I want to extract the usb lable attached to my linux system. I have written some code in python, it works fine, but I want it to be less complicated. Any ideas ... Thanks.
Here is the code:
#!/usr/bin/env python
import commands
import os
str1=commands.getoutput('sudo blkid')
name=str1.splitlines()
for x in range(len(name)):
if '/dev/sd' in name[x]:
print name[x]
str2=name[x].split(" ")
print str2
for y in range(len(str2)):
if 'LABEL' in str2[y]:
print str2[y]
str3=str2[y].split('=')
print str3
for z in range(len(str3)):
if 'LABEL' in str3[z]:
print str3[z+1]
You can use the options on
blkid
to simplify your task. In this case the-s
to specify that you are only interested in theLABEL
.Then you can find the value of that by reverse searching for the
=
character, like so:
