shmux solves a fairly simple problem that can be addressed
with a few lines of shell or Perl. This may lead you to think that using
shmux is total overkill, but shmux is a powerful tool
that offers many time and life saving features, so read on!

• When used in a script:
  
  • Ability to define what is and what is not an error for the command
    being run (based on exit code and output content)

  • Output and exit codes are saved into files to facilitate use from a
    script.
• When used interactively (directly on the command line, or from
  within a script/wrapper):
  
  • Well formatted output
    
  • Standard error output displayed in bold
    
  • Real-time status shown
    
  • Ability to pause, resume, quit cleanly
    
  • Automatically pause on error, allowing the user to cleanly stop
    before more goes wrong

  • Ability to hide output of successful targets
    
  • Mixed or un-mixed target outputs
