How to check the ulimit value in Linux?

In Linux systems, the ulimit command can be used to view and modify the values of system resource limits.

To view the current values of all resource limits for the current user, you can simply enter “ulimit -a” in the command line. This will display the current values of all resource limits, including soft and hard limits.

To view the current value of a specific resource limit, you can use the ulimit – command, where is the name of the resource you want to check. For example, to check the limit for the maximum number of open file descriptors, you can use ulimit -n.

You can use the command ‘ulimit -H’ to view the names and descriptions of all available resource limits for the hard limits, and ‘ulimit -S’ for the soft limits.

To change the value of resource limits, you will typically need to have root privileges or equivalent permissions.
