loggerclones

The nix logger command reimplemented in portable scripting languages without any legacy 1024-byte message-size restriction.

Python

• Uses Python's standard logging module
• Differences with modern logger command:
  • Has no 1024-byte message-size restriction (no message splitting performed)
  • Supports new --ppid option to append parent process id to tag
  • Does not support --stderr option
• Similarities with modern (Fedora util-linux) logger command:
  • Accepts log message as command-line arguments
  • Accepts log messages via stdin
  • Accepts log messages by reading file passed to -f / --file
  • Single-letter opts and full-word opts are completely compatible
  • Supports specifying custom facility.priority
  • Supports sending to custom socket, local/remote tcp & udp
  • Supports custom tags
  • Supports adding PID to tag
  • Supports adding custom (arbitrary) ID to tag

Tested on

• Fedora
• RHEL 7
• RHEL 6 (install python-argparse package)

$ ./logger.py -h
usage: logger.py [-h] [-p PRIO] [-t TAG] [-i | --id [ID] | --ppid]
                 [-u SOCKET | -d | -T] [-n SERVER] [-P PORT] [-f FILE] [-e]
                 [MESSAGE [MESSAGE ...]]

A python logger clone that reads input from stdin, cmdline, or files

positional arguments:
  MESSAGE              log single MESSAGE and quit instead of reading stdin
                       (default: None)

optional arguments:
  -h, --help           show this help message and exit
  -p, --priority PRIO  specify priority for given message (default: user.info)
  -t, --tag TAG        add tag to given message (default: rsaw)
  -i, --pid            append logger.py PID to tag (default: False)
  --id [ID]            append arbitrary ID to tag or if no ID specified, use
                       PID (default: None)
  --ppid               append logger.py parent PID to tag (default: False)
  -u, --socket SOCKET  write to local UNIX socket (default: /dev/log)
  -d, --udp            log via UDP instead of UNIX socket (default: False)
  -T, --tcp            log via TCP instead of UNIX socket (default: False)
  -n, --server SERVER  DNS/IP of syslog server to use with --udp or --tcp
                       (default: localhost)
  -P, --port PORT      port to use with --udp or --tcp (default: 514)
  -f, --file FILE      log each line of FILE as a separate message instead of
                       reading stdin or specifying MESSAGE on cmdline
                       (default: None)
  -e, --skip-empty     ignore empty lines when using --file (default: False)
