How to check no. of files open currently
I'm getting an error "too many files open"

# ulimit -a
time(seconds) unlimited
file(blocks) unlimited
data(kbytes) unlimited
stack(kbytes) 8192
coredump(blocks) unlimited
nofiles(descriptors) 256
memory(kbytes) unlimited
#

hard limit shows 1024

I would like to know how many files are open currently before I increase it.

Thanks in advance.

The ulimit (-n) is the number of files that can be opened by any single process, not by the system as a whole, so it's for a specific process you need to know this information.

There are several ways to find this information, the easiest being to install lsof and use that. You can however see which filedescriptors are opened by a proceess by looking in the /proc filesystem.
