Append: file contains ^M characters for binmode mount

Append: file contains ^M characters for binmode mount

[lau bella]

Hi all,

Append to previous message, i found somethings:
1/ When i run bash script in cygwin, e.g.
   #!/bin/bash
   echo "123" >> output_file
   echo "456" >> output_file
   echo "789" >> output_file
   
   the output file is in unix mode, i.e. without ^M at
the end of each line. 

2/ When i run perl (cygwin perl), exp (export of
oracle) and ftp in cygwin, the output files are in DOS
format. When i vi the output files, the ^M is not
appear in vi, but at the bottom of screen, it shows 

"fileabc" [dos format] 3 lines, 209 characters

Is the output_file generated by other software (e.g.
oracle, perl) should generated as DOS mode, even run
in cygwin ? But perl is bundled by cygwin.

Thanks again. 




Hi all,

I installed Cygwin 1.3.10 in another w2k machine (
this time i installed in w2k professional). I used
"unix format" to install. All mount point are in
binmode:

c:\cygwin\bin on /usr/bin type system (binmode)
c:\cygwin\lib on /usr/bin type system (binmode)
c: on /cygdrive/c type system (binmode)

As I want to simpify the problem to see whether it
related to "binmode" or not, i installed cygwin in c:\
cygwin and use c:\cygwin\home as home directory.

I run the perl (/usr/bin/perl) script again, 
1. I use "vi output_file", i cannot see ^M at the end
of each line. But at the bottom of screen, i see 

"fileabc" [dos format] 3 lines, 209 characters

2. When i use "cat -v output_file", ^M are contain at
the end of each lines.

3. When i use "od -c output_file", "\r\n" conatin at
the end of each lines.

4. When i run "dos2unix output_file", the file size
decrese.

I would like the output file should be in UNIX format.
Would you mind give me some
suggestion. Thanks for your kindly help.

Yep.  Historically, this has been an issue for Perl (from Cygwin).  I believe
the issue persists.  Check the email archives if you want more information.
