sed end of line

sed end of line

[Timo Maier]

Hello, I have a problem with sed.

Ubuntu:
timo@serv6:~# echo "CHANGE MASTER;" | sed '/^CHANGE MASTER.*/ s/.$/ for channel "de";/'
CHANGE MASTER for channel "de";

Works as expected.

Windows:
C:\> echo CHANGE MASTER;| sed.exe '/^CHANGE MASTER.*/ s/.$/ for channel "de";/'
CHANGE MASTER; for channel "de";

last character ";" is not being deleted

now with a second "." before "$" (to delete last 2 characters):
C:\> echo CHANGE MASTER;| sed.exe '/^CHANGE MASTER.*/ s/..$/ for channel "de";/'
CHANGE MASTER for channel "de";

This is how I want it.

Why do I need a second "." in the cygwin sed?

sed.exe --version
/usr/bin/sed (GNU sed) 4.4
Packaged by Cygwin (4.4-1)

Hi Timo.

The difference is in echo.

$ /bin/echo "Hey" | /usr/bin/hexdump -C
00000000  48 65 79 0a                                       |Hey.|
00000004

C:\>echo Hey| c:\cygwin\bin\hexdump -C
00000000  48 65 79 0d 0a                                    |Hey..|
00000005

Dear Timo,

you are mixing a DOS echo which will produce a \r\n line ending with a Cygwin sed which expects \n line endings. The second . matches the \r.

Either work in bash and use Cygwin echo or use a MinGW compile of sed or strip the \r e.g. with tr or maybe match it more explicitly with a \r.

I already thought it's something about EOL, just wanted to make sure if this is not a bug. Thanks.

Or use Cygwin printf "%s\n" "Hey" to avoid differing echo output.

Or when in cygwin, make sure your cygwin paths are first.
