Question

Is there a way to do a JavaScript code find and replace using a batch file. Here is an Example:

Find: <script type="text/javascript" src="http://www.mega.edu/Course/WebCTfooter/footer.js">Footer</script>

Replace: <script type="text/javascript" src="http://www.mega.edu/Course/WebCTfooter/footer_ungrad.js">Footer</script>

Any help would be greatly appreciated.

Since you can use python, I recommend using a python program instead of a batch file, perhaps something like this:

#!/usr/bin/python

import shutil
import sys
import re

for path in sys.argv[1:]:
    print "processing " + path
    infile = open(path,'r')
    tmpfile = open(path+'.tmp','w')

    # make the replacements
    for line in infile:
        line = re.sub("/footer.js","/footer_ungrad.js",line)
        line = re.sub("/header.js","/header_ungrad.js",line)
        line = re.sub("/sample.js","/sample_ungrad.js",line)
        tmpfile.write(line)

    infile.close()
    tmpfile.close()

    # now move it back to the original file
    shutil.move(path+'.tmp',path)

Tested with python 2.4.
