password= Assignment to a shell variable $() call to a subprocess perl -e call the perl binary to execute code from command line, instead of file source code 'print crypt($ARGV[0], "password")' display the result of calling the perl function crypt crypt($ARGV[0], "password") crypt will return a digest of whatever was given as argument. $ARGV[0] is the first argument from the command line, in this case the last $password term. "password" is what's called SALT string. It can be anything. Not to confuse with $password $password Argument given at the command line, in the form of perl variable, to crypt (presumably a string that represents a clear text password)
Best way of learn is to try:
Change password and random_text to anything you want

Hello, I am quite new to linux and was wondering what this line of code did?
Thank you very much!
Another solution is to use openssl to generate encrypted passwords (it automatically chooses salt values for you, but you could duplicate what the perl code was doing by usint the -salt pa option
Notice how the $password variable is quoted above, this is to protect against white space in the password.
