Automate Password Set And Verify

rated 0 times [ 2] [ 0] / answers: 1 / hits: 516 / 1 Year ago, sat, april 1, 2023, 4:47:36

I'm using this to set passwords in a script:

usermod -p `mkpasswd -H md5 passwordText` user

I need to create an exception in my script, just in case this command fails. What file contains the encrypted password and how do I reverse the encryption so I can verify it was written to the file correctly?

Edit: I finally found the problem with the line above. The password was allowing symbols that were being interpreted as wildcards on the command line making it appear as if the command itself failed. Nonetheless, it's lead me to new things I'm glad I know now.

Instead of reversing the the shadow- file, why not just do:

usermod -p `mkpasswd -H md5 passwordText` user



if [ $? -ne 0 ]; then

    echo "Changing password failed!!!!!!"

fi

You could replace whatever you want in the if block, but if a command ever fails for usermod it'll return a non-zero status.
