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
splitoption 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
