tarball or gzip doing on unix

[weirdami]

How do I do one of those tar ball things or gzip dealies on a unix system? I have an email directory on Sparc something, and I want to squish up all the emails into one file.

Really, I suppose, I want to be able to type in a command that indicates which directory to archive, and have it archive all the files into one file, rather than into a bunch or individually archived files, which seems to be all I know how to do. :-(

man files are evil, which is why I'm asking you knowledgible folks. :-)

Thanks, guys, it worked first time. That -z thing wasn't in the -h, so I guess you were right about it not being on Solaris. Hadda gzip. Now my many emails take up tiny space. :-)
