Error checking a file from previous file size

Hi,

I'm currently trying to write a script that checks a log file for certain errors. Once checked it then records the filesize in another file. All this is fine, my problem is that the next time I do my error check I only want to check from previously recorded filesize to the end of file. I'm not sure how how to script this so that it starts reading the file a certain specified file size so any suggestions or examples would be greatly appreciated.

tail -c <size> is your friend :wink:

Thats the one, thanks for your help.
