I am wondering if there is some function to turncate the last 40 chars of every line in a given file. And also, when I execute the system command like "system(". .profile");" in a C program, the profile is not executed.

awk '{l=length($0);if(l>40){print substr($0,1,l-40)}}' file

How do you proove that .profile was not executed?
I suggest adding following to your .profile:
echo "called at `date` by $user" > /tmp.profile

Then tell us what the error is, or what does not work.
