reading a file line by line in unix

#!/bin/ksh

while read line
do
echo $line
done < mydatafile

thanks nail. this kind of solved my problem too. Now, i have a question about this. I have this files that print garbage charactors. Its very hard to define those charactors and hard to find it too. and these charactors are different for different editors ( what i mean is if i open in nedit it will be like <soh> , if i open in text edit its like ^@).

what your script does it read line by line so its gonne stop at this perticular line and just gonne think and not do anything. is there anyway to get out and print an error message?

Thanks for all your help.

Note: this charactors doesnt work with grep or there is no way to find it.
