Python script to manually install binaries

I needed ack and prename installed in the system bin, along with some of my own. So I cleaned up the code and decided to share. This only requires vanilla python v3+.

What it does:

1. For each item in the dictionary _scripts - If script is missing , or older than a week (can be changed on line 27), it will download it from the url defined in the dictionary item
2. For each *.sh or *.pl file in the script's directory - Copies it to /usr/bin/ and enables execution permission

Python Script

import os
import subprocess

from datetime import datetime
from datetime import timedelta

def shell(cmd, check=False) -> str:
    res = subprocess.run(cmd, stdout=subprocess.PIPE, shell=True, check=check)
    return res.stdout.decode('utf-8').strip()


def curl(url, scriptName):
	shell(f'curl {url} -o {scriptName}')


_scripts = {
	#https://forums.unraid.net/topic/79490-rename-instead-of-rename-perl-instead-of-unix-util/
	'prename.pl': lambda k: curl('https://gist.githubusercontent.com/javiermon/3939556/raw/b9d0634f2c099b825a483d3d75cae1712fb9aa31/prename.pl', k),
	#https://beyondgrep.com/install/
	'ack.pl': lambda k: curl('https://beyondgrep.com/ack-v3.5.0', k)
}

_scriptExt = ['.sh', '.pl']
_bin = '/usr/bin/'

def run():
	oneWeekAgo = datetime.now() - timedelta(days=7)
	for k in _scripts.keys():
		sp = './' + k
		if not os.path.exists(sp) or datetime.fromtimestamp(os.path.getmtime(sp)) < oneWeekAgo:
			print(f'Updating: {k}')
			_scripts[k](k)

	for f in os.listdir(os.fsencode('./')):
		fn = os.fsdecode(f)
		fns = os.path.splitext(fn)
		if fns[1] in _scriptExt:
			print(f'Copying: {fn} -> {_bin}{fns[0]}')
			shell(f'cp {fn} {_bin}{fns[0]}')
			shell(f'chmod +x {_bin}{fns[0]}')

run()

Bash Script

• I suggest adding to UserScripts with Schedule set to "At First Array Start Only"
• Change "/mnt/user/projects/scripts" to wherever you save the python script
• Change "installScripts.py" to whatever you name the python script

#!/bin/bash

cd /mnt/user/projects/scripts
python3 installScripts.py
