[bug-gawk] The best way to test the first n character in a file

[Peng Yu]

Hi,

I want to test if the first n character of a binary file equals some
given string. I am not sure if awk is good at this. It seems that
`head` plus shell code should be easier. Is there a good way to do so
in awk? Thanks.
