You can specify login or logout events to monitor by setting the
watch variable. Normally, this is done by specifying a list of
% watch=( pfalstad subbarao sukthnkr egsirer )
log command reports all people logged in that you are
% log pfalstad has logged on p0 from mickey. pfalstad has logged on p5 from mickey. % ... subbarao has logged on p8 from phoenix. % ... subbarao has logged off p8 from phoenix. % ... sukthnkr has logged on p8 from dew. % ... sukthnkr has logged off p8 from dew.
If you specify hostnames with an @ prepended, the shell will watch for all users logging in from the specified host.
% watch=( @mickey @phoenix ) % log djthongs has logged on q2 from phoenix. pfalstad has logged on p0 from mickey. pfalstad has logged on p5 from mickey.
If you give a tty name with a % prepended, the shell will watch for all users logging in on that tty.
% watch=( %ttyp0 %console ) % log root has logged on console from . pfalstad has logged on p0 from mickey.
The format of the reports may also be changed.

If you have a `.friends' file in your home directory, a convenient way to make zsh watch for all your friends is to do this:
% watch=( $(< ~/.friends) ) % echo $watch subbarao maruchck root sukthnkr ...
watch is set to
all, then all users logging in or out
will be reported.
