Linux rm command

Linux Command Encyclopedia

Linux rm (full English spelling: remove) command is used to delete a file or a directory.

Syntax

rm [options] name...

Parameters：

• -i Ask for confirmation one by one before deletion.
• -f Even if the original file attribute is set to read-only, delete it directly without confirmation.
• -r Delete the directory and all files under it recursively.

Examples

To delete a file, you can directly use the rm command; if you delete a directory, you must use the "-r" option, for example:

# rm  test.txt 
rm：是否删除 一般文件 "test.txt"? y  
# rm  homework  
rm: 无法删除目录"homework": 是一个目录  
# rm  -r  homework  
rm：是否删除 目录 "homework"? y 

To delete all files and directories under the current directory, the command line is:

rm  -r  * 

Once a file is deleted by the rm command, it cannot be recovered, so you must be especially careful when using this command.
