Hello, I have this small C app that someone wrote for me ages ago, and
am tired of it breaking every time I move it around to various
systems, I will include it below.
I am hoping I can do this in perl, as a one liner, were it will read a
the first 4 bytes of a file, grab 4 bytes out of the file, which is a
big endian value, and return that as an int to me.
perldoc -f read
perldoc -f unpack
perldoc -f pack
And to simplify the code (so that you do not need to explicitely open
the file), look also into
perldoc perlvar
at the ARGV filehandle.
HTH, Jenda
