So now that that makes sense to you, let me say that you should use both solutions :) Quoting $line ensures that special meta-characters aren't expanded. For example, if $line contained a *, then the shell could expand it with files in the current directory. And using $@ instead of $1 in LogIt is just more flexible and is closer to your actual intention of "log everything I pass on this line." -- Garrick Staples, GNU/Linux HPCC SysAdmin University of Southern California 09 F9 11 02 9D 74 E3 5B D8 41 56 C5 63 56 88 C0 --- Thanks, that helps explain it...and I did incorporate both!
