I can not delete a file (System says "busy")

cbozlagan — Mon, 16 Apr 2007 03:00:53 GMT

System gives me that file was busy.From this reason I can not delete that file.

How can I learn which process is holding that file.

Is it enought to kill that process to unlock the file?

thanks?

Hi,
if you know which process and you are ceratin you do not need that data, yes.

I would recommend lsof:

http://hpux.connect.org.uk/hppd/hpux/Sysadmin/lsof-4.77/

to identify the process for certain.

Use fuser command to see what is process. Another options is lsof http://hpux.cs.utah.edu/hppd/hpux/Sysadmin/lsof-4.77/

fuser /filename

then check man on fuser because it offers certain switches to kill the process however you can run various ps commands on the output from fuser:

fuser /
23450c

ps -ef |grep 23450

etc

check out the man pages.

You can use fuser or lsof.
Yes, once you kill the process the file shouldn't be busy.

Note if the file is an executable or shared lib, ps(1) will show who is running that program.

If the file is being executed, you can "move" it aside, without killing the process(es):
(Assuming you want to replace the file:
$ cp /path-to-new-file/file file.new
$ ln file file.old
$ ln -f file.new file
$ rm -f file.new

I think the only time you get this message is when the file in question is an executable that is running (or possibly a library file), in which case it should be easy to spot the name in the 'ps -ef' listing.

For ordinary files that are in use, you can 'rm' them, and when the last process using the file dies, the space is freed; you don't get a message about the file being busy.

What's the filename, the actual command you are running, and the exact error message?

HI

Check process id using
ps -ef|grep file name

then use kill command like
kill -9 id

and Remove file by using rm command
