UNIX for Dummies Questions & Answers

Hi,

My first time on this site, please excuse me if I've come to the wrong forum. I'm fairly new to Unix/Linux and hoping you can help me out.

I'm looking for a command line that will return a list of directories that are larger than 50M and older than 2 days.

I thought it may be something a simple as:

Code:

find /wlwork/epc_domain/stage/  -name 'job*' -type d -mtime +2 -size +50M

But that doesn't seem to work.

I had created 2 directories that are larger than 50M so it should have returned something.


I tried

Code:

du -sm /wlwork/epc_domain/stage/job* | awk '$1 > 50'

it returns directories that are larger than 50MB but I need to be able to delete the directories that are older than 2 days from this result.



Any suggestions?

TIA

Perhaps because the names of those 2 dirs dont start with "job"...

I wish it were that easy.

There are several directories that begin with job in that path

One way of doing this is using stat command:

Code:

du -sm /wlwork/epc_domain/stage/job* | while read size dir
do
        d_epoch=$( stat --printf=%Y "$dir" )
        c_epoch=$( date +%s )

        (( diff = ( c_epoch - d_epoch ) / 86400 ))

        if [ $diff -gt 2 ] && [ $size -gt 50 ]
        then
                echo "Deleting dir: $dir"
                # Delete here
        fi
done

If you created those 2 dirs. just now then it wont return anything due to the "-mtime +2" criterion...

A directory is a file that contains several entries where each entry is an inode number and a name. Is is possible that a directory will get to be 50 MB but that would be a lot of entries. You probably mean the sum of the sizes of all the files and subdirectories in a directory. That is a different concept and has little to do with the size of the directory itself.

Thanks for the replies.

Yes I meant the sum of all files and sub-directories in the directory.

We have instances where some of the directories (total sum) are very large due to logging etc. So to keep it clean, I was tasked with setting up a cron to clean up directories based on condition.

I'll keep plugging away
