How to find out how many file descriptors I am using?
 

Greetings. I learned how to use file descriptors but never seen a way to check how many I am using. Any help is great.

You'll find some interesting 'stuff' from a web-search of: ls /proc/self/fd
(ulimit may also be semi-relevant) wiki here.
Great to see learning; best wishes & welcome to LQ!

I got the hint from one of the answers in the link. To see the current file descriptors that I imitated is:

ls -l /proc/PID/fd

To get the current PID of my session on the terminal is simply

echo $$
