Re: test for existance of external program

2005-04-12 19:28:43
What's the recommended way for testing whether some external program
$PROG exists?

      :0
      * ? [ -f $PROG ]

Ok ok ok. But it fails with PROG=awk, the other tests in [ are the same
with that. That might leave * $? sh -c "type '$PROG'", is that really
less efficient? (Not that a few microseconds of CPU are worth more than
my time.)

Thanks,

Volker
