What program to convert windows txt files to linux txt and vice versa?

Any command line programs to do so? Can vim or nano convert them for me? How do I go about it?

The package is called hd2u, the command is dos2unix. Despite its name it converts both ways. No man page, but --help works.

Vim can do so.  :set fileformat=dos and save, or :set fileformat=unix and save to go the other way.  Not for converting many files at once, but handy to know.

Naturally, Emacs does this as well.

And sed.

And sed.

Ya know - I _was_ going to say that as well, but then I tried a

 sed -e 's/\n/\r\n/

and that didn't work ... I guess '\r' and '\n' are not sed regex - I didn't follow it any further ...
'sed oneliners' would probably have given me the right syntax ...

Does this work?

sed 's/\x0D$//' #dos -> unix
sed 's/$/\r/'     #unix -> dos

Stupid question, how do you know if it works?

The only palatable way I can think of is :  od -x windows.txt

How it knew it is English, I have no idea.

Hmmm - the following is _not_right:

sed 's/$/\r/'

as it would give LFCR instead of CRLF

But `file` says it is:

ASCII text, with CRLF line terminators

Re: What program to convert windows txt files to linux txt and vice versa?

Yes, but the 'original' was a dos-file, then he used "tr -d '\r'" to make it into a linux file ...

Ahhh - I've just tried it out (sed 's/$/\r/') and for some strange reason, it _does_ give CRLF (never mind what 'file' says - the only way you can be 100% sure is doing a 'od -a').
OK, it does make some kind of sense (I guess). '$' is the end of the line - ie immediately prior to LF, so what it is actually doing is inserting a CR infront of the NL ... got it now!
And that's why my previous attempt didn't work - 'sed' kinda strips off the NL saying "this is where the line ends" and then when it writes out the record/line again, it adds the line terminator (NL) to the record.

Re: What program to convert windows txt files to linux txt and vice versa?

Yup, exactly. sed is not a binary stream editor (though you still can).

Edit: Curiosity got the better of me:

> file dos.txt
dos.txt: ASCII text, with CRLF line terminators
> od -a dos.txt 
0000000   d   o   s  sp   l   i   n   e  sp   1  cr  nl   d   o   s  sp
0000020   l   i   n   e  sp   2  cr  nl
0000030
> cat dos.txt | sed ':a;N;s/\r\n/\n\r/;ta' > flip.txt
> od -a flip.txt 
0000000   d   o   s  sp   l   i   n   e  sp   1  nl  cr   d   o   s  sp
0000020   l   i   n   e  sp   2  cr  nl
0000030
> file flip.txt 
flip.txt: ASCII text, with CRLF, CR, LF line terminators

Edit 2: Yes, I noticed that. I'm fixing it.

Edit 3: tr is still the man. Bad sed, no cookie:

> file dos.txt
dos.txt: ASCII text, with CRLF line terminators
> od -a dos.txt 
0000000   d   o   s  sp   l   i   n   e  sp   1  cr  nl   d   o   s  sp
0000020   l   i   n   e  sp   2  cr  nl
0000030
> cat dos.txt | tr '\r\n' '\n\r' > flip.txt
> od -a flip.txt 
0000000   d   o   s  sp   l   i   n   e  sp   1  nl  cr   d   o   s  sp
0000020   l   i   n   e  sp   2  nl  cr
0000030
> file flip.txt 
flip.txt: ASCII text, with CR, LF line terminators

The other edit kept for posterity.
