It works fine from terminal, but when called from a thread in python, it fails.

history -d $((HISTCMD-1)) && echo 'password' | sudo -S shutdown -h 08:00

from python, here's what I did:

halt = "history -d $((HISTCMD-1)) && echo 'password' | sudo -S shutdown -h 08:00"

thread.start_new_thread(lambda: commands.getoutput(halt),())

I used lambda after trying it for other commands like opening nautilus or gedit, which works fine, but shutdown command isn't!

This:

history -d $((HISTCMD-1)) && echo 'password' | sudo -S shutdown -h 08:00

is not actually a command, it's a fragment of shell script. So you need to have the shell execute it. Something like this:

import os

halt = "history -d $((HISTCMD-1)) && echo 'password' | sudo -S shutdown -h 08:00"

os.system(halt)
