find command...

Hazem Mahmoud_3 — Fri, 07 May 2004 10:02:12 GMT

I'm having a little trouble getting find to do what I want it to. Here is the deal:
I have a directory that has a bunch of directories. I want to remove all directories inside that directory that are older than 90 days, using the timestamp of that directory. Example:
# ll /maindir
drwxrwsr-x 4 speclive live 8192 Aug 17 2003 dir1
drwxrwsr-x 4 spxlive live 8192 May 7 09:32 dir2
drwxrwsr-x 4 spxlive live 8192 May 3 05:33 dir3
drwxrwsr-x 2 spxlive live 96 Jan 24 14:59 dir4

Therefore I would want dir1 and dir4 deleted, with all the contents under them.
Also, I would first want to list which directories I selected, then remove them (these can be in two different find commands). Here is what I have so far, but it's working right:
find /maindir -name * +mtime +90 -exec ll {} \;
find /maindir -name * +mtime +90 -exec rm {} \;

I've also tried playing with -prune, but it doesn't do what I want.
10 points to the person who can help me solve this! Thanks!

I think you're close but you need to specify the directory option:

find /maindir -type d -name * +mtime +90 -exec ll {} \;

find /maindir -type d -name * +mtime +90 -exec rm {} \;

You should add the "-type d" option to your find to select only directories. You could also remove "-name *" for 2 reasons :

1. * is evaluated by your shell when launching so it will only find dirs that are in your start dir ".". You should put
-name "*" instead so that * is evaluated each time

2. -name "*" is what is done by default if you don't put -name.

So your command could be :
find /maindir -type d +mtime +90 -exec ll {} \;

yes, the "-type d" is what you want, but
to list the acutal directories found do:

use: "-exec ls -ld {} \;"

I tried it with type -d and here is the message I got:
find: missing conjunction

I also tried it without the -name option.

Another point :

using "ll {}\;" will list the content of each directory found. you should use -d option to see the directory itself.

So it will look :
find /maindir -type d +mtime +90 -exec ll -d {} \;

I didn't saw the +mtime... use -mtime instead.

Ok, we're getting closer, but not there yet. Here is what I used:
find /maindir -type d -mtime +90 -exec ll -d {} \;

Good catch on the -mtime Fred, that was one of my problems. Also, it did not like it when I specified -name *, so another good catch on that one Fred.
However, it is giving me all directories under /maindir, including the sub-directores under the directories in /maindir. So it is still recursively going down the directory structure. It is however giving me the directores older than 90 days that are directly under /maindir.
Any ideas how to stop it from going further down the directory structure?

Another answer again (I'm a bit tired) :

about the concept this time. It's not because your dir has a modification date older than 90 days that all of its subdirs will be older than 90 days.

Once you'll run the find with ll, take the answers, and do the same find with "-mtime -90" on them...

Re: find command...

Fred Ruffet — Fri, 07 May 2004 10:32:55 GMT

for your recursive problem, it's time to use -prune. Each matching dir will be skipped.

When I use -prune it does not pick up anything.

Difference with or whitout -prune :

#find /etc -type d -mtime +90 -prune -exec ls -ld {} \; | wc -l
24
#find /etc -type d -mtime +90 -exec ls -ld {} \; | wc -l
187

That did it Fred!!! I had prune running before the -mtime and it seems like it did not like that (I'm not sure why). So I had it run after the -mtime and it worked great! Thanks for all your help troubleshooting this!!!

Re: find command...

Geoff Wild — Fri, 07 May 2004 11:42:35 GMT

Fred is correct:

# find /etc -type d -mtime +90 -exec ls -d {} \; |wc
175 175 4468
# find /etc -type d -mtime +90 -prune -exec ls -d {} \; |wc
46 46 680

Now - as far as rm, it won't delete directory's if they have contents - unless you do a rm -rf and that is dangerous!

I would be more inclined to find all dirs over 90 days, list their contents, then delete the files under them - just to be safe....

Thanks for the information Geoff, I'll definitely take that into consideration.

Congratulations on your new hat Fred!!! I hope your first hat feels good!:)
