Readme
last
Return the last character(s) of a string.
Installation
To use as a general utility, install the CLI package globally
npm install -g @stdlib/string-last-cli
Usage
Usage: last [options] [<string>]
Options:
-h, --help Print this message.
-V, --version Print the package version.
--n num Number of characters to return. Default: 1.
--split sep Delimiter for stdin data. Default: '/\\r?\\n/'.
--mode mode Type of character to return. Default: 'grapheme'.
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' | last --split /\r?\n/ # Escaped... $ echo -n $'beep\nboop' | last --split /\\r?\\n/
The implementation ignores trailing delimiters.
Examples
$ last beep
p
To use as a standard stream,
$ echo -n 'beep\nboop' | last --n=2
ep
op
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' | last --split '\t'
p
