Logger
provides a shell command interface to the
syslog 3
system log module.
Options:
-tag -width "message"
Fl i
Log the process id of the logger process
with each line.
Fl s
Log the message to standard error, as well as the system log.
Fl f Ar file
Log the specified file.
Fl p Ar pri
Enter the message with the specified priority.
The priority may be specified numerically or as a ``facility.level''
pair.
For example, ``-p local3.info'' logs the message(s) as
info Ns rmational
level in the
local3
facility.
The default is ``user.notice.''
Fl t Ar tag
Mark every line in the log with the specified
tag .
Fl u Ar sock
Write to socket as specified with
socket
instead of builtin syslog routines.
--
End the argument list. This is to allow the
message
to start with a hyphen (-). This feature was not present in the
original BSD logger command; it is a GNU-specific extra.
Ar message
Write the message to log; if not specified, and the
f
flag is not
provided, standard input is logged.
The
logger
utility exits 0 on success, and >0 if an error occurs.
