What is a "busy file? How can i delete in TCL script?

• Email
• Follow

Hi,

I have a tcl script that generate a lot of intermediate files (and
folders). At the last step of my script, I've to clean the working
directory and keep only one or two files.

I have written a proc to clean work dir like this:

proc cleanWorkDir {dir keep1 {keep2 ""}} {
set here [pwd]
cd $dir if {$keep2 == "" } {
set keep2 $keep1 } foreach f [glob -nocomplain *] { if { ![string equal$f [getOnlyName $keep1] ] && ![string equal$f [getOnlyName $keep2]] } { file delete -force$f
}
}
cd $here } Although it worked on my laptop, but on customer's Linux machine I always get error message: ERROR: cannot remove A/B/.nfs00000000010d28ba00004dfb': Device or resource busy while executing "file delete -force$f"
....

Despite of being able to delete the whole folder (Folder "A" in error
message) manually, I don't understand why cannot the TCL script do it!

Can anyone help me solve this?

Thanks,

I have also noticed something.. When the TCL script exits after this
error, and I try to "ls" the ".nsf...." file it complains about, I
don't find it!

What is the .nsf file stands for? Who generates it?

Thanks,

NFS -- 'Network File System', a UNIX file sharing protocol, originally
invented by Sun Microsystems back in the late 1970's or so. The
".nsf...." file is something created by the NFS software, I think
related to locking.

This is a very nice to know, thank you.

Your script is trying to delete all files in a directory except those
you specify. It would probably be better to maintain a list of the
temporary files and just loop through the list at the end deleting them,
that way you avoid trying to delete other files (like the NFS lock files).

I agree with Robert that the lock files can't be deleted. The first
question you should have is why are they being created. Is there some
good reason that the files you have created are being locked by a
remote host? If not then I would spend some time figuring what the
heck is going on. Second, the /tmp directory on unix/linux is where
you should be putting all your temporary files. This directory is
cleared when a system is rebooted which will remove any abandoned lock
files. In a large network it is possible for lock files to become
abandoned which is a real headacke because they will prevent
directories from being deleted.

To see the file you should propbaly try
ls -al
This lists all files including hidden ones, under Linux the . before a
filename will hide them from simple ls

You should probably be creating a private tmp directory in /tmp to
keep all your files together then a simple delete of the directory
should clean up easily.

Those .nfs files are not related to file locking, but to removed files
on an NFS share which are still open in some application.

@Ahmad

may be one more tip is you can use exception handling if script is
actually aborting without completion where you can use tcl catch
statement for file delete operation and print messages when some cases
it fails as busy etc.

How can I delete the LDB file...? It didn't delete itself because a remote user didn't do a proper shutdown.
If this is a dumb question, bear in mind I am new to MDB. A customer has approx 6 computers (win9x) connected together. One win98 computer has some shared folders on it's C drive which everyone can access. They call it the server and no one sits at that station. I installed an application on 4 computers and I placed its MDB file on the "server". Whenever I go there, I notice that I can't delete the LDB file, even when everyone shuts down their application and computer. The LDB file appears to contain names of various users. I suspect that they are just turning off their...

Script to Delete All But Latest File
I have some db2 database backups in a directory. They take up a lot of space, so I'd like to delete all but the latest. I can't use "find" and "rm" because the backups aren't done on a predicatable interval. The only thing I do know is that I only want the latest one, and delete the rest. If there is only one in the directory, of course I don't want to delete it. Can any bash experts give me some ideas? Buck Turgidson wrote: > I have some db2 database backups in a directory.
