I use Python instead of shell scripts for anything that is not
completely trivial. Here is a small program for finding all the links in
a page of html:
#! /usr/bin/end python
if len(sys.argv) != 2:
raise Exception, 'program must have exactly one argument.'
infile = sys.argv
page = open(infile, 'r').read()
lowerpage = page.lower()
start = 0
start = lowerpage.find('href="', start)
if start == -1:
start = start + len('href="')
end = lowerpage.index('"', start)
print page[start : end]
