Re: Passing parameters to Perl Script

If you give your input to the script in a via pipe, it will be acessible on standard input, not in the argument list.

# your above script will work with this invocation:

perlscript one two

Alternatively Use the -n switch to perl itself, which causes your code to run in a loop with $_ set to a line of input every iteration (see perlrun for more details):

#!/usr/bin/perl -n

use strict;
use warnings;

my @words = split;   # "split /\s+/, $_", more or less
print "passed $_\n" for @words;

If that is to be run under Windows, you will need to - wrap your script into a batch-file using perl2bat `c:\> pl2bat scriptname c:\> echo 1 2 3\|scripname.bat` [download] - or pipe to perl.exe `echo 1 2 3\|perl.exe scriptname` [download] because of some limitations of the Windows-shell holli, /regexed monk/	[reply] [d/l] [select]

More specifically I've been using pl2bat and much to my surprise and disappointment I've noticed that I cannot use redirection of output (I had to add '-o' cmd line switches to "utilities" only moderately more complex than one-liners!). Don't know about input... I would check by myself but I'm under Linux now and I won't have access to a Windoze machine up until this evening...	[reply]
