Dtrace: openfile.d script

Posted in Dtrace at 3:14 pm by alessiodini

Today in my free time i wrote this script.

It can be used in a follow scenario:

“We have the important file /tmp/pippo ( simple example ) that sometimes it is corrupted by some command/process. After a restore we see now that file is corrupted for second time. Who open it?”
( i suggest you to zoom the screenshot for full vision )

In this situation i use openfile.d as follow:

# cat /tmp/pippo
boss
boss

# ./openfile.d
Usage:

./openfile.d [ -f file ] [-l] -h

-f = file to check
-l = see info about numeric codes

In another window i have launched a couple of commands on file /tmp/pippo !

This script can be downloaded here.
If u have some suggestion or u want help me to make it better… u are welcome 😉
