Thanks guys for the reply

When I am debugging programs at work, I need to do the following very often:
1. cat the kernel log
2. save it to a file
3. open file and search for possible failures

So I wrote this small program to do the above 3 steps with one button click via TK
I put this program in a network drive in the lab where IT set it up that can be accessed by everybody on their own machines.

I can't really show the error message here because I can't reproduce it on my machines or any of the machines in my lab.
As I remembered that I couldn't open the text file on others' machine and windows popped out warning message.
