Please explain this shell log:
$ echo a | sed 's/a/\^M/' | od -t x1
0000000 0a 0a
0000002
The "^M" was a real control-M input via emacs-like ^Q^M.
Why isn't that first "0a" a "0d" as expected.
I can't believe "sed" has a bug.

Try using \r instead of ^M...?

Works fine for me, both with and without the backslash. Perhaps your
shell is doing something funny with the ^M. Try replacing "sed" with
"/bin/echo" and see if the argument is getting through intact.

I've noticed in my RedHat 7.2 install that 'tar' doesn't seem to work. For
any file xxxx.tar.gz when I issue the command
tar --gunzip --extract xxxx.tar.gz
(or with 'z' replacing '-gunzip', 'x' replacing '-extract'), absolutely
nothing happens. When I finally stop it with a Ctrl-Z, the prompt comes
back, and then I can kill the stopped tar process. This behavior is in-
dependent of my being root or user, and occurs both from a cmd line shell
and from MC's cmd line.
Further, if I first unzip the *.gz file using gunzip, then use 'tar':
tar --extract xxxx.tar
exactly the same thing happens.
OTOH, from MC I can simply press Enter on the *.gz file and see all its
content, and also copy any selection of files to whereever I want. So ap-
parently 'tar' or its equivalent works for MC, but not for me the way I was
trying to use it. Anyone have any suggestions as to what I'm doing wrong?
Thx.
