As [almut] says, this is nothing to worry about. If you carefully look at your <c>strace</c> output, you'll see that perl even performs a <c>TCGETS</c> ioctl on the your script file!
<p>Perl makes other information gathering calls when it opens a file such as calling <c>_llseek</c> with whence set to <c>SEEK_CUR</c>. You might wonder why perl has to ask what the file position is if it just opened a file. It turns out that it's logically cleaner to always ask rather than assume.
