track down log for 1 file

[tarsiran]

how to find what processes have written to a file on Linux?
Is there a way to find out which process wrote to a give file earlier. I am having a problem where multiple processes seem to be writing to a file. I know one of the processes but not sure who else is writing to the file. I am on linux/cent os. Is there a way a log is mantained by the OS on what processes have written to a specified file

please help me

@tarsiran,

Hello,

in realtime you might want to use lsof.

If you've got no lsof installed on your box, then you can install it from packages both on CentOS and Ubuntu/Debian.

 

[tarsiran]

can you explain more dude?

Once you've got lsof installed on your system run

man lsof

for documentation.

@tarsiran,

You'd better find some reading for beginners:

These forums is not the right place to ask questions on how to use man and other linux commands.

As an example of using lsof:

lsof | grep log$

In order to learn what does it show, please read official documentation.
