logger
provides a shell command interface to the
syslog(3)
system log module.
Options:
-i
Log the process id of the logger process
with each line.
-s
Log the message to standard error, as well as the system log.
-f file
Log the specified file.
-p 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
informational
level in the
local3
facility.
The default is ``user.notice.''
-t tag
Mark every line in the log with the specified
tag.
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.
