There are several ways to limit the memory usage for commands in Linux. Here are a few examples:
- Using the
ulimitcommand: Theulimitcommand can be used to set limits on various system resources, including memory usage. For example, to limit the memory usage for a command to 256MB, you can use the following command:
ulimit -v 256000
- Using the
cgroupsfeature: cgroups is a Linux kernel feature that allows for the limitation and prioritization of system resources, including memory. To limit the memory usage for a command to 256MB, you can use the following commands:
sudo cgcreate -g memory:mygroup
sudo cgset -r memory.limit_in_bytes=256000000 mygroup
sudo cgexec -g memory:mygroup <command>
- Using
systemd-run: You can use thesystemd-runcommand to launch a command with a specific memory limit. For example, to limit the memory usage for a command to 256MB, you can use the following command:
systemd-run --scope --slice=memory-limited -p MemoryLimit=256M <command>
It's worth noting that the above examples are just a few possibilities and you might have to adapt the command to your specific use case.
