> Nemmer er måske bash "parameter expansion":

Findes sikkert i man bash... :-) Ellers her:
http://www.gnu.org/manual/bash-2.05a/html_node/bashref_29.html

"${parameter%word}
${parameter%%word}
    The word is expanded to produce a pattern just as in filename expansion.
If the pattern matches a trailing portion of the expanded value of
parameter, then the result of the expansion is the value of parameter with
the shortest matching pattern (the `%' case) or the longest matching
pattern (the `%%' case) deleted. If parameter is `@' or `*', the pattern
removal operation is applied to each positional parameter in turn, and the
expansion is the resultant list. If parameter is an array variable
subscripted with `@' or `*', the pattern removal operation is applied to
each member of the array in turn, and the expansion is the resultant
list."

Meget smart... :-)

Med venlig hilsen Preben
