Top Forums Shell Programming and Scripting Prepend TimeStamp to STDERR & STDOUT to a file Post 302675767 by Corona688 on Monday 23rd of July 2012 01:54:41 PM

About the only thing that's going to work the same way in all three is perl.

Code:
#!/usr/bin/perl

use POSIX qw(strftime);


while(!eof(STDIN))
{
        $line=<STDIN>;
        print strftime("%F %T ", localtime), $line;
}

Redirect a stream through this script and it will add timestamps to it.

This module provides routines to format dates. They correspond to the libc routines. &strftime() supports a pretty good set of coversions -- more than most C libraries. strftime supports a pretty good set of conversions. The POSIX module has very similar functionality. You should consider using it instead if you do not have allergic reactions to system libraries. GENESIS
