Running bash script without asking for password

bashpasswordterminal

I wrote a little shell script that switches some settings that I have to switch a lot. I saved it as a .command file, so double-clicking will run it. Now everytime I run it, it's asking for my password (although just changing those settings doesn't require any password when I do it by hand).
Is it possible to make the bash script run, without it asking for a password everytime? All it does is switches my proxy settings off…

The script:

#!/bin/bash
osascript -e 'quit app "MyAppsAnywhere"'
networksetup -setautoproxystate Wi-Fi off
exit 0

Best Answer

You could use

sudo networksetup -setautoproxystate Wi-Fi off

and then configure sudoers(5) to allow that exact command (or any networksetup invocation (or any command whatsoever)) without a password, though this generally requires fiddling around with visudo(8) and if you get things wrong may lock you out of future use of sudo(1). Open a root shell, make a backup of /etc/sudoers, edit the file by running visudo, test it, and use root shell to restore the backup of the config if things go awry. Relevant sudoers(5) config lines would be along the lines of

# only with these args
yourloginnamehere ALL=(root) NOPASSWD: /usr/sbin/networksetup-setautoproxystate Wi-Fi off, /usr/sbin/networksetup-setautoproxystate Wi-Fi on

# any arguments to the command
yourloginnamehere ALL=(root) NOPASSWD: /usr/sbin/networksetup

# no password prompts at all from sudo ever
yourloginnamehere  ALL=(ALL) NOPASSWD: ALL

Also visudo may run a strange editor by default, so you might want to read up on the EDITOR and DISPLAY environment variables and related sudo questions and documentation before you get stuck in vi...

MacOS – Automatically quit Terminal when typing exit

The approach given here looks a little simpler—maybe it would work for you?

If you don't want to remember to type "quit" instead of "exit", and you're using bash, just add the following to your .bashrc or other shell startup script:
trap '/usr/bin/osascript -e "tell application \"terminal\" to quit"' 0
What's it do? When the shell receives signal 0 (zero), that is, told to exit, it will execute this command as the last thing it does. This allows your shell, etc, to exit gracefully, and asking Terminal.app to exit via applescript makes sure it does the same. In other words, type 'exit', and your shell exits, then Terminal quits, all cleanly and the way nature intended.

MacOS – OSX asking for the password

As you phrased this, it generally occurs because the login password was reset at some point, and now the "login" keychain is protected with a different password than the account as a whole. The other possibility is that the keychain is set to lock automatically. Both issues can be addressed using Keychain Access, which lives in your Utilities folder.
