ulimit – Control the resources available to processes
ulimit, Bash Built-in Command, provides control over the
resources (Virtual Mem, Max no .of process, Core file
size, …) available to processes started by the shell.
If Max no. of user process is set to 5, then the particular
user can’t run more then 5 process.
$ ulimit -a — Show All current limits.
$ ulimit -c — Show core file size (If Core file size is 0, Core file will not be created during the SEG fault).
$ ulimit -c 1000 — Set new core file size.
$ ulimit -u 3 — Set max no .of user processes
$ ulimit -n — Show max open files.
