Hello my fellow scripters.

Im currently working on a script hat needs to check a specific file for changes.

The idee is to let the script sleep until the specific file gets updates or changed and then resume the script. What is the mot effective way of doing this?

Check the filezise is not practical since the size be the same evev if the file has been chaged. I dont want to read the entire file once every second.

Any smart idees?

@scullion: A file can be saved without changes and therefor have a modified time stamp.

@Tjalve: Look at _Crypt_HashFile using MD5 or SHA1.

Edit: Actually a combination of both would be best. Watch time stamp for changes then check hash to make sure.

Whenever someone says "pls" because it's shorter than "please", I say "no" because it's shorter than "yes".

Tjalve,

seangriffin's FileSystemMonitor UDF will allow you to see when the file has been altered. I have used it very successfully to detect such changes. :)
