ulimit -u command

[praka123]

My Debian shows the o/p of "ulimit -u" as "unlimited".
btw ulimit is the parameter which determines how many processes can a user account can run.U can customize the max no of processes via ulimit.

root@ubuntu:~# whereis ulimit
ulimit: /usr/include/ulimit.h

Thanks for the info. Mine too shows unlimited. But, actually, I think there is a limit. In my OS class, I was taught that the PID size is determined by the datatype pid_t which is 16 bit. This means that a total of 65536 (2^16) PIDs are possible. After seeing your post, I did some search on this and got this from Wikipedia.

Version 2.6 - current (December 17, 2003 to the present)
Increased the maximum number of process ids from 32,768 (= 2^15) to over 1 billion (2^30).

So, may be, now the PID size is 32 bit. I don't know if there is any other variable determining the total number of simulataneous processes in the system.
