Since the only alternative to a regexp presented so far was using python
(which has been considered a bit heavy-weight), I'll suggest some hacky
shell code instead (here as a one-liner, would probably be nicer to do this
as a function):
---
[me@you ~]# ip=01.02.00.0004; for d in $(echo "${ip}"|tr '.' '\n');
do myip="${myip}"$(printf "%i" "${d}")"." ; done; echo ${myip%.}
1.2.0.4
