Re^2: formatting STDOUT

Im running a binary which returns text - without me being able to do any handling e.g. concatenating strings. I want to change the default formatting to include a timestamp.

You can capture the output from an executable file by using backticks ``. Then, you can do whatever you want to the output: add a prefix, a suffix, or change it completely with regular expressions. In the following code, I'm capturing the output of `echo` and prefixing the date. Replace `echo` with the binary of your choice. use strict; my $system_call = `echo hello world`; my $output = scalar(localtime())." $system_call"; print STDOUT $output,"\n"; # output # Tue May 31 09:04:22 2005 hello world [download] If this isn't what you are looking for, please be more explicit in your posts. lupey	[reply] [d/l] [select]

echo

use strict;
my $system_call = `echo hello world`;
my $output = scalar(localtime())." $system_call";
print STDOUT $output,"\n";

# output
# Tue May 31 09:04:22 2005 hello world
