According to Norton Allen on 1/28/2007 1:08 PM:
I'm wondering if the problem I am seeing is from the same source. I find
that 'apachectl stop' no longer works since a recent cygwin update. I
can see that the PIDFILE is being written with a \r\n line ending.
'apachectl stop' then reads the file with
PID=`cat $PIDFILE`
cat is not a bash builtin, so no this is not the same problem. Are you
running a script with CRLF line endings on a binary mount? If so, read
the announcment, and use d2u on your script.

No, this is a text mount:
Cygwin> mount
[cut]
d:\Data on /Data type user (textmode)
[cut]
Cygwin> cd /Data
Cygwin> echo hello >test.txt
Cygwin> xxd test.txt
0000000: 6865 6c6c 6f0d 0a hello..
Cygwin> foo=`cat test.txt`
Cygwin> echo "'$foo'"
'hello
Cygwin>
Note the trailing quote is missing because of in intervening CR. It
seems that the discussion of confusion about whether a program should be
in text mode or binary mode when pipes are involved would still be
relevant here.
