The
logger utility provides a shell command
interface to the
syslog(3)
system log module.
The options are as follows:
-
-
-f
file- Read from the specified file.
-
-
-i- Log the process ID of the logger process with each line.
-
-
-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”.
-
-
-s- Log the message to standard error, as well as the system log.
-
-
-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.

IEEE Std 1003.1-2008

The flags [

extensions to that specification.
