Show pm2 command that started a process

Question

From my linux machine, typing pm2 status shows me

│ App name     │ id │ mode │ pid   │ status  │ restart │ uptime │ memory      │ watching │
├──────────────┼────┼──────┼───────┼─────────┼─────────┼────────┼─────────────┼──────────┤
│ gamatrix-dev │ 0  │ fork │ 0     │ stopped │ 0       │ 0      │ 0 B         │ disabled │
│ gamatrix     │ 1  │ fork │ 22779 │ online  │ 10      │ 2D     │ 78.793 MB   │ disabled │
│ elevacad     │ 2  │ fork │ 14106 │ online  │ 13      │ 3D     │ 36.227 MB   │ disabled │

I'm pretty sure for the last two lines, they were initiated by a command like pm2 start someapp.js. Is there a way to know what value someapp.js really was that started the process?

Answer 1

As mentioned in a comment, use

pm2 describe

That will produce copious output similar to the following:

The interpreter, interpreter args, script path and script args should give you what you are after. See also this answer to a similar question.
