shell script

[Sanjiv Sharma_1]

Hi All,

I find that in one of my server /var/spool/cron/tmp is growing very fast and sometime new files are created and which grows too.

Pls. note sometime new files are generated in /var/spool/cron/tmp.

I am looking for a shell script which will read all the files under /var/spool/cron/tmp and trim them to 0KB.

I want to schedule this script to run once a day.

Thanks and pts in advance.

Hi,

That's easy:

for FILE in `ls /var/spool/cron/tmp`
do
cat /dev/null > $FILE
done

That's it!

Hi,make a script first (cutcron.sh):
#!/usr/bin/sh
for fn_name in /var/spool/cron/tmp
do
> /var/spool/cron/tmp/$fn_name
done

The make a cron to run this script:
#chmod 755 cutcron.sh
#crontab -e
0 0 * * 0-6 /cutcron.sh

Is this really you need?

What you need is a find command.

This is not exact because my HP box isn't built yet.

find /var/spool/cron/tmp +msize ### -exec rm {} \;

That is the basic structure. You may want to make a list for later removal instead of zapping the files straight away.

Also, I forget right now whether msize is in kilobytes or what, so play around a bit.

This is a good way to go though.

Have a look at this one:

for file in /var/spool/cron/tmp/*

Try this script from here:

You will need to make some modifications.

Hi,

you got a lot of replys how to trim your tempfiles. But i think it would be better to check why these files are created. It should be possible to find a configuration where these files are not created in the first place.

check your crontabs. I think the "problem" could be that you don't redirect your STDERR to a file or /dev/null.

Do something like this:

1 23 * * 1-5 yourscript 2> /dev/null

Hope this helps

Regards Stefan

Hello!

for file in /var/spool/cron/tmp/*
do
> /var/spool/cron/tmp/${file}
done

will truncate all files in /var/spool/cron/tmp
