 Is there a way to make this work in Cygwin.

Not with sed, which is treating all input as text.  But it should work
with gawk.  I just tried it by myself, using the latest gawk-3.1.3:

$ awk '{ if ( NR  8 ) print $0; }'  a|od -tx1
000 31 32 33 0d 0a 39 39 39 0d 0a 34 35 36 0d 0a

awk / sed - trouble with CR character

The binary line contains the 0x0d.

E.g.

$ od -tx1 a
000 31 0a 32 0a 33 0a 34 0a 35 0a 36 0a 37 0a 38 0a
020 31 32 33 0d 0a 39 39 39 0a 34 35 36 0a

This works fine under Sco unix.

I have installed Cygwin in 'Unix' mode, so I'm not sure what is going on.

Thanks for any help.
