Some times we need our application to create core dump when it crashes during development. You can easily enable this using “ulimit -c unlimited”.
To enable core dump in a terminal, you have to set the core file size variable. When this variable is set to zero, core dump is not created for a crashed application. This variable specifies the maximum size of a core dump file. You can check the value of this variable by using the command: ‘ulimit -a’
➜ ~ ulimit -a
-t: cpu time (seconds) unlimited -f: file size (blocks) unlimited -d: data seg size (kbytes) unlimited -s: stack size (kbytes) 8192 -c: core file size (blocks) 0 => Variable to consider -v: address space (kbytes) unlimited -l: locked-in-memory size (kbytes) unlimited -u: processes 709 -n: file descriptors 256 ➜ ~
To set core file size, you can use the following command: ‘ulimit -c unlimited’.
Verify again by using the ‘ulimit -a’ command.
➜ ~ ulimit -a
-t: cpu time (seconds) unlimited -f: file size (blocks) unlimited -d: data seg size (kbytes) unlimited -s: stack size (kbytes) 8192 -c: core file size (blocks) unlimited => new value -v: address space (kbytes) unlimited -l: locked-in-memory size (kbytes) unlimited -u: processes 709 -n: file descriptors 256 ➜ ~
