+# ms2duration
+
+> Convert a number of milliseconds to a string duration.
+
+
+
+## Usage
+
+```javascript
+var ms2duration = require( '@stdlib/time/ms2duration' );
+```
+
+#### ms2duration( str )
+
+Converts a number of milliseconds to a string duration.
+
+```javascript
+var duration = ms2duration( 1030 );
+// returns '1s30ms'
+
+duration = ms2duration( 3600000 );
+// returns '1h'
+```
+
+
+
+
+
+
+
+## Notes
+
+- A duration string is a string containing a sequence of time units. A time unit is a non-negative integer followed by a unit identifier. The following unit identifiers are supported:
+
+ - `d`: days
+ - `h`: hours
+ - `m`: minutes
+ - `s`: seconds
+ - `ms`: milliseconds
+
+ For example, the string `1m3s10ms` is a duration string containing three time units: `1m` (1 minute), `3s` (3 seconds), and `10ms` (10 milliseconds). The string `60m` is a duration string containing a single time unit: `60m` (60 minutes).

+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var ms2duration = require( '@stdlib/time/ms2duration' );
+
+var duration = ms2duration( 1030 );
+// returns '1s30ms'
+
+duration = ms2duration( 3600000 );
+// returns '1h'
+
+duration = ms2duration( 0 );
+// returns '0ms'
+
+duration = ms2duration( 86400000 );
+// returns '1d'
+
+duration = ms2duration( 86400000+3600000+60000+1000+100 );
+// returns '1d1h1m1s100ms'
+```

+## CLI
+
+
+
+### Usage
+
+```text
+Usage: ms2duration [options] []
+
+Options:
+
+ -h, --help Print this message.
+ -V, --version Print the package version.
+ --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 $'3000\n25300' | ms2duration --split /\r?\n/
+
+ # Escaped...
+ $ echo -n $'3000\n25300' | ms2duration --split /\\r?\\n/
+ ```
+
+- The implementation ignores trailing delimiters.
+
+
+
+
+
+
+
+### Examples
+
+```bash
+$ ms2duration 1000
+1s
+```
+
+To use as a [standard stream][standard-streams],
+
+```bash
+$ echo -n '1000\n2000' | ms2duration
+1s
+2s
+```
+
+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 '1350,2000' | ms2duration --split ','
+1s350ms
+2s
+```
