event or file wait scenario
i want to do 2 things
1) i should wait for a file called A.txt to fall on a specific path on the server 2) once the file arrives immediately another script called B.sh should be executed. Could you please throw somelight on this. Any code if already present that would be helpful. Regards Rajesh |

One way is to sit in a sleep loop.
Code:
while true
do
if [ -f A.txt ]
then
sleep 10
else
break
fi
done
b.sh
avronius is right. Unless the file is a simple flag created with something like "touch" it could be not ready for processing. |

This link might help you a bit:
scripting running every minute Have the script check for the existence of the file that you are referring to - if it finds the file, do stuff... - Avron |
