how to check number of opened handles

ruj.sabya · 08-06-2007, 04:52 AM

In windows systems, I can check number of opened handles by a process, by simply enabling "hanles" column in taskmanager.

Is there anything similar(command or GUI) in linux, by which I can check number of opened handles by a process?

Actually I have created an application, and I want to check if any resource is leaking!

Code:

ls /proc/whateverprocessnumberyouwant/fd | wc -l
#                                              ^
#                                              ^
#                                             ell, not one

If it turns out you have a leak, you can even find out what the names of the open files are:

Code:

ls -l /proc/whateverprocessnumberyouwant/fd

Hope this helps.
