listing directories larger than specified size?

zefyr · 03-27-2008, 10:33 AM

Hello,

I would like to filter out all directories below a specific directory larger than 1GB. Like list all the Users home directories that are larger than 1GB. I'm experimenting with du -sk in combination with grep but I just can't seem to figure out how to do this. Im quite new to linux so bare with me.

Anyone has any thoughts on how to do this? Any help will be appreciated!

Regards,

Zefyr

You can use du in conjunction with gawk, e.g.

Code:

du -ks /home/*/ | gawk '$1 > 1000000 {print $2}'

Works like a charm, thank you!

While I'm at it, would you (or anyone for that matter) happen to know how to schedule this so that it runs every day at a specific time? That is if I put it in a script.

Thanks again!

You may have a look at

Code:

man crontab     # describes the crontab command
man 5 crontab   # decribes the syntax of a crontab file

In few words you can schedule a job by populating your own crontab. Use the command crontab -e to edit it and add lines like this:

Code:

35 17 * * 3 $HOME/test.sh

in this example the script $HOME/test.sh is executed at 5:35 PM every Wednesday. Good luck!

I'll take a look at it, I'm sure I'll figure it out now!

Thanks for your help!
