[SOLVED] scripting sudo

I want to run the following script called "backup":

#!/bin/bash

sudo -u postgres "pg_dump -Fc davical >davical.pgdump"

But when I run it, the error appears:

sudo: pg_dump -Fc davical >davical.pgdump: command not found

Anyone know what I am doing wrong?

Thanks!

Re: [SOLVED] scripting sudo

I'm not sure you can have redirection inside a command string like that.

I suspect you could put the command string in it's own script, or perhaps in a function within the same script, then use sudo to call the other script or function.

Thanks for the tip! Now it works:

sudo -u postgres bash -c "pg_dump -Fc davical >davical.pgdump"

Re: [SOLVED] scripting sudo

# Check for admin rights. If user is not an admin user, exit the script
if [ $UID != 0 ]
then
   echo "You need to be root to run this script! Exiting..."
   exit
fi

This snippet checks if you've sudo-ed it (or ran as root). All subsequent commands can be coded without sudo.
