Command to know which process is using a certain file

Hi all,

What is the command to know which process is using a certain file ?

Thanks,
Frederic

Code:

---

lsof

---

is what you want.

to see what's using a file (lets say "filename") use:

Code:

---

lsof | grep filename

---

should sufffice

i thought it was :

Code:

---

fuser [files | filesystems]

---
