Re: string match simplification?

    This seems ok:  (and never mind deciding on how long the extension
    can be):
    
    #!/usr/bin/zsh
    
    filename=$1
    extension=${filename:e}
    # just in case there's a trailing dot: don't remove in unless there
    is an extension.
    [ "$extension" ] && filename="${filename%.*}"
    echo filename is: $filename
    echo extension is: .$extension # I'll keep the dot on the extension.

That's :r.  (It stands for "root".)

There's also :h and :t (head and tail) for pathnames: :h is the directory component, and :t the bare filename.  So if filename=/foo/bar/baz.txt you have:

Such resources!  Gotta lock myself in a punishment cell and read the manual just to know what's available.

Thanks guys.  There's no better help anywhere.
