search and store a value from linux command output in to variable python - prazy29 - Apr-06-2018
Hi I am a python bigginer, I have a scenario where I need to search and select a particular value from linux command "df -h".
dumpe2fs 1.42.13.x5 (23-Mar-2017)
Inode count: 786432000
In this above output I need to store the inode count number in to a variable to use it for further calculation.
Can anyone explain how to use python regular expressions to do the above task?

Get the output using subprocess.
import subprocess
output = subprocess.run(['df', '-h'], stdout=subprocess.PIPE).stdout
output = output.decode('utf-8')
for line in output.split('\n'):
if line.startswith('Inode count:'):
inode_cnt = int(line.split()[1])Something like that.Btw, I don't get the number of inodes with
df -h.
