nonexistent files, never give hints.

-I,--interactive for interactive deletion

-R,-R,--recursive instructs rm to delete all directories and subdirectories listed in the parameters recursively.

-V,--verbose detailed display of the steps performed

--help Display this help message and exit

--version output version information and exit

command example:

1. -i parameter, ask before deleting

[Email protected] ~]# cd/tmp[[email protected] tmp]# rm-i bashrcrm:remove regular file ' BASHRC '? Y add-i parameter, delete will be actively asked to avoid the deletion of the wrong file [[email protected] tmp]# rm-i bashrc* use wildcards, the TMP under the BASHRC start to delete all Rm:remove Regu Lar file ' Bashrc_hlink '? Yrm:remove Symbolic link ' bashrc_slink '? Yrm:remove regular file ' Bashrc_slink_1 '? Yrm:remove Symbolic link ' bashrc_slink_2 '? Y

2. -R parameter, recursively delete directory

[[email protected] tmp]# rmdir/tmp/etcrmdir:failed to remove '/tmp/etc ': Directory not empty cannot be deleted because the catalog is not empty [[email PR Otected] tmp]# rm-r/tmp/etcrm:descend into directory '/tmp/etc '? ^c Press Y to confirm, press CTRL + C to exit

Because the identity is root, the default has been added to the-I option, so you have to press Y to delete!

If you do not want to continue pressing Y, you can press [CTRL]-C] to end the work of RM.

This is a protective action, if you are sure you want to delete this directory without asking, you can do this:

[Email protected] tmp]#/rm-r/tmp/etc

Precede the command with a backslash to ignore the specified option for alias

3. -F parameter, force delete, System not prompt

[Email protected] tmp]# rm-f Test.log

4. Custom Recycle Bin function

[[email protected] tmp]# myrm () { D=/tmp/$ (date  +%y%m%d%h%m%s); mkdir -p  $D; mv  "[email protected]"   $D  &&  echo  "moved to  $D  ok";  }[[email protected] tmp]# alias rm= ' Myrm ' [[email protected] tmp]# touch 1.log 2.log 3.log[[email protected]  tmp]# lltotal 0-rw-r--r-- 1 root root 0 apr  7 14:19  1.log-rw-r--r-- 1 root root 0 apr  7 14:19 2.log-rw-r--r--  1 root root 0 apr  7 14:19 3.log[[email protected] tmp ]# rm [123].logmoved to /tmp/20160407142017 ok[[email protected] tmp]#  ls /tmp/20160407142017/1.log  2.log  3.log[[email protected] tmp]#

[[email protected] tmp]# touch./-bbb-[[email protected] tmp]# ls-ltotal 0-rw-r--r--1 root root 0 Apr 7 14:26-bbb-[[em AIL protected] tmp]# rm-bbb-mv:invalid option--'-' Try ' mv--help ' for more information. [Email protected] tmp]# rm./-bbb-moved to/tmp/20160407142651 Ok[[email protected] tmp]#
