node.js - How do I write a shell script using node to run multiple javascript files one after the other? -

i want write .sh file run multiple javascript files.

i know need following lines:

#!/usr/bin/env node chmod u+x ./a/file1.js ./a/file2.js

is correct put 2 .js files 1 after other? need file1.js execute first , file2.js because of functions file2.js need information outputted file1.js.

i'm bit confused difference between #!/usr/bin/env node , #!/usr/bin/env bash. still able run .js files bash?

#!/usr/bin/env node sets environment node.js javascript environment.

for example if create simple script test.js following content:

#!/usr/bin/env node  // we're in javascript! var d = new date();  console.log('current time: ' + d);

afterwards make executable:

$ chmod u+x test.js

then can execute in shell:

$ test.js current time: sun nov 13 2016 07:14:15 gmt+0000 (gmt)

the file extension doesn't matter:

$ mv test.js test.sh $ test.sh current time: sun nov 13 2016 07:15:05 gmt+0000 (gmt)

if don't want change javascript files become shell scripts can run them shell script using node.

tasks.sh:

#!/bin/sh node ./a/file1.js node ./a/file2.js

afterwards make executable , run it:

$ chmod u+x tasks.sh $ tasks.sh
