I am using shell script, getrlimit can be used in C i gues and it can't get the max open file limit for particular process.

As far as I know from reading the man page, the limit once set applies to all processes made thereafter. You can use the command to query both the hard and the soft limits, and, as far as I know, "what you get is the right answer."

For different process limits are different. We can fuind using /proc/<pid_of_process>/limits ,but i want another way to do this.
