NAME

App::Unliner - Untangle your unix pipeline one-liners

SYNOPSIS

Unliner is a scripting language and toolset for refactoring and developing unix one-liners.

Note: This page is a high-level overview of unliner. For an introduction and manual, see App::Unliner::Intro.

The simplest way to install unliner is with cpanminus:

            

              
              
curl -sL https://raw.github.com/miyagawa/cpanminus/master/cpanm | sudo perl - App::Unliner
            
          

Here is an unliner script to display response code tallies from standard apache logs. Save it in the file reportgen:

            

              
              
#!/usr/bin/env unliner
def main {
    extract-response-codes $@ | tally
}
def extract-response-codes : perl -n {
    ## HTTP response code is 2nd last field
    print "$1\n" if /(\d\d\d) \S+$/;
}
def tally {
    sort | uniq -c | sort -rn
}
            
          

Now make reportgen executable:

            

              
              
$ chmod a+x reportgen
            
          

Now you can run reportgen like a normal program:

            

              
              
$ ./reportgen /var/www/log/access.log
  43628 200
   1911 301
    201 404
      6 500
