save output to array

[a]

Hi,
For example,
If I want to save the output of system("ls") to an array, what should I do?
Thanks a lot

If I want to save the output of system("ls") to an array, what should
I do?

I would follow the advise that is given in the man page and the FAQ about of
system().
Like e.g. the fourth sentence in the third paragraph of "perldoc -f system".
Or the answer to "perldoc -q system": "Why can't I get the output of a
command with system()?"
Or any of the gazillion previous threads about this topic.

Having said that, why do you want to capture the output of 'ls' in the first
place?
There are several Perl builtin functions that provide the same
functionality, no need to shell out an external process.

Thanks for you reply.
Actually, I need to look for the file path of the given file name.
Do perl have support for this?
Thanks a lot.

One can download the core module File::Find from the CPAN

Why do you write that? Who are you talking to? What problem does your
solution solve?

Please quote when replying.

Well, yes, one *could* download a core module from CPAN, I suppose, but
why would one *want* to? Core modules.... are core modules. They are
already included in your distribution of Perl.

Can you explain what problem you are attempting to solve?

Apologies if my pointer was dangling.

Just wanted to help "a" with the requirement of file path lookup given
a file name & file::find does help him towards achieving what he wants
with out the need for him to execute the system utilities.

Please correct me if I am wrong.

You are not wrong that File::Find could help the stated problem.

You are wrong in that you are not quoting any context when you are
posting your replies (see how I've quoted what you wrote above? You're
not doing that) so that no one who A) is not reading this newsgroup in
a threaded manner, or B) is using a newserver which has not yet
received the original message, has any idea what you're talking about.

You are also wrong in that File::Find would need to be downloaded via
CPAN. It is already included in the standard Perl distribution. If
you have Perl, you have File::Find. Just use it.

See perldoc File::Basename

Sometimes an external process is easier, so don't be afraid of it.
