You'll then hit another problem because you want to have nested backticks (one pair for basename and another for hostname). Bash supports '$()' as an alternative to backticks that does allow nesting - writing $(hostname) is equivalent to `hostname` and allows you to write $(basename $(hostname)). I'm not sure basename is going to do what you want here though - are you looking for the short host name or the domain name? The basename command separates components of a path based on the '/' (or whatever the system defined path separator is). E.g.: $ DNS=$(basename $(hostname)) $ echo $DNS breeves.fab.redhat.com If you just want the short hostname you can pass -s to hostname: $ ssh pe1950-1.gsslab hostname -s pe1950-1 Or the domain with -d: $ ssh pe1950-1.gsslab hostname -d gsslab.fab.redhat.com Have a look at the man page for hostname for more options.
