How to make a Bash Script take user input for Changing a Password

Question

The following command on OSX will change an Open Directory (Apple's LDAP) password. The $ is the prompt:

$ dscl -u diradmin -P 'password' /LDAPv3/127.0.0.1 passwd /Users/username newpassword 

I would love to turn this into an interactive shell script of some sort (let's call it 'odpasswd') that first prompts the admin for the username whose account they want to change passwords for, then for the password, along these lines:

$ odpasswd $ Username you'd like to change passwords for? johnd $ New Password? secretpassword $ Done! Password changed successfully for username 'johnd' to 'secretpassword' 

I'm not enough of a shell script expert to know how to turn this into something like this.

Your help is always much appreciated! Thanks!

Answer 1

You could define variables for the -P "$password". Also read about 'read' function in bash.

$ dscl -u diradmin -P 'password' /LDAPv3/127.0.0.1 passwd /Users/username newpassword

This is an untested script, but you could figure it out.

#!/bin/bash read -p "For which user to change the password? " username read -s "Enter the old password for $username " oldpassword read -s "Enter the new password for $username " newpassword dscl -u diradmin -P "$oldpassword" /LDAPv3/127.0.0.1 passwd /Users/"$username" "$newpassword"
