GREP Regex Patterns

[TamedTech]

Hello Guys,

I'm terrible with regex patterns, but i'm looking to grep out a MAC address, which foolows the following pattern.

XX:XX:XX:XX:XX:XX

And the X's can be iether Numbers or Letters.

How could i build this into a GREP statement with the regex pattern.

Thanks,

Rob

How about:
[tt]
grep -i '[0-9a-f]\{2\}:[0-9a-f]\{2\}:[0-9a-f]\{2\}:[0-9a-f]\{2\}:[0-9a-f]\{2\}:[0-9a-f]\{2\}'
[/tt]
This seems to work with GNU grep.

And let's repeat a good idea (grouping):

grep -i '\([0-9a-f]\{2\}:\)\{5\}[0-9a-f]\{2\}'

Hey Chapps,

Thanks for those suggestions, i'll give them a run through in the morning and let you know how I get on, this should make life much more efficient than my current process's.

Many Thanks,
