Obviously your sed doesn't like the leading characters of the input lines, which are "^".
Just try
If I were you I'd create a fresh file and create a couple test lines like following:
and run sed again and see what happens.

Hi.
I ended up with a long script that compared the results of cut, 3 variations of sed, and the binary editor bbe. I did these on Linux and Solaris 10 (but bbe omitted on Solaris). I used cmp as the first test, and then diff for the detailed comparison. On Linux, GNU diff bails out quickly, simply saying that the binary files differ.
The sed variations that I used were:
They failed on both Linux and Solaris:
I used the cut output as the standard. The bbe output compared successfully.
Observations:
1) mixed-mode files are not best-practice
2) cut knows about bytes, and appears to use its byte "knowledge" as its character knowledge
3) sed is advertised as:
not necessarily collections of arbitrary bytes in mixed-mode files
4) At the center where I worked, we said that we could make processes (almost) as fast as you desired as long as you didn't care about the results. If you get good results in a reasonable time from a particular process, then use it. You may end up wasting more time trying to find the fastest method than if you just let the original process run. This is a kind of case of premature optimization, along with the notion that people time is the most expensive (in most cases).
5) I did not time bbe, but it might be as fast as sed -- it is:
I can post the script and results, however, as I said, they are lengthy. As usual, it is possible that I have incorporated an error of some kind, but in general I agree with the OP ... cheers, drl
A quick peek at sample.conf shows that the first byte in the lines is a null byte. It's a safe bet that what you are seeing is a sideeffect of c string functions interpreting a null byte as end of string.
For experimentation's sake, does the discrepancy persist if you substitute a 001 byte for the 000 bytes?
If it does not, mystery solved. If it does, weird. Could that sed implementation be filtering out control characters?
Hi I'm having a problem with a sed command that I thought I was using correctly but apparently that's not the case.
I was hoping someone here could point out what it is I am doing wrong?

Why all partitions behave differently? As clear from the attachments, for some partition, delete option is disabled. See 'Disk 1' which is my memory card.

Hi, all.
Here's the problem:
sed '/FOO/,/BAR/p'
That should print anything between FOO and BAR, right?

Hi,
We have few hundered scripts using cut command in thousands of lines. On HP-UX shell script developer used echo "ABCEFG" | cut -c -1-3 to cut first three character of the string.
