Hands-On System Programming with Linux

Using prlimit(1) – examples

Example 1—querying limits:

$ prlimit

Output for the preceding command is as follows:

$ ps  PID TTY          TIME CMD 2917 pts/7    00:00:00 bash 3339 pts/7    00:00:00 ps$ prlimit --pid=2917RESOURCE   DESCRIPTION                             SOFT      HARD UNITSAS         address space limit                unlimited unlimited bytesCORE       max core file size                 unlimited unlimited bytesCPU        CPU time                           unlimited unlimited seconds[...]$ 

Here, we have abbreviated the output for better readability.

Example 2—set the resource limits for max file size and max stack size for the (preceding) shell process:

$ prlimit --pid=2917 --fsize=2048000 --stack=12582912 $ prlimit --pid=2917 | egrep -i "fsize|stack" ...
