CLI

Usage

Usage: remove-last [options] [<string>]

Options:

  -h,    --help                Print this message.
  -V,    --version             Print the package version.
         --n                   Number of characters to remove. Default: 1.
         --split sep           Delimiter for stdin data. Default: '/\\r?\\n/'.

Notes

If the split separator is a regular expression, ensure that the split option is either properly escaped or enclosed in quotes.

# Not escaped...
$ echo -n $'beep\nboop' | remove-last --split /\r?\n/

# Escaped...
$ echo -n $'beep\nboop' | remove-last --split /\\r?\\n/

The implementation ignores trailing delimiters.

Examples

$ remove-last beep
bee

To use as a standard stream,

$ echo -n 'beep\nboop' | remove-last --n 2
be
bo

By default, when used as a standard stream, the implementation assumes newline-delimited data. To specify an alternative delimiter, set the split option.

$ echo -n 'beep\tboop' | remove-last --split '\t'
bee
boo
