DESCRIPTION
IsOn's
purpose is it to let you know when someone logs on.
IsOn
lowers it's priority automatically, so it takes very little CPU, and
spares you the trouble of remembering to use nice(1). It also puts itself
in the background automatically, as of version 4. For remote addresses
(those in dude@machine.domain format) the finger(1) utility is used, or for
a user on the same machine that you are on,
IsOn
will simply walk the utmp(5) file.
IsOn
quits when its parent is killed (logout, hangup, etc) or the
finger-cmd times out.
OPTIONS
- -a
-
Ask you for the user name, so others can't see it within ps(1) output.
- -p
-
Specify the
seconds
between iterations (defaults: local=10, remote=45).
- -i
-
Give up after
iterations
iterations (default is infinity).
- -d
-
Turn debugging mode on.
- -v
-
Turn debugging mode on.
- -j
-
Don't go in the background automatically.
- -s
-
Execute
cmd
when user is found.
- -f
-
Execute
finger-cmd
for remote adresses (default: finger -fq).
