Mailutils logger
The mailutils logger tool logs information using Mailutils log facility.
Syntax:
mailutils logger [options] [message]
The message argument, if supplied, gives the text to log. If not supplied, the utility reads lines of text from standard input or a file (if the --file option is given) and sends them to log:
# Send text to log $ mailutils logger I am here # Log each line from file.txt $ mailutils logger --file file.txt # Read stdin and log it: $ mailutils logger
The default logging channel is bound to standard error. To bind it to syslog, use the --syslog command line option. In that case mailutils uses facility user and priority err. You can change this by using the --priority (-p) option. Its argument is either a syslog facility name or facility and severity names separated by a dot. Thus, the following invocation will use facility auth, severity info:
mailutils logger --priority auth.info
The syslog tag can be set using the --tag (-t) option:
mailutils logger --tag myprog
The default tag is mu-logger.
The --severity (-s) option sets the Mailutils severity level. Its argument can be any of the following strings: debug, info, notice, warning, error, crit, alert, emerg.
Finally, the --locus (-l) option binds log messages to a location in a file. Its argument has the following syntax:
file:line[.col][-[file:]line[.col]]
where file is the file name, line is the line number and optional col is the column number in that file.
For example, the following invocation:
mailutils logger --locus mailutils.rc:34 Suspicious statement
will send the following to the log:
mailutils-logger: mailutils.rc:34: Suspicious statement
