running a Simple script from Webmin


I am setting up filesystem backup in webmin. I am saving the backups to a file /backup/backup.tar

Every backup overwrites the backup.tar file.

The webmin backup module has a option to run a command after the backup is run.

I want to run this script from webmin after the backup

(I found this on this forum)
# script=dname
#parameter $1 is the existing file name
dt=`date +%y%m%d`
mv $1 $1$dt

I can run it from root manualy and it works. but it doesn't work from webmin.

Can someone tell me how I get this to work.

Or is their another command I can use?

I want the backup.tar file name to be changed to backup.tar+ today's date

I'm very new to linux so please answer in simple english.

I suspect you want to replace $1 in your script example with /backup/backup.tar. So it would read:-
# script=dname
dt=$(date +%y%m%d)
mv /backup/backup.tar /backup/backup.tar.$dt
In scripts, $1 means the first parameter passed to the script. Also, I prefer the $() syntax rather than using the back quoted syntax. It makes it less confusing when reading the script with odd fonts. So, dt=$(date +%y%m%d) will still put the correct value into $dt.

Anyway, see how that goes.
