RE: help with expect script

You can use "lsb_release -a" to determine what linux distro you have, but it is a bit verbose.
lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 6.0.6 (squeeze)
Release: 6.0.6
Codename: squeeze

Use "lsb_release -s -c" to get just the codename.

You can use "$(lsb_release -s -c)" to get just the codename as a variable in your if statement.

You could also use "$(uname -n)" as a variable in your if statement as well.
