Adding a while loop to my script
I have a script below that goes to the given directory and plays the newest powerpoint presentation via powerpoint viewer and wine.
So far it works perfectly but now Id like to add a while statement to essentially run
Code:
find /ticker/powerpointshare -mmin -1 -type f -iname "*.ppt"

and if it finds a file then execute the top half of my script again.


Code:
#! /bin/sh

# Start the newest Powerpoint presentation

# Change Directory to /ticker/powerpointshare
cd /ticker/powerpointshare

# Creates the variable newppt for use in this script
# ls -tr sorts the the ls output and pipes in into tail to grab the newest file 
newppt=$(ls -tr | tail -1)

echo This is the newest powerpoint presentation
echo $newppt
cd /ticker/powerpointshare

# We use wine to open the powerpoint presentation  with Powerpoint Viewer 2007
wine "C:\Program Files\Microsoft Office\Office12\PPTVIEW.EXE" /N $newppt

exit

How would it know when to stop? Wouldn't it just run powerpoint over and over?

I was thinking of killing the process if it finds something and regarding the powerpoint its meant to play in a loop until it finds a new powerpoint presentation

Some basic
If you want infinity times, each ten seconds. I suposse your ppt has a limited duration and prompt automaticaly when finish.

Code:
#!/bin/ksh
while true
do
./your_script.sh o your code
sleep 10
done

Any idea why this script wont execute via cron on my ubuntu box?

The same reason lots of things don't run in crontab according to our FAQ, a much more minimal environment than you get from a login. Try setting PATH to a more complete value yourself, or sourcing /etc/profile

By full path do you mean that I should try to give it the full path to execute wine from the script above?
