3. Description

By default, rm does not delete directories. You can also delete each listed directory and all its contents using the-- recursive (- r or-R) option. To delete a file whose name begins with "-", such as "- foo", use one of the following commands:

Rm-foo

Rm. /-foo

Note that if you delete a file using rm, you can usually restore the contents of the file. If you want more assurance that the content is truly unrecoverable, consider using shred.

4. Examples

1) Delete files at the beginning of te

[root@localhost weijie] # ls

11.c 1.c 1.c ~ 2.c 3.c 4.c 4.c ~ 5.c 6.c te000 te001 test

[root@localhost weijie] # rm te*

Rm: do you want to delete the normal file "te000"? Y

Rm: do you want to delete the normal file "te001"? Y

Rm: cannot delete "test": it is a directory / / cannot delete a directory

2) Delete the directory

[root@localhost weijie] # rm-rf test/ forcibly delete directories

[root@localhost weijie] # ls

11.c 1.c 1.c ~ 2.c 3.c 4.c 4.c ~ 5.c 6.c
