What does Dos mode vs unix mode mean when you install cygwin

What does Dos mode vs unix mode mean when you install cygwin

[Castle, Eric]

When using the installer to install Cygwin 1.3.2, there is a step where it
asks what the default text file type should be, with the 2 choices being
either dos or unix.  What is the difference between the 2 choices?   Is this
just how cygwin, including processing files in perl, uses either \r\n or \n
for line termination?

I don't recall the old installer program (called full.exe) ask that question
back on B18.

Any recomendation on which type to use? I've been choosing "dos" but not
sure what that is really doing vs choosing unix. 

Thanks,
Eric

That's correct, a "dos" file has \r\n terminators

So back then I got in the habit of never using "dos" files in cygwin.

Entirely a matter of preference, and what the non-cygwin apps you intend
to use prefer.  For me, the hardest part of "unix" files is remembering
to always ftp "binary" and not to attach files to Windows e-mail unless
they are suffixed .doc or converted.  More and more apps can deal with
either kind of file.

UNIX = binary = faster read/write (no CR/LF conversion needed)

The Cygwin ftp from the inetd package should use binary
as default when connecting to a UNIX system.

Hi all,
Man is having problems formatting pages and crashes out - any ideas?

Yes, and how text files are created, by default.

It's a fairly new feature.

I've had perl scripts copied over from the Linux box break because I was
using chop() to get rid of line endings instead of chomp().  If you tell
Cygwin to expect Unix line endings, that problem doesn't occur, but
then, maybe you have a lot of DOS text files already.  If I try to use
Cygwin on my Visual C++ source files, for example, I need to be using
DOS text mode.

That's why you're given a choice -- one answer isn't right for everyone.

Hmmm, an *ix lover at Intuit...so when's Quicken for Linux coming out?
