But the behaviour is different the next time, as chad originally reported. $ cat globtest #!/bin/perl -l mkdir "tst"; chdir "tst"; open F, ">tst1"; close F; print scalar glob "*" for 1..4; print glob "*" for 1..4; $ perl globtest tst1 tst1 tst1 tst1 tst1 tst1 $ -- Paul Johnson - [EMAIL PROTECTED] http://www.pjcj.net -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
