recursive replace string in all files with specific name	Can't Post

i need a script that recursively searches a directory for files of a specific name like "*.props", and it replaces a string in each of the matching files that it finds.

That's even simpler, friend :)

$ find . -name *.props -exec perl -p -i -e 's/string_to_replace/new_string/' {} \;

Best regards:)

Did anyone write a script for you? If not I can write one.

$ find . -name *.props -exec perl -p -i -e 's/string_to_replace/new_string/' {} \;

So, let's say I want all *.php, *.htm*, *.xml, *.css, *.js files to be stripped of preceding spaces (indent code) and double newlines/linebreaks, for example,
this:

Code

<?php 
 
// --------------------------------------------------------------------------- 
// 
// LICENSE: 
// 
// This file is part of . and all its parts are licensed under 
// the GPL version 2. see: http://www..net/help/help_about_gpl.php 
// for more information. 
// 
// --------------------------------------------------------------------------- 
 
// First line defense. 
if (file_exists(dirname(__FILE__)."/first_defense.php")) { 
	include_once(dirname(__FILE__)."/first_defense.php"); 
	block_refererspam(); 
 
      } 
 
 
define('__SILENT__', TRUE); 
 
// apparently also defined in pv_core 
// $marco (who hates php notices) 
// define('IN', TRUE); 
 
define('LIVEPAGE', TRUE); 
 
include_once("v_core.php");

should become:

Code

<?php 
if (file_exists(dirname(__FILE__)."/first_defense.php")) { 
include_once(dirname(__FILE__)."/first_defense.php"); 
block_refererspam(); 
} 
define('__SILENT__', TRUE); 
define('LIVEPAGE', TRUE); 
include_once("v_core.php");

Does anyone have that laying around? ;-)

Stripping tabs, spaces, empty lines and comments from an entire webserver doc root (plus subdirs), without leaving a backup (assume a full backup exists).

Also, in HTML of course double spaces are only important if they are enclosed by <PRE> tags, right?
One can make a long line of javascript, css and html code (except the text echoes and such). I used to have a handy DOS tool for this, but it got lost over the years.

I can run this as root from a centos linux shell, so no crap with permissions. (And yes, I know, being root is bad. Not for this task though..)

The script can be run by me as somescript.sh, like

Code

#!/bin/sh 
$ perl -pi -e 's|[old_string]|[new_string]|g' [file]

Thanks in advance! I'll credit you on my website if you can make this for me. ;-) I love Perl and RegExp. They're my favorite tools!
