prlimit

Get and set process resource limits.

Reads limits using getrlimit(2) for the current process, or /proc/<pid>/limits for other processes. Sets limits using setrlimit(2) for self or prlimit(2) for other PIDs (requires CAP_SYS_RESOURCE).

Resource flags (--core, --nofile, etc.) accept an optional =limit value in soft:hard, soft:, :hard, or plain value format (use unlimited for no limit). Without =limit, the flag selects that resource for display only.
