How Can I List Running Processes in Go?

Enumerating Running Processes in Go

While the OS package in Go provides various functions for interacting with the operating system, it lacks a dedicated mechanism for retrieving a list of currently running processes. This absence is not arbitrary but rather aligns with the design principles of the Go language, which emphasizes simplicity and concurrency over low-level system management.

In most programming scenarios, the need to enumerate all running processes is minimal. Go programs typically prefer to operate on specific processes or a limited set of them. Moreover, the process ID (PID) of a target process is frequently obtained through alternative means rather than the need to scan the list of all processes.

On Linux systems, where the /proc filesystem provides a snapshot of running processes, it is possible to obtain the process list by parsing the files in this directory. However, this method is platform-specific and relies on the underlying operating system's implementation.
