How to pause the Jmeter run in non gui mode in linux server

I am posting data to a REST API using HTTP POST requests. The jmeter setup is single thread. As i am making 200,000 post calls i want to pause the run when needed and i want to resume the run when needed.

NOTE: i am running the jmeter in NON GUI mode on Linux server, which will not have a GUI for anything.
Other important thing is i can't program it before the run starts because i'm not sure when to pause the suit or when to resume it.
