=>Thanks, Andy. Is not there a native Linux command to compare strings?
Hmm. The natives are restless tonight...
Ok. Let's see if we have something betterer...
function streq ()
{
if (( $# != 2 ))
then
echo 'Wrong nr of args' 1>&1
return 2
fi
[[ "$1" = "$2" ]]
}
Put this if your .bashrc to define the streq function. Then to invoke just
say
streq horsepoopies liberals
The result will be in $?. O means equal, 1 means not equal, 2 means wrong
nr of args.
