A bit of (Linux) scripting help needed

jibbajabba

I install you all sorts of Linux cluster and configure the world, but what I never really learned (about time I know) is shell / bash scripting

Once a month I go through my Linux server and zip up the weblogs with an awefully simply poor writen DIY script.

custnum=1
for customer in `ls /home | grep -v mysql | grep -v titan`
do
echo $custnum
cd /home/$customer/logs
tar cvfz jun2008.tar.gz log.200806*
for logfile in log.200806*
do
rm $logfile
echo $logfile
done
custnum=`expr $custnum + 1`
done

What I am looking for is finding a way to use a cronjob instead without manually changing these lines

tar cvfz jun2008.tar.gz log.200806*
for logfile in log.200806*

I need a way for the script to query the previous month (script should run 1st of the month) and "zips" up the logfiles accordingly. So if i.e. the script runs February 1st, is should automaticlly go through every folder and tar up all log.201001*

Makes sense ?

Any help is highly appreciated ..

For the date you could use the date command, clean it up with regular expressions or sed... and then pass it as a variable in the name of the file...

hehehe simple...

Hehe, yea "that" simple

Well I came so far to show the last month as number

date +"%m" --date='1 month ago'

and written word

date  --date='1 month ago' +%B

Now I have to somehow throw everything in one pot and make a script out of it

Think it through and it looks like you'll have it sorted out.
