directing output of system()

[Murugesh]

Hi all,
when system() is invoked, is there any way to direct the output into
a file.
Thanks

May I suggest that you read the documentation for system() instead of
asking hundreds of programmers to read it for you.

perldoc -f system

perldoc -f system

In doc, it is said that we can get the exit status of the command.My
question is different.

In doc, it is said that we can get the exit status of the command.

It also suggests (a couple of sentences later) another method for
running system commands if you are interested in capturing the command's
output.

My question is different.

Different compared to what?

Yes, just you would in the shell.


system "ls -l >redirected.file";


Haven't you already tried that?

Seems quite simple to me (I hope I got you right):

system('command 2>> /path/errors >> /path/results');

Best regards

Yes - don't use system(). ;-)

Use backticks, qx(), or open() a pipe to receive the output.

That's if you want to capture the output of the command for use in your Perl
code - if *all* you need to do is direct it to a file, nothing else, then
Tad's suggestion of a simple shell redirect is perfect.

Yes!! I never thought that way! Thanks.

There are several ways I can think of to do this. One is implied within
the documentation for system() itself.

perldoc -f system
perldoc -f open

In which way does the third sentence in the third paragraph of said
documentation _not_ answer your question?
