Can't be done with a regular expression search & replace. BBEdit can help
though, with a custom filter. The specification is somewhat incomplete, but the
following python script should help (note that whitespace is significant in
Python). Save in the 'Text Filters' directory in the BBEdit directory in the
application support directory within your Library (hidden) folder.
#!/usr/bin/env python
import sys
import re
pat = re.compile('^(\d+),(\d+)(.*)$')
for line in sys.stdin:
line = line.rstrip() # remove trailing newline (and other whitespace)
m = pat.match(line)
if m:
for i in xrange(1,int(m.group(2))+1):
sys.stdout.write("{0}_{1}{2}\n".format(m.group(1), i, m.group(3)))
else:
sys.stdout.write("{0}\n".format(line))
