Log message check

[Jeeva Sarma]

Hi
I want to write a script which will check if the log
message is more than 80 characters and if so,to break
it into the next line.(more than 80 characters
sometimes gives compile errors in linux).
I could get the log message into a variable using 
head <$1.
After the check,when I give fold command like 
fold -80 `head <$1`,it doesn't break the log message
at 80 characters.Any ideas how I may achieve this?

Thanks,
Jeeva Sarma
