w: Display information without including the header.

$ w --no-header

try on your machine

The command "w --no-header" is used to display information about currently logged-in users on a system without showing the header line that usually appears at the top of the output.

The "w" command is a built-in command in Unix-like operating systems (like Linux) that provides information about the system users. By default, when you run the "w" command, it displays a table-like output that includes various details such as the username, terminal name, remote host, login time, idle time, JCPU (total CPU time used by the user), PCPU (CPU time used by the specific process associated with the user), and the command being executed.

However, when you add the option "--no-header" to the "w" command, it excludes the header line from the output. The header line typically contains labels for each column, providing a description of the information displayed in the table.

Running "w --no-header" will still show the user information in a tabular format, but without the header line. This can be useful if you need to extract or process the information without the additional header information.
