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..

sed -i
'/^vif/s/B8.*$/C8,vifname=veth216'"'"','"'"'ip=10.1.1.1,mac=00:16:3E:FD:58:BB,vifname=veth216a'"'"']'
file.cfg
Hi Javier,

It doesn't work for me:

server:/tmp# cat a
vif = [ 'ip=167,112,134.223,mac=00:16:3E:FD:58:B8']

server:/tmp# sed -i
'/^vif/s/B8.*$/C8,vifname=veth216'"'"','"'"'ip=10.1.1.1,mac=00:16:3E:FD:58:BB,vifname=veth216a'"'"']'
a
sed: -e expression #1, char 87: unterminated `s' command


regards,
Israel.

As it is dificult to read see this explication:
If you want to use a ' inside replace string such is the case you must:
type ' to close string
Then type " to open a new concatenated string
type ' to write '
type " to close the concatenated string
type ' to concatenate the next string (following with the replace string)
