Re: How to replace spaces with different chars?

In my initial response I answered your question about using system; however, it occurs to me that you probably want to capture that output and do something with it. So, if you replace

system("ls -1 $datum");
[download]

with

my @matches = `ls -1 $datum`;
[download]

you'll now have an array of matches that you can process further. If that processing was

print for @matches;
[download]

you'll get identical output to what I originally posted.

why not use `my @matches = glob($datum)` or `my @matches = <$datum>` directly? Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery}	[reply] [d/l] [select]

This was a follow-up to my previous post about system, which has: "This is not what you want to use to capture the output from a command; for that you should use merely backticks or qx//, ..." Of course, TMTOWTDI. :-) — Ken	[reply]

Hi Ken Sorry, I have to disagree. For numerous reasons it's best practice not to shell out for something which can be done inside Perl. (portability, performance, maintenance, security, ...) It's even a bit worse, because `ls` is useless, if you just need the shell's globbing. TMTOWTDI only covers this, if there is a good reason. Anyway, let me point you to older discussions instead of reiterating the reasons ° Re: perl one liner for csv file one field (useless use of cat and other awards References) Useless Use of Cat Award The wise coder Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery} °) thanks to eyepops++ for keeping this listed in his homenode! :)	[reply] [d/l]
