How to find MAC address and uids?

[Daniel T.]

I'm writing a script for work and to finnish it, I need two bits of
information which I'm having trouble finding.

1) How can I programatically find the MAC address of the machine? Is it
stored in a file I can look into? (MacOS X)

2) If I have a user name in a string how do I get his UID?

Thanks to anyone that can help.

What is syntax of this file ??

2) If I have a user name in a string how do I get his UID?

import pwd
pwd.getpwnam('spock') ('spock', 'x', 100, 101, '', '/export/home/spock', '/bin/bash')
pwd.getpwnam('spock')[2] 100

My Mistake
If you have access to /sbin/ifconfig (if MacOS X is FreeBSD based it should
be in /sbin) you can use something like this:

import os
a=os.popen('/sbin/ifconfig bge0|grep ether').read().replace('\n','').split()[1]
print a 00:30:84:b3:b3:3a

Important - replace bge0 your card name ...

2) If I have a user name in a string how do I get his UID?

import pwd
pwd.getpwnam('spock') ('spock', 'x', 100, 101, '', '/export/home/spock', '/bin/bash')
pwd.getpwnam('spock')[2] 100

$ ifconfig | grep ether | awk {'print $2'}
Note that there may be 0, 1 or many MAC addresses.

2) If I have a user name in a string how do I get his UID?

This gets the uid for 'james':
$ nireport . /users name uid | grep james | awk '{print $2}'

"man getpwnam" might help you find an answer.
