5 "cat" outputs duplicate CR - ID: 2728605

Last Update: Settings changed ( earnie )

Details:

MSYS 1.0.11(0.46/3/2) 2009-01-29 00:39 i686 unknown; targ=MINGW32
cat (GNU coreutils) 5.97
Windows Server 2003 64-bit

When the text files a.txt and b.txt are concatenated (see attachment),
MSYS' cat.exe outputs a duplicate CR after about 1000 bytes. Both a.txt
and b.txt have CRLF line endings. Line lengths in these files seem to
matter, you can't trigger the bug with any kind of text files.

See bug.cmd in the attachment for how I invoked cat.exe to trigger the bug.
The bug does NOT occur when cat.exe is invoked from MSYS' bash.exe.

Date: 2009-04-03 19:41 Sender: earnie If you're using some other shell to redirect the output then it isn't a problem with cat.exe since it is the shell that opened the pipes. You will need to complain to Microsoft about its buggy cmd.exe or maybe there are options where you can cause the pipes in the shell to be open in binary mode instead of text mode. This issue has been closed. If you have further questions then please ask at mingw-users@lists.sourceforge.net.
