Could be done using regular expressions. Ususally for such tasks one
would prefer pythons string manipulation functions, but if you want to
preserve whitespace, I think a rex is in order here:
import re, sys
new_name = "foobar"
rex = re.compile(r'(^.*username *=[^"]*")([^"]*)(".*$)')
for line in sys.stdin:
m = rex.match(line)
if m is not None:
line = "%s%s%s\n" % (m.group(1), new_name, m.group(3))
sys.stdout.write(line)
use with
python script.py < config_in > config_out
