Why is my bash script terminating?

  • 772

I have a node app running on my Linux hosting server.

Sometimes the app crashes and I need to restart it, so I log in and type these commands:

pkill node
cd public_html/n49900_dpndev
node server.js &

And the app runs again.

Now I would like to put this into a script so I simply need to start the script (or can execute it from a PHP script, for instance).

I created a file called "startnode":

#!/bin/bash
pkill node
cd public_html/n49900_dpndev
node server.js &

I changed the permissions with chmod 755 startnode.

But when I execute it with ./startnode it responds with:

Terminated

What do I need to do so that the commands I type in manually also work in the bash script?

    Your script name has "node" in the name and pkill node is probably killing it.

    Using pkill -x node to kill only processes whose name is exactly "node" might be more to your liking. Or even pkill -f -x "node server.js" to kill the process with the exact full command line.

  2. pkill is killing every process launched with a program with a name containing the word node even you script

    Rename you script to whatever name not containing the word node
