i run node.js in linux, from node.js how to check if a process is running from the process name ? Worst case i use child_process, but wonder if better ways ?
Thanks !
You can use the ps-node package.
https://www.npmjs.com/package/ps-node
var ps = require('ps-node');
// A simple pid lookup
ps.lookup({
command: 'node',
psargs: 'ux'
}, function(err, resultList ) {
if (err) {
throw new Error( err );
}
resultList.forEach(function( process ){
if( process ){
console.log( 'PID: %s, COMMAND: %s, ARGUMENTS: %s', process.pid, process.command, process.arguments );
}
});
});
I believe you'll be looking at this example. Check out the site, they have plenty of other usages. Give it a try.
Just incase you are not bound to nodejs, from linux command line you can also do ps -ef | grep "YOUR_PROCESS_NAME_e.g._nodejs" to check for a running process.
