POSTLOG(1) General Commands Manual POSTLOG(1)

postlog - Postfix-compatible logging utility



postlog [-iv] [-c config_dir] [-p
    priority] [-t tag] [text...]










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:



  

  
Read the main.cf configuration file in the named directory instead
      of the default configuration directory.

  

  
Include the process ID in the logging tag.

  

  
Specifies the logging severity: info, warn, error,
      fatal, or panic. With Postfix 3.1 and later, the program
      will pause for 1 second after reporting a fatal or panic
      condition, just like other Postfix programs.

  

  
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.

  

  
Enable verbose logging for debugging purposes. Multiple -v options
      make the software increasingly verbose.













  

  
Directory with the main.cf file.












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.



  

  
The default location of the Postfix main.cf and master.cf configuration
      files.

  

  
The list of environment parameters that a privileged Postfix process will
      import from a non-Postfix parent process, or name=value environment
      overrides.

  

  
The syslog facility of Postfix logging.

  

  
A prefix that is prepended to the process name in syslog records, so that,
      for example, "smtpd" becomes "prefix/smtpd".
