Re: keeping the two latest files on a folder
Hi Guys, that's me again.. I'm stuck again with sed to make a change
to a file.. sorry if it sounds off-topic.. but I need your help :-).
I've just want to change on a file this line:
vif = [ 'ip=167,112,134.223,mac=00:16:3E:FD:58:B8']
to:
vif = ['ip=167,112,134.223,mac=00:16:3E:FD:58:B8,vifname=veth216','ip=10.1.1.1,mac=00:16:3E:FD:58:BB,vifname=veth216a']
AND, if it's possible to change tha last two entries of mac address,
B8 to C8 for example..
thanks in advance
regards,
Israel.
