Bash BkUp script

drmjh · 10-18-2009, 04:07 PM

I am trying to write my first script. It's not much of an effort, but I would like to understand why it doesn't work and the principle behind the correction.

Code:

su

growisofs -Z /dev/dvd -dvd-compat -r -v /home

It executes the 'su' and accepts my PW and then stops.

su starts a new shell.

If you want to run the command as root, use sudo or try su -c "command"

Thanks everybody!
The fact that a new shell was opened I assumed but I also assumed that the same thing would happen if I used "sudo" or "su -c" and that's why I didn't try them.
