This article mainly explains "how to use the rm command of Linux correctly", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let Xiaobian take you to learn "how to use Linux rm command correctly"!

rm is a dangerous command and should be used with great care, especially for beginners, or the entire system will be destroyed by this command (e.g. rm * -rf in/(root directory)). So, before we execute rm, it's best to confirm which directory and what to delete, and keep a high level of clarity when doing so.

1. Command Format:

rm [options] file…

2. Command function:

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

3. Command Parameters:

-f, --force Ignore files that don't exist and never give a hint.

-i, --interactive for interactive deletion

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

-v, --verbose Show steps in detail

--help Display this help message and exit

--version Output version information and exit

4. Command example:

Example 1: Delete file, the system will first ask whether to delete.

Command:

rm file name

Output:

The copy code is as follows:

[root@localhost test1]# ll

total of 4

The copy code is as follows:

-rw-r--r-- 1 root root 56 10-26 14:31 log.log

root@localhost test1]# rm log.log

rm: Do you want to delete the general file "log.log"? y

The copy code is as follows:

root@localhost test1]# ll

Total 0[root@localhost test1]#

Description:

After entering the rmlog.log command, the system will ask if you want to delete it. After entering y, the file will be deleted. If you don't want to delete it, the data n.

Example 2: forcibly delete file, the system will no longer prompt.

Command:

The copy code is as follows:

rm -f log1.log

Output:

The copy code is as follows:

[root@localhost test1]# ll

total of 4

The copy code is as follows:

-rw-r--r-- 1 root root 23 10-26 14:40 log1.log

[root@localhost test1]# rm -f log1.log

[root@localhost test1]# ll

Total 0[root@localhost test1]#

Example 3: Delete any.log file; ask for confirmation one by one before deleting

Command:

rm -i *.log

Output:

The copy code is as follows:

[root@localhost test1]# ll

total of 8

The copy code is as follows:

-rw-r--r-- 1 root root 11 10-26 14:45 log1.log

-rw-r--r-- 1 root root 24 10-26 14:45 log2.log

[root@localhost test1]# rm -i *.log

rm: Do you want to delete the generic file "log1.log"? y

rm: Do you want to delete the generic file "log2.log"? y

[root@localhost test1]# ll

Total 0[root@localhost test1]#

Example 4: Delete the test1 subdirectory and all files in the subdirectory

Command:

The copy code is as follows:

rm -r test1

Output:

The copy code is as follows:

[root@localhost test]# ll

Total 24drwxr-xr-x 7 root root 4096 10-25 18:07 scf

drwxr-xr-x 3 root root 4096 10-25 17:56 test5

[root@localhost test]# rm -r test1

rm: Enter directory "test1"? y

rm: Delete the generic file "test1/log3.log"? y

rm: Delete directory "test1"? y

The copy code is as follows:

[root@localhost test]# ll

Example 5: The rm -rf test2 command deletes the test2 subdirectory and all files in the subdirectory without confirming them one by one.

Command:

The copy code is as follows:

rm -rf test2

Output:

The copy code is as follows:

[root@localhost test]# rm -rf test2

[root@localhost test]# ll

Example 6: Delete files starting with-f

Command:

rm -- -f

Output:

The copy code is as follows:

[root@localhost test]# touch -- -f

[root@localhost test]# ls -- -f

-f[root@localhost test]# rm -- -f

rm: Delete the general empty file "-f"? y

The copy code is as follows:

[root@localhost test]# ls -- -f

ls: -f: No such file or directory

You can also use the following steps:

The copy code is as follows:

[root@localhost test]# touch ./- f

[root@localhost test]# ls ./- f

./- f[root@localhost test]# rm ./- f

rm: Delete general empty file "./- f"? y

The copy code is as follows:

[root@localhost test]#

Example 7: Custom Recycle Bin Function

Command:

The copy code is as follows:

myrm(){ d=/tmp/$(date +%y%m%d%h%m%s); mkdir -p $d; mv "$@" $d && echo "moved to $d ok"; }

Output:

The copy code is as follows:

[root@localhost test]# myrm(){ d=/tmp/$(date +%y%m%d%h%m%s); mkdir -p $d; mv "$@" $d && echo "moved to $d ok"; }

[root@localhost test]# alias rm='myrm'

[root@localhost test]# touch .log .log .log

[root@localhost test]# ll
