.TH "NPM\-RUN\-SCRIPT" "1" "March 2015" "" "" .SH "NAME" \fBnpm-run-script\fR \- Run arbitrary package scripts .SH SYNOPSIS .P .RS 2 .nf npm run\-script [command] [\-\- ] npm run [command] [\-\- ] .fi .RE .SH DESCRIPTION .P This runs an arbitrary command from a package's \fB"scripts"\fR object\. If no \fB"command"\fR is provided, it will list the available scripts\. \fBrun[\-script]\fR is used by the test, start, restart, and stop commands, but can be called directly, as well\. When the scripts in the package are printed out, they're separated into lifecycle (test, start, restart) and directly\-run scripts\. .P As of \fBnpm@2\.0\.0\fR \fIhttp://blog\.npmjs\.org/post/98131109725/npm\-2\-0\-0\fR, you can use custom arguments when executing scripts\. The special option \fB\-\-\fR is used by getopt \fIhttp://goo\.gl/KxMmtG\fR to delimit the end of the options\. npm will pass all the arguments after the \fB\-\-\fR directly to your script: .P .RS 2 .nf npm run test \-\- \-\-grep="pattern" .fi .RE .P The arguments will only be passed to the script specified after \fBnpm run\fR and not to any pre or post script\. .P The \fBenv\fR script is a special built\-in command that can be used to list environment variables that will be available to the script at runtime\. If an "env" command is defined in your package it will take precedence over the built\-in\. .SH SEE ALSO .RS 0 .IP \(bu 2 npm help 7 scripts .IP \(bu 2 npm help test .IP \(bu 2 npm help start .IP \(bu 2 npm help restart .IP \(bu 2 npm help stop .RE
