Iam a new Linux system administrator and I’m unable to find the command to list all users on my Linux server. What is the command to list users under Linux operating systems? How do I list users in Linux?

The /etc/passwd file contains one line for each Linux user account, with seven fields delimited by colons. This is a text file. You can easily list users under Linux using the cat command or other commands such as grep command/egrep command and more. This page describes various Linux commands to list all users on the Linux operating system, including Ubuntu, Debian, RHEL, Arch, Fedora, CentOS, and other distros.
