Please provide more input as to what exactly you want to do with the output of "finger" command. May be it'll help us to think of an alternate solution.

You can do a line by line parsing using awk or perl.

For e.g. finger | awk 'NR==1 {print}' would print just the first line from the output of finger equivalent to finger | head -1

You could do x=`finger` to get the entire output of finger in variable 'x'

SAFE_FINGER(8)						     Linux Programmer's Manual						    SAFE_FINGER(8)

NAME

       safe_finger - finger client wrapper that protects against nasty stuff from finger servers

SYNOPSIS

       safe_finger [finger_options]

DESCRIPTION

       The  safe_finger  command  protects  against nasty stuff from finger servers. Use this program for automatic reverse finger probes from the
       tcp_wrapper (tcpd) , not the raw finger command. The safe_finger command makes sure that the finger client is not run with root privileges.
       It  also  runs  the finger client with a defined PATH environment.  safe_finger will also protect you from problems caused by the output of
       some finger servers. The problem: some programs may react to stuff in the first column. Other programs may get upset by thrash anywhere	on
       a  line.  File  systems may fill up as the finger server keeps sending data. Text editors may bomb out on extremely long lines.	The finger
       server may take forever because it is somehow wedged.  safe_finger takes care of all this badness.
