-x will tell you whether you have execute permissions for the file (or
directory), if that's what you're looking for. If you mean that you
want to check CPU architecture, binary compatibility, etc., your best
bet would probably be to somehow parse the output of the 'file' command.
$ if [ -x /etc/inetd.conf ] ; then echo "executable" ; else echo "not executable" ; fi ;
not executable
$ if [ -x /bin/bash ] ; then echo "executable" ; else echo "not executable" ; fi ;
executable
