logger – make entries in the system log
SYNOPSIS
logger [-cis] [-f file] [-p pri] [-t tag] [message ...]
DESCRIPTION
The logger utility provides a shell command interface to the syslog(3) system log module.
The options are as follows:
- -c

If unable to pass the message to syslogd(8), attempt to write the message to the console.
- -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.
EXIT STATUS
