I think
perl -e 'print grep m[/horseradish],`mount`'
is hard to beat for its simplicity. Note I'm using Perl's
built-in grep; there's no need to run the system's grep.
You can code something like
--------------------------------
if( grep m[/horseradish],`mount` ){
useMountedHorseradish();
}else{
dealWithUnmountedHorseradish();
}
--------------------------------
because Perl's grep will return an empty string if 'horseradish'
isn't found in `mount`, and an empty string is logically false,
whereas any nonempty string is logically true.
