You could use  child process  module of nodejs to execute any shell commands or scripts with in nodejs  Let me show you with an example  I am running a shell script hi sh  with in nodejs   hi sh  echo  Hi There     node program js  const   exec     require  child process    var yourscript   exec  sh hi sh            error  stdout  stderr    gt                console log stdout               console log stderr               if  error     null                    console log  exec error    error                                 Here  when I run the nodejs file  it will execute the shell file and the output would be    Run  node node program js   output  Hi There    You can execute any script just by mentioning the shell command or shell script in exec callback   Hope this helps  Happy coding

you can go   var cp   require  child process      and then   cp exec    myScript sh   function err  stdout  stderr         handle err  stdout  stderr       to run a command in your  SHELL  Or go  cp spawn    myScript sh    args   function err  stdout  stderr         handle err  stdout  stderr       to run a file WITHOUT a shell  Or go  cp execFile      which is the same as cp exec   but doesn t look in the  PATH     You can also go  cp fork  myJS js   function err  stdout  stderr         handle err  stdout  stderr       to run a javascript file with node js  but in a child process  for big programs    EDIT  You might also have to access stdin and stdout with event listeners  e g    var child   cp spawn    myScript sh    args    child stdout on  data   function data         handle stdout as  data

Also  you can use shelljs plugin  It s easy and it s cross-platform   Install command   npm install  -g  shelljs   What is shellJS     ShellJS is a portable  Windows Linux OS X  implementation of Unix   shell commands on top of the Node js API  You can use it to eliminate   your shell script s dependency on Unix while still keeping its   familiar and powerful commands  You can also install it globally so   you can run it from outside Node projects - say goodbye to those   gnarly Bash scripts    An example of how it works   var shell   require  shelljs     if   shell which  git        shell echo  Sorry  this script requires git      shell exit 1         Copy files to release dir shell rm  -rf    out Release    shell cp  -R    stuff     out Release        Replace macros in each  js file shell cd  lib    shell ls    js   forEach function  file      shell sed  -i    BUILD VERSION    v0 1 2   file     shell sed  -i       REMOVE THIS LINE          file     shell sed  -i      REPLACE LINE WITH MACRO   n   shell cat  macro js    file       shell cd            Run external tool synchronously if  shell exec  git commit -am  Auto-commit    code     0      shell echo  Error  Git commit failed      shell exit 1       Also  you can use from the command line     shx mkdir -p foo   shx touch foo bar txt   shx rm -rf foo
