Subject: Re: How to gunzip a binary on the fly

If you mean the gzipped file is a shell script then it's pretty easy:
exec_gz () {
eval "$(gunzip -c $1)"
}
so you can do
exec_gz myscript.gz
In case the gzipped file is a binary (read: the file _before_ gzipping is a
binary) I think there is no way to do this. The OS (at least a few unices,
e.g. linux) needs the executable to be present as a file on a filesystem.
Pista
ps: Maybe the shell creates a temp file or pipe for the output of gunzip, I
can't check it right now.
