Listing users in a Linux system is a very common task. 

Here at Fixwebnode, we shall look into the different commands to list users in Linux and their respective options.

Commands To List Users includes:

1. cat /etc/passwd

The "cat" command is used to display the contents of a file. The "/etc/passwd" file contains a list of users and is used to list all users in the system. To use this command, open the terminal and type "cat /etc/passwd'. This will display a list of users in the system.

2. getent passwd

The "getent" command is used to query the system's database for information about users. To use this command, open the terminal and type "getent passwd". This will display a list of users in the system.

3. cut -d: -f1 /etc/passwd

The "cut" command is used to extract specific fields from files. The "-d" option specifies the delimiter used to separate fields in a file. The "-f1" option specifies the field to extract. In this case, the "/etc/passwd" file is used and the "-f1" option specifies to extract the first field which contains the username. To use this command, open the terminal and type "cut -d: -f1 /etc/passwd'. This will display a list of users in the system.

4. awk -F: '{print $1}' /etc/passwd

The "awk" command is used to process text files. The "-F" option specifies the delimiter that should be used to separate fields in a file. To use this command, open the terminal and type "awk -F: '{print $1}' /etc/passwd". This will display a list of users in the system.
