How to run terminal process and limit its cpu and ram usage?

[dark galleon]

Im currently working on process manager (like pm2 or smth). I need somehow run process (like python main -m) and limit its ram and cpu usage. Also would be great to change process cwd (/some/dir, python main -m).

I tried to google it, but only thing i found is how to limit the the java app itself...

That's OS dependent. You need to call specific APIs giving them the correct process ids etc

[dark galleon]

so... no crossplatform solution?

Not really no, unless there's a java library that does things like this for you

Although maybe if you use the process api you can set some priorities etc

The processbuilder api does let you set the working directory, that's a start. No priorities though

ok, process api looks kinda what i need, but i'll leave question open for some time

perhaps someone here knows a lib i need
