which is best searching option
Hi,
I need one help for choosing best option among sed, perl and awk.
I need to search and replace thousand files for a text and need to replace it. I am in confusion for choosing the option for best results.
Because by using sed option its taking too much time for searching and replacing text in all thousand files. And redirecting the modified files to the same directory.
At present i am using sed for the above.But its taking 2 hrs to replace and redirect the modified files .
Can anyone suggest for choosing best among sed ,perl and awk?

tk::fbox
FBox(3pm) User Contributed Perl Documentation FBox(3pm)
NAME
Tk::FBox - a file dialog
SYNOPSIS
use Tk::FBox;
$file = $mw->FBox(...)->Show;
DESCRIPTION
"Tk::FBox" is the dialog implementation behind the "getOpenFile", "getSaveFile", and "chooseDirectory" method calls in the Unix/X11 world.
As such, it supports all options for these methods and additionally:
-sortcmd => sub { $_[0] cmp $_[1] }
Specified a callback for changing the sorting of the icons in the "IconList" widget. By default, perl's "cmp" operator will be used.
From the source code:
# Using -sortcmd is really strange :-(
# $top->getOpenFile(-sortcmd => sub { package Tk::FBox; uc $b cmp uc $a});
# or, un-perlish, but useable (now activated in code):
# $top->getOpenFile(-sortcmd => sub { uc $_[1] cmp uc $_[0]});
This is an experimental option!
-type => $type
Type should be "open" for choosing existing files to open (default), "save" for choosing existing or non-existing files to save, or
"dir" for choosing directories.
-filter => $glob
A file glob to restrict displayed files. This is only active if no -filetypes are defined.
-force => $bool
If true, then there will be no dialog if a file already exists.
