Command output string manipulation possible in one line?

This has been bothering me for 3 days.

$> hostname
cepsun64amd

And I just want "cepsun",

I would normally do h=`hostname`; ${h%%64*}

But I am looking for a one-liner just for my own knowledge, because if there is a way to do this, I should know it by now.

Anyway, so is this possible?

P.S. I realize there are other ways to do this without using ${%%}, but I have ran into this problem like 4 times within the past few days where it would be really convenient and clean to just use ${VAR%%PATTERN}.

Thanks

SEND-UUCP(8)						      System Manager's Manual						      SEND-UUCP(8)

NAME
send-nntp, send-ihave - send Usenet articles to remote site SYNOPSIS
send-nntp [ -d ] sitename:hostname | sitename [ sitename:hostname | sitename .. ] send-ihave [ -d ] sitename:hostname | sitename [ sitename:hostname | sitename .. ] DESCRIPTION
The send-* utilities are scripts that process the batch files written by innd(8) to send Usenet articles to a remote NNTP site. The sites to be fed may be specified by giving sitename hostname pairs on the command line. The sitename is the label the site has in the newsfeeds file, the hostname is the real hostname of the remote site, a FQDN (Fully Qualified Domain Name). Normally, the sitename and the hostname are the same, and as such don't have to be specified as sitename:hostname pairs but just as a sitename. send-nntp starts an innxmit to send the articles to the remote site. send-ihave encapsulates the articles in an ihave control message and uses inews to send the articles to a to.sitename pseudo-group. Using send-ihave is discouraged, nobody uses it anymore and even the author of this manpage is unsure as to how it actually works or used to work. send-* expect that the batchfile for a site is named <pathoutgoing in inn.conf>/sitename. To prevent batchfile corruption, shlock(1) is used to ``lock'' these files. OPTIONS
-d The ``-d'' flag causes nntpsend to send output to stdout rather than the log file <pathlog in inn.conf>/<program-name>.log. NOTES
You should probably not use send-nntp, but innfeed, or if that is not possible, nntpsend. The usual flags for a batch file for send-nntp are ``Tf,Wfm''. SEE ALSO
