Howto check under Linux why a file or resource is busy, I mean which program is using this file?

I don't know. Here in HP-UX land, we sometimes use a utility called lsof. I suspect there is probably a port for you in linux land, too.

Shalom,

lsof started out on Linux. So lsof is a good way to find out what is occupying the resource.

fuser works to, but the HP-UX switch -c does not work on Linux, you'll need to consult the man page to work that out.

Chris,

Specific to your question,
lsof filename

And to see all files in use by a particular process:
lsof -p -processid

For the rest, man lsof

Hi Chris,

lsof (no options) will list all files opened by any processes currently running. To restrict this to processes owned by username,

# lsof -u username

# lsof +D /directory will show processes which have files in this directory open.

# lsof -c processname will show all processes beginning with processname that have files open;
# lsof +p PID does the same thing for a process ID.
# lsof -i will get you information about IP sockets.

Check out the man page for more detail and for the many other available options.
