Re: Calling a Perl filter script from command line

Pipes don't pass stuff via ARGV, you need to read from STDIN in order to get information from them. For example,

if you were to make a test file called test.pl with the lines
#!/usr/bin/perl -w
print <STDIN>;

in it, then do a "cat test.pl |./test.pl"
it would print:
#!/usr/bin/perl -w
print <STDIN>;

Yes, pipes don't pass stuff via @ARGV, but `<>` does read from STDIN if @ARGV is empty. So `<>` is appropriate and that is not the problem. - tye (but my friends call me "Tye")	[reply] [d/l] [select]
