@MomsFriendlyDevCo/CLI-Snip

A less irritating version of the GNU cut utility.

Features:

  • Automatically uses a delimiter which cuts via spaces, tabs and commas
  • RegExp compatible delimiters
  • Can support complex field specifications - * X X..Y X-Y X~Y <X <=X >X >=X
  • Can trim input lines
  • (Mostly) backwards compatible with the regular cut command
  • --verbose mode to see what the tool is actually doing

Installation

Install via NPM in the usual way:

npm i -g @momsfriendlydevco/cli-snip

(You may need a sudo prefix depending on your Node setup)

Usage

Usage: snip [-f fields] [-d delimiter]

Options:
  -V, --version                    output the version number
  -d, --delimiter [chars]          Specify the column delimiter (default:
                                   "/[\\t\\s,]/")
  -f, --fields [field-list]        Specify the fields to output (default is
                                   '*') (default: "*")
  -u, --undefined [string]         What to output when a field value cannot be
                                   found or is falsy (default is an empty
                                   string) (default: "")
  -j, --output-delimiter [string]  Delimiter to use between output fields
                                   (default is a space) (default: " ")
  -v, --verbose                    Output information about the parsed command
                                   line options
  --debug                          Show advanced debugging information per-line
                                   processed
  --trim                           Trim all input lines (default is enabled,
                                   use --no-trim to disable) (default: true)
  --max [number]                   Specify the highest field index to use when
                                   using higher-than ranged fields (e.g. ">3")
  -h, --help                       output usage information

Notes:
  * If delimiter is surrounded by "/" marks its parsed as a RegExp
  * The default delimiter is any space, tab or comma - '/[\s\t,]/'
  * Field ranges can be of the form: X X..Y X-Y X~Y <X <=X >X >=X
  * Input files can be read from specified files or from STDIN if non are specified

Examples:

  # Parse input as a CSV and output only the first field
  snip -d, -f1 <input

  # Cut up input using any space character (as a RegExp) and output fields 1, 2 and 5 to 9
  snip -d '/s/' -f1,2,5-9 <input
