stdout/err redirection

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi monks, i use a logging package which i inherited from a previous programmer. it redirects STDOUT to both the log file and the console, and STDERR to only the log file.

open LOG, ">> $logfile";
open STDERR, ">&LOG";
select LOG; $| = 1;
select STDERR; $| = 1;
select STDOUT;

i'd like to redirect both STDOUT and STDERR to the log file and console, but i'm having trouble doing so. can someone help?

There may well be a more elegant way to do this than mine, but if your using Unix/Linux, you may have some success with the `tee` command. Something along these lines: `#! /usr/bin/perl use strict ; use warnings ; $\|++ ; my $logfile = 'my_log.txt' ; open STDOUT, "\| tee $logfile" ; open STDERR, ">&STDOUT" ; print STDOUT "I'm going to standard output.\n" ; print STDERR "I'm going to standard error.\n" ;` [download] Both messages go to the console, and to the log file. _______________ D a m n D i r t y A p e Home Node \| Email	[reply] [d/l] [select]

This is not a perl solution, but if you need redirection for the lifetime of a process. socat is a sure bet. NTK said: : . If Perl is the Swiss Army chainsaw of programming languages, then SOCAT is the Swiss Army chainsaw of, uh, shell/networking tools. BTW, NTK tracking section is a must read every friday evening. socat is way better than netcat. -- stefp -- check out TeXmacs wiki	[reply]
