Pm2: Namespace and pattern matching `delete` command arguments

[hadrien-toma]

What's going wrong?

Nothing, really! This is a feature request for a use case that causes me trouble, maybe you will tell me that there is a better way to achieve the wanted behavior and I will thank you for that! What I want is to be able to use namespace for the arguments of the pm2 delete command.
Basically, I would like to be able to do:

pm2 start --name foo_1 app.js
pm2 start --name foo_2 app.js
pm2 start --name bar_1 app.js
pm2 delete foo_*

Supporting information

Please run the following command (available on PM2 >= 2.6)

$ pm2 report

You just need to use slash : pm2 delete /foo.*/ :)

Alright, amazing :smile:! Thank you very much! May I ask you if you can point me to some documentation to help me understand why this works? :confused:

@hadrien-toma when the "name" given starts and ends with a /, it's detected as a regular expression. source.

Exactly what I wanted, thank you both!
