Answer 1

On the Linux working framework, you'll basically check the data of any client from remote or nearby command line interface. That's ‘finger’ command.

syntax : finger -option user user@host

-s : isplays the user's login name, genuine title, terminal title and type in status (as a "*" after the terminal title on the off chance that type in authorization is denied), sit still time, login time, office area and office phone number.

-l : Produces a multi-line arrange showing all of the data portrayed for the -s choice as well as the user's domestic catalog, domestic phone number, login shell, mail status, and the substance of the records ".arrange", ".extend", ".pgpkey" and ".forward" from the user's domestic registry.

-p : Anticipates the -l choice of finger from showing the substance of the ".arrange", ".venture" and ".pgpkey" records.

-m : Avoid coordinating of usernames. The client is as a rule a login title; be that as it may, coordinating will moreover be done on the users' genuine names, unless the -m alternative is provided. All title coordinating performed by finger is case harsh.

Example :

finger -p HomeworkLib

Show data about the user HomeworkLib Output will show up similar to the following:
