List or count open files

[Ed Hon]

How do I list or at least count the files a process has open?

Hi,

You can see them with Glance, or you can use a tool like 'lsof', which you can find here:

or here:

to confirm, LSOF (LiSt Open Files) is a great tool to have. Keep in mind, that a process-id might have many threads open to a file. LSOF shows all the files open per process, but also a file can be shared-open.

so to make a point. if you compare the open files on the system network:

netstat -an

and compared to

lsof

then lsof may show you more open files.
