Therefore, especially when using the rm command to delete When cataloging, be cautious.

If the rm command does not add any options, the default execution is rm -i file name, that is, it will ask whether to delete a file before deleting it. For example:

[root@localhost ~]# touch cangls [root@localhost ~]# rm cangls rm: delete plain empty file "cangls"?y #Will ask whether to delete before deleting

If there are tens of thousands of subdirectories or subfiles in the directory to be deleted, then ordinary rm deletion requires at least tens of thousands of confirmations. Therefore, when we actually delete files, we will choose to force delete. For example:

[root@localhost ~]# mkdir -p /test/lm/movie/jp # Recreate the test directory [root@localhost ~]# rm -rf /test #Force Delete
