# removeLast
> Remove the last character(s) of a string.
## Usage
```javascript
var removeLast = require( '@stdlib/string/remove-last' );
```
#### removeLast( str\[, n] )
Removes the last character of a `string`.
```javascript
var out = removeLast( 'last man standing' );
// returns 'last man standin'
out = removeLast( 'Hidden Treasures' );
// returns 'Hidden Treasure'
```
If provided a second argument, the function removes the last `n` characters.
```javascript
var out = removeLast( 'foo bar', 4 );
// returns 'foo'
out = removeLast( 'foo bar', 0 );
// returns 'foo bar'
```
## Examples
```javascript
var removeLast = require( '@stdlib/string/remove-last' );
var str = removeLast( 'last man standing' );
// returns 'last man standin'
str = removeLast( 'presidential election' );
// returns 'presidential electio'
str = removeLast( 'javaScript' );
// returns 'javaScrip'
str = removeLast( 'Hidden Treasures' );
// returns 'Hidden Treasure'
str = removeLast( 'Lorem ipsum dolor sit amet', 4 );
// returns 'Lorem ipsum dolor sit '
str = removeLast( '🐮🐷🐸🐵', 2 );
// returns '🐮🐷'
```

## CLI
### Usage
```text
Usage: remove-last [options] []
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][mdn-regexp], ensure that the `split` option is either properly escaped or enclosed in quotes.
```bash
# 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
```bash
$ remove-last beep
bee
```
To use as a [standard stream][standard-streams],
```bash
$ echo -n 'beep\nboop' | remove-last --n 2
be
bo
```
By default, when used as a [standard stream][standard-streams], the implementation assumes newline-delimited data. To specify an alternative delimiter, set the `split` option.
```bash
$ echo -n 'beep\tboop' | remove-last --split '\t'
bee
boo
```
