To search for multiple users in the /etc/passwd file, you can use the grep command with a regular expression. Here's an example command that searches for users 'joker' and 'batman':
sudo grep -E '^(joker|batman):' /etc/passwd
Breakdown:
sudo: Runs the command with superuser privileges.grep: The command used for searching text.-E: Enables extended regular expressions, allowing the use of the|operator for "or".^(joker|batman):: This pattern matches lines that start with either 'joker' or 'batman', followed by a colon, which is the format used in the/etc/passwdfile.
You can add more usernames by extending the pattern within the parentheses, separated by the | operator.
