[英]Getting MAC address only from ifconfig
I'm trying to use grep to get me en0's mac address. 我正在尝试使用grep获取我en0的mac地址。 What I'm trying to do is store that in a variable called original_mac.
我想做的是将其存储在一个名为original_mac的变量中。
This does not seem to be working though. 不过,这似乎不起作用。 When I type
ifconfig en0 | grep ether
当我键入
ifconfig en0 | grep ether
ifconfig en0 | grep ether
i get ether: <mac_address>
. ifconfig en0 | grep ether
我得到ether: <mac_address>
。 I just want to get the mac address part of it. 我只想获取其中的mac地址部分。
#get original mac address
global original_mac
original_mac = subprocess.check_output("ifconfig en0 | grep ether | awk {print $2}")
print "mac: "+original_mac
You have to either pass a list to check_output or use 'shell=True'. 您必须将列表传递给check_output或使用'shell = True'。 So this should work:
所以这应该工作:
original_mac = subprocess.check_output("ifconfig en0 | grep ether | awk {print $2}", shell=True)
