From my bashrc... # type cidrcon cidrcon is a function cidrcon () { for a in $*; do echo $a; done | perl -e "use Net::CIDR::Lite; \$cidr = Net::CIDR::Lite->new(<>) ; \$_ = join (\"\n\",\$cidr->list) ; print \"\$_\n\";" } Obviously requires Perl and the Net::CIDR::Lite module. I do not recall why the implementation is so weird, but I've been using it for decades(!?) > I didn't pay close attention to the list, but I did see that it was range > based and would need some conversion. -- I have added it to my pile of > things to look at more closely later. > > > > -- > Grant. . . . > unix || die -- Bill Cole b...@scconsult.com or billc...@apache.org (AKA @grumpybozo and many *@billmail.scconsult.com addresses) Not Currently Available For Hire
