Top Forums Shell Programming and Scripting How To Run A For Loop In A Remsh? Post 302506227 by Perderabo on Saturday 19th of March 2011 10:09:11 AM

Although I answered the question that was asked, I always do as methyl suggests for any remote commands beyond a simple "uptime" or "date".

I do sometimes type in loops or quick function definitions at the command line locally as I showed in my example. So I stay up to speed on ksh syntax as well. Real example: I was on a broken system and cat and ls didn't work, nor did most commands. So I do a quick:
Code:
function mycat { while read l ; do echo "$l" ; done < $1 ; }
function myls { while [ $# -ne 0 ] ; do echo "$1" ; shift; done ;}

and I can look around with commands like "myls /etc/*" and "mycat somefile". It's very handy being able to pull stuff like that out of my hat when I need to.

NAME
POE::Loop::Tk - a bridge that allows POE to be driven by Tk SYNOPSIS
See POE::Loop. DESCRIPTION
POE::Loop::Tk implements the interface documented in POE::Loop. Therefore it has no documentation of its own. Please see POE::Loop for more details. POE::Loop::Tk is one of two versions of the Tk event loop bridge. The other, POE::Loop::TkActiveState accommodates behavior differences in ActiveState's build of Tk. Both versions share common code in POE::Loop::TkCommon. POE::Loop::Tk dynamically selects the appropriate bridge code based on the runtime environment. SEE ALSO
POE, POE::Loop, Tk, POE::Loop::TkCommon, POE::Loop::PerlSignals. AUTHORS &; LICENSING Please see POE for more information about authors, contributors, and POE's licensing. perl v5.10.1 2010-04-11 POE::Loop::Tk(3pm)
