Quote - Yep - gzip and gunzip are nestled in OSX. You can do it yourself, or be lazy and use this (name it "pack", or whatever you like):

---

#!/bin/sh<br></br><br></br>
# cheesy little script. do whatever you like with it.<br></br><br></br>
# usage:  pack <file> [newname]<br></br><br></br>
if [ "$2" != "" ];<br></br>
then<br></br>
     gzip -c $1 > $2.gz<br></br>
else<br></br>
     gzip $1<br></br>
fi<br></br><br></br>
exit
