Here it is:

Code:

#!/usr/bin/env ksh

cd /home/username/public_html/tests/
find . -name "*.php" | while read file
do
    echo "munging: $file"             # nice to see progress as it works
    mv "$file" "$file-"      # back it up
    awk '     # read the file and delete the block of php code
    /<?php/ { drop = idx = 0; snarf = 1; }  # start of a block; start buffering

    /?>/ {                  # end of a block
        if( ! drop )        # magic string not found -- show this block
        {
            for( i = 0; i < idx; i++ )
                printf( "%s\n", buffer[i] );
            printf( "%s\n", $0 );
        }

        snarf = 0;          # turn off buffering
        next;
    }

    ### change the string between the slants to be something unique to the block you wish to delete. 
    /PHP_STRING/ { drop = 1; }    # magic string found, drop if we're in a php block

    snarf {                 # if buffering, hold the record until end of block reached.
        buffer[idx++] = $0;
        next;
    }

    { print; }              # not buffering, just print the record.
    '  "$file-" >"$file"
    if (( $? > 0 ))            # handle failure by putting the file back in place
    then
        echo "edit of $file failed" >&2
        mv "$file-" "$file"             # restore original
    else
        rm "$file-"               # worked, delete backup 
    fi
done

Shouldnt the first line be:

#!/bin/ksh

snarf

snarf(1)						      General Commands Manual							  snarf(1)

NAME

       snarf - Simple Non-interactive All-purpose Resource Fetcher

SYNOPSIS

       snarf [-avqprzm] URL [outfile] ...

DESCRIPTION

       Retrieves data from a variety of protocols, namely http, ftp, and gopher.

USAGE

       snarf is invoked with any number of URLs and outfiles. If an outfile is not specified, snarf preserves the remote file name when saving.

       For  example, snarf http://foo.bar.com/images/face.gif will retrieve the file ``face.gif'' to the local system.	In the event that there is
       no filename (the url ends in a slash), the data is retrieved and stored in the file index.html for http URLs, ftpindex.txt for ftp URLs, or
       gopherindex.txt for gopher URLs.

       Using a dash, "-", as the outfile causes snarf to send its output to stdout rather than a file.

       To log in to an ftp server or website that requires a username and password, use the syntax http://username:password@site.com/. If you omit
       the password, you will be prompted for it.

       Snarf has a built-in option to download the latest version of itself; simply run snarf LATEST.

   OPTIONS
       -a     Causes snarf to use "active" ftp. By default, snarf uses passive ftp, and, if the server does not support it, falls back	to  active
	      ftp. Using the -a option will avoid the initial passive attempt.

       -r     Resumes an interrupted ftp or http transfer by checking if there is a local file with the same name as the remote file, and starting
	      the transfer at the end of the local file and continuing until finished. This option only works with HTTP  servers  that	understand
	      HTTP/1.1 and ftp servers that support the REST command. snarf uses this option automatically if the outfile already exists.

       -n     Don't resume; ignore the outfile if it exists and re-transfer it in its entirety.

       -q     Don't print progress bars.

       -p     Forces  printing	of progress bars. Snarf has a compile-time option for whether progress bars print by default or not. The -p option
	      overrides the -q option. In addition, if progress bars are enabled by default, snarf suppresses them when standard output is  not  a
	      terminal. Using -p will override this behavior.

       -v     Prints all messages that come from the server to stderr.

       -z     Send a user-agent string similar to what Netscape Navigator 4.0 uses.

       -m     Send a user-agent string similar to what Microsoft Internet Explorer uses.

       Each option only affects the URL that immediately follows it. To have an option affect all URLs that follow it, use an uppercase letter for
       the option, e.g. -Q instead of -q.

ENVIRONMENT

       Snarf checks several environment variables when deciding what to use for a  proxy.  It  checks  a  service-specific  variable  first,  then
       SNARF_PROXY, then PROXY.

       The service-specific variables are HTTP_PROXY, FTP_PROXY, and GOPHER_PROXY.

       Snarf also checks the SNARF_HTTP_USER_AGENT environment variable and will use it when reporting its user-agent string to an HTTP server. In
       the same spirit, it also uses the SNARF_HTTP_REFERER environment variable to spoof a Referer to the web server.
