Requirements: delete files, directory structure is: ip/ year / month, everyone has a directory that now needs to delete all files before 2012, and delete specific months after 2012.

I originally wanted to use find, but I found that these files time (a _ dint _ m _ c) records were no longer generated at the beginning.

Have no choice but to think of a local way to traverse, who has a good way, welcome to let me know.

The code is as follows:

#! / bin/bash

Cd / home/wanggy/rmfile/

Ls-l | grep ^ d | awk'{print $NF}'> / home/wanggy/tmp

Cat / home/wanggy/tmp | while read dir1

Do

Cd $dir1

Echo "first level directory $dir1"

Ls-l | grep ^ d | awk'{print $NF}'> / home/wanggy/tmp1

Cat / home/wanggy/tmp1 | while read dir2

Do

Echo "second level directory $dir2"

Cd $dir2

# rejudge the directories that are greater than 2012, and delete them directly if they are less than 2012.

If [$dir2-gt 2011]; then

Ls-l | grep ^ d | awk'{print $NF}'> / home/wanggy/tmp2

Cat / home/wanggy/tmp2 | while read dir3

Do

# deletions before September "

If [$dir3-lt 09]; then

Rm-rf $dir3

Fi

Done

Else

Echo "Delete directories before 2012: $dir2"

Rm-rf $dir2

Fi

# return to the previous level

Cd..

Done

# return to the previous level

Cd..

Done
