You can try the code below found here – didn’t try it but it looks promising:
run BASH built-in commands in Python

from subprocess import Popen, PIPE, STDOUT shell_command = 'bash -i -c "history -r; history"' event = Popen(shell_command, shell=True, stdin=PIPE, stdout=PIPE, stderr=STDOUT) output = event.communicate()

@Hugo: I am on the fence about where to put this function. Right now I keep it in my ~/.bashrc. If it were any longer, I would likely pull it out into my directories of personal scripts, symlinked somewhere system-appropriate.

The alias commands I would definitely keep in ~/.bashrc, so that all my defined aliases are in one intuitive place.

Lovely!

Rookie question, sorry:

Do you suggest to put that function in ~/.bashrc ? Or rather as a separate script in ~/bin ?

And the what about the *alias* commands?

I wanted to steer clear of just using .bash_history because that doesn’t take into account the format and other options declared in .bashrc and .bash_profile, as the history builtin does. So if you filter out certain commands, or do anything else custom, the file won’t reflect that, which seemed sub-optimal to me.

Sorry but I managed to blow the post, here we go again:

import os

def do_history():
h = open(‘%s/.bash_history’ % os.environ['HOME'])
counter = 0
for line in h.readlines():
counter += 1
print counter, line.replace(‘\n’,”)

if __name__ == ‘__main__’:
do_history()

AFAIK history just prints the contents of ~/.bash_history and it's line number, so you could write that in python, a very quick and dirty solution: import os def do_history(): h = open('%s/.bash_history' % os.environ['HOME']) counter = 0 for line in h.readlines(): counter += 1 print counter, #!/usr/bin/python import os def do_history(): h = open('%s/.bash_history' % os.environ['HOME']) counter = 0 for line in h.readlines(): counter += 1 print counter, line.replace('\n','') if __name__ == '__main__': do_history()
