Yeah, I read the manpage - "cut" counts from 1 ;)
When using the "FROM">1 in "cut -b FROM-TO", the output is wrong:
$ openssl rand 16777216 > /tmp/zeroes
$ cut -b1-12000000 < /tmp/zeroes > /tmp/zeroes2
$ ls -la /tmp/zeroes*
-rw-r--r-- 1 user user 16777216 15. Jän 17:53 /tmp/zeroes
-rw-r--r-- 1 user user 16777217 15. Jän 17:53 /tmp/zeroes2
$ cut -b65-12000000 < /tmp/zeroes > /tmp/zeroes2
$ ls -la /tmp/zeroes*
-rw-r--r-- 1 user user 16777216 15. Jän 17:53 /tmp/zeroes
-rw-r--r-- 1 user user 13075377 15. Jän 17:53 /tmp/zeroes2
$ cut -b2-12000000 < /tmp/zeroes > /tmp/zeroes2
$ ls -la /tmp/zeroes*
-rw-r--r-- 1 user user 16777216 15. Jän 17:53 /tmp/zeroes
-rw-r--r-- 1 user user 16711969 15. Jän 17:53 /tmp/zeroes2
It doesn't happen with /dev/zero - so I guess some byte value isn't sent
through properly (NUL, or CRLF mismatch or something like that?).
Anyway, with byte positions I'd expect it to be clean and not do
any processing!
