POSTLOG(1)						      General Commands Manual							POSTLOG(1)

NAME
postlog - Postfix-compatible logging utility SYNOPSIS
postlog [-iv] [-c config_dir] [-p priority] [-t tag] [text...] DESCRIPTION
The postlog(1) command implements a Postfix-compatible logging interface for use in, for example, shell scripts. By default, postlog(1) logs the text given on the command line as one record. If no text is specified on the command line, postlog(1) reads from standard input and logs each input line as one record. Logging is sent to syslogd(8); when the standard error stream is connected to a terminal, logging is sent there as well. The following options are implemented: -c config_dir Read the main.cf configuration file in the named directory instead of the default configuration directory. -i Include the process ID in the logging tag. -p priority Specifies the logging severity: info (default), warn, error, fatal, or panic. -t tag Specifies the logging tag, that is, the identifying name that appears at the beginning of each logging record. A default tag is used when none is specified. -v Enable verbose logging for debugging purposes. Multiple -v options make the software increasingly verbose. ENVIRONMENT
MAIL_CONFIG Directory with the main.cf file. CONFIGURATION PARAMETERS
The following main.cf parameters are especially relevant to this program. The text below provides only a parameter summary. See postconf(5) for more details including examples. config_directory (see 'postconf -d' output) The default location of the Postfix main.cf and master.cf configuration files. syslog_facility (mail) The syslog facility of Postfix logging. syslog_name (see 'postconf -d' output) The mail system name that is prepended to the process name in syslog records, so that "smtpd" becomes, for example, "postfix/smtpd". SEE ALSO
postconf(5), configuration parameters syslogd(8), syslog daemon LICENSE
The Secure Mailer license must be distributed with this software. AUTHOR(S) Wietse Venema IBM T.J. Watson Research P.O. Box 704 Yorktown Heights, NY 10598, USA POSTLOG(1)
