Stopping functions breaking

Stopping functions breaking

[zzapper]

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.
