Tool which shows me which files are written in Linux?

I found in IOStat, that some part of my application is writing extensively, but I don't know which process it is and what files it is writing to. In Vista there is a tool fo that which shows the files that have been active in the last 30 Seconds. Is there something similar for Linux?

If you want to see all the file accesses in real time (up to 32 processes) you can use this command:

strace -f -e trace=file `ps aux | tail -n +2 | awk '{ORS=" "; print $2}' | sed -e 's/\([0-9]*\)/\-p \1 /g' | sed -e 's/\-p  $//g'`

What you are looking for is lsof. It's a command line tool but there is also a GUI for it at sourceforge.

lsof will list all open files for a given process:

lsof -p

Linux provides a file change notification API called "dnotify", along with a command line utility dnotify. You can use that to keep track of the changes over the last 30s.

I would probably write an application that builds directly on the Linux API, and discards all events older than 30s.

Not sure of a program but the find command in utility has a lot of options which will allow you to find files and/or directories that have been modified within a certain time period.

For example:

$ find /home/you -iname "*.txt" -mtime -1 -print

Would find text files that were last modified 1 days ago.

You could wrap this call in some sort of script or write your own quick little app to use the results.

To find all files modified in the last 24 hours (last full day) in a particular specific directory and its sub-directories:
