in reply to perl glob

Normally this globbing would be handled by the shell, so your two commands would be

perl wrapper.pl *.ws
and
perl wrapper.pl test_*.ws
Leaving your script to work its way through @ARGV and process files.

To make it even simpler, you could just replace wrapper.pl with converter.pl, unless the wrapper script is doing something that you haven't shown here.

    Sorry for my poor english...

    The converter.pl is an other long programm which I have wrote for converting scripts in one programming language to the scripts in an other. But with converter.pl I can only convert one file in one go. E.g.:

    perl converter.pl abc.ws

    It will create a new script names abc.is. So I wrote this simple wrapper, to allow me converting several ws files in one go. E.g.:

    perl wrapper.pl .ws

    For instance, it converts abc.ws, efg.ws and hij.ws in one go, which I can't achieve with:

    perl converter.pl .ws.

    P.S.

    perl converter.pl *.ws

    also didn't work, probably because I also allowed users to define the output filename by themselves, e.g.:

    perl converter.pl abc.ws efg.is

    And here is the relevant codes in converter.pl:

    my $file_name = ""; if (scalar(@ARGV) == 2){ $file_name .= $ARGV[1]; } else { $ARGV[0] =~ s/(.+)\.\S+/$1/; $file_name .= $ARGV[0]; $file_name .= ".is"; }

    I checked here whether the user defined a name for the "is" file, if not the "is" file will take the same name with the "ws" file.

    Many thanks!
