If you don't mind can you explain this a bit to me?
When i use finger for a user id i get back a login and a name in the first row (with gaps in between).
With head -1 i want to hold only this first row and with getline i save this row into a variable. What's going wrong with it?

I mean why it's the same pipe if we change every time $1? Are you saying that finger was ok in addition to the last pipe along with getline?

Name
       finger - print user finger information

Syntax
       finger [options] [name...]

Description
       By  default,  lists  the login name, full name, terminal name and write status, idle time, login time, and office location and phone number
       for each current ULTRIX user.  Terminal write status is noted as an asterisk (*) before the terminal name if write  permission  is  denied.
       Idle  time is given in minutes if the listing shows a single integer, hours and minutes if a colon (:) is present, or days and hours if a d
       is present.

       A longer format also exists and is used by whenever a list of people's names is given.  (Account names as well as first and last  names	of
       users  are  accepted.) This format is multi-line, and includes all the information described above as well as the user's home directory and
       login shell.  Additionally, it displays the information contained in the files .plan and .project, both of which are located in the  user's
       home directory.	If no list is given, all the people currently logged in are shown.

       The  command  may  be used to look up users on a remote machine.  The format is to specify the user as user@host.  If the user name is left
       off, the standard format listing is provided on the remote machine.

Options
       -b   Displays a briefer long form list of users.

       -f   Disables printing of headers for short and quick outputs.

       -h   Suppresses printing of the .project file.

       -i   Displays list of users with idle times.

       -l   Displays output in long format.

       -m   Matches arguments only on user name.

       -p   Suppresses printing of the .plan file.

       -q   Displays list of users.

       -s   Displays output in short format.

       -w   Displays narrow short format of specified users.

Restrictions
       Only the first line of the .project file is printed.

       The user's or file cannot be a link to another file.  If either of these files is something other than a regular file, it will be ignored.

Files
       Who file

       User information

       Last login times

       Plans

       Projects
