I am a new user. can somebody tell me what does the command 'ulimit ' do ?

man ulimit

limit, ulimit, unlimit - set or get limitations on the sys-
tem resources available to the current shell and its descen-
dents


In your current shell this states how many files you can open, max file sizes, etc, etc

See a piece of the manpage below:

-c maximum core file size (in 512-byte blocks)

-d maximum size of data segment or heap (in kbytes)

-f maximum file size (in 512-byte blocks)

-n maximum file descriptor plus 1

-s maximum size of stack segment (in kbytes)

-t maximum CPU time (in seconds)

-v maximum size of virtual memory (in kbytes)

Normally you will not need it, but stuff like Oracle ( because it might need more files open, more memory,etc,etc) can demand it.

Have'nt u tried man ulimit................
try it.
the man pages are quite helpful

Ulimit
Provides control over the resources available to the shell and to processes started by it, on systems that allow such control.

So it gives u answer unlimited

Good luck...
And have fun exploring Linux
