When I create a file using notepad:
This is a text file created with Notepad.
It has DOS (CRLF) line endings.
Look at it using "wc":
dpchrist@p42800e:~$ wc textfile.txt
2 14 76 textfile.txt
And then look at it with Cygwin "od", I see:
There is nothing wrong here. You installed cygwin with text mode
mounts:
C:\cygwin / system textmode
C:\cygwin/bin /usr/bin system textmode
C:\cygwin/lib /usr/lib system textmode
.. /cygdrive system textmode,cygdrive
This means that when a cygwin program reads a file with CRLF endings it
is translated to LF line endings that all unix tools expect. You want
binary mounts if this is not what you desire. See the FAQ for more
info...
Hmm, I don't get it.
If I create a file with notepad, containing three readable bytes and a
linebreak and save this on a textmode mounted directory then I see this:
$ wc 123.txt
1 1 5 123.txt
$ od -c 123.txt
0000000 1 2 3 \r \n
0000005
$ pwd
/perl
$ mount | grep /perl
H:\perl on /perl type system (textmode)
And I see the same result when moving the file to a binary mode mount:
$ wc 123.txt
1 1 5 123.txt
$ od -c 123.txt
0000000 1 2 3 \r \n
0000005
$ pwd
/tmp
$ mount | grep /tmp
H:\tmp on /tmp type system (binmode)
