I am trying to get the bash output to a variable and then hide the output afterwards in the command itself.

I could find a way to hide the output using /dev/null 2>&1 at the end of the command like below:

kubectl get deployments -n kube-system | grep minions /dev/null 2>&1

It hides the output, but I need to get its output to a variable and then hide it (so I will still have the output but command wouldn't show the output in terminal)

How can I do this?

Like this :

import subprocess

cmd = "kubectl get deployments -n kube-system | grep minions"
ps = subprocess.Popen(cmd,shell=True,stdout=subprocess.PIPE,stderr=subprocess.STDOUT)
output = ps.communicate()[0]

Look up backquotes in bash. They capture the output of a command without it appearing to the user.
