If file modified execute a script
I have some server application running on FC6 but clients loose contact unless they restart client application after server ip has changed. And it changes once a day I think. I have inadyn running since clients connect to dyndns address but they still can't reconnect unless they restart client tool or I restart server application.
So I was hoping there is a way to run something that would restart server when it notices that inadyn.log file was modified. Since file is modified when it updates to new ip.

Hmm
You need to store your inadyn.log log file current time somewhere. Then you can monitor current time and compare with stored location. If both differ restart the server. Logic/script: Code:
#!/bin/sh file="/path/to/inadyn.log" fileatime="/etc/current.time" a="" b="" [ ! -f $fileatime ] && stat $file | grep Modify > $fileatime || : [ -f $fileatime ] && a="$(cat $fileatime)" || exit 1 b="$(stat $file | grep Modify)" if [ "$a" != "$b" ]; then echo "Restart server...." # update time stat $file | grep Modify > $fileatime fi
