Above script requires sudo!

Another example!
Say a site closes down and your site used to rely on this site! and you have thousands of pages to edit and comment out lines refereing to a dead site this is easy with following example!

Code:

./web_file_replace.sh "require_once('tracker.php');" "\/\/include(\"tracker.php\");"

Code:

Basically chars like " $ and / need escaping!!!

 (maybe more)

Even More Examples

Code:

./web_file_replace.sh "require_once('tracker.php');" "\/\/include(\"tracker.php\");"
./web_file_replace.sh "include (\"tracker.php\");" "\/\/include(\"tracker.php\");"
./web_file_replace.sh "require('tracker.php');" "\/\/include(\"tracker.php\");"

./web_file_replace.sh "<? " "<?php "

./web_file_replace.sh "\/\/\/\/" "\/\/"

 ./web_file_replace.sh "\/\/ \/\/" "\/\/"
