Is it possible to limit or set a resource usage cap for a program when it is launched in Linux?

Yes, in Linux, it is possible to limit the resources available to a program using the ulimit utility or system mechanisms such as cgroups.

• ulimit allows setting limits on memory usage, CPU, open files, and more. For example:

ulimit -v 500000  # limit virtual memory to 500000 KB
./your_program

• cgroups (control groups) are a more powerful tool for limiting CPU, memory, disk, and network at the process group level. They are used in containers and high-load systems.

Thus, when launching a program, you can set restrictions to prevent excessive resource consumption.
