Hi
I'm writing a function (see below) which I call such
> pub fred
I want it to cd to any directory beginning fred, if there 0 or more
than 1 matches I wish to carry on in the script.
However whatever I try 0 or no matches breaks the script.
HELP PLEASE
function pub
{
if [ $# -gt 0 ];
then
echo $?
builtin chdir $1* &> /dev/null
echo $?

Set the no_nomatch option, then the failed glob won't cause a fatal error.
The cd will fail, but won't stop later things working.
The best way to do this is probably to add
setopt localoptions nonomatch
at the top of the function. This will ensure the options are restored
when the function exits.
