Hi,
Hello,
I'm currently writing a script which contains a subroutine to write
data to files.
Currently I use
open $fh, '>', "$basedir/$userdir/$outfile" or die "Can't write: $!\n";
which has the disadvantage, that the whole script dies if e.g. the
userdir is not available.
Could you give me an advise how to just exit the subroutine if opening
the filehandle fails, without exiting the whole script?
Yes, just exit (return) from the subroutine:
open my $fh, '>', "$basedir/$userdir/$outfile" or do {
warn "Can't write: $!\n";
return;
};
