What is the method to view all users in linux

We can view all users under Linux by viewing the /etc/passwd file.

Use any file operation command like cat, more, less, etc. to print the user list created on the Linux system.

/etc/passwd is a text file that contains the information for each user necessary to log in to the Linux system. It saves user's useful information such as username, password, user ID, group ID, user ID information, user's home directory and shell. The

/etc/passwd file writes each user's details as one line, containing seven fields, each separated by a colon:.

The specific command is:

# cat /etc/passwd

bin:x:1:1:bin:/bin:/sbin/nologin
