To have true portability you should use hex codes: `#DOS to UNIX perl -i.orig -pe 's/\015\012/\012/g' dosfile.txt` [download] Take a look at perlrun for the `-i` switch. And remember the following hash with newline for Windows, UNIX and Mac. I usually declare this on top of my program when i need to do lots of translation or outputting different kind of files `%N = ( WIN => "\015\012", UNIX => "\012", MAC => "\015" );` [download] `$\|=$_="1g2i1u1l2i4e2n0k",map{print"\7",chop;select$,,$,,$,,$_/7}m{..}g`	[reply] [d/l] [select]

To convert a DOS text file to a Unix text file using Perl, enter: `perl -p -e 's/\r$//' < dosfile.txt > unixfile.txt` [download] To convert from a Unix text file to a DOS text file with Perl, at the Unix shell prompt, enter: `perl -p -e 's/$/\r/' < unixfile.txt > dosfile.txt` [download]	[reply] [d/l] [select]

The SuperSearch yielded a relevant thread regarding this. To hurl in another few cents, Macintosh (I believe) uses a single "\r" or carriageReturn to terminate a line. There is also some quite strenuous discussion of the whole Unix Dos Mac Windows thing. Getting off topic now, since the question only regards doing this with shell oneliner. I searched the Q&A for a dummies guide to this, How to control UNIX vs DOS line feeds in Perl is pending approval by powers mightier than I	[reply]

This is somewhat dependant on what os you are working under. In a unix environment there are native tools to do this. On SCO Unix the commands are 'dtox' (dos to unix) and 'xtod' (unix to dos). On Solaris the commands are 'dos2unix' and 'unix2dos'. In linux (Red Hat I know of, maybe others) 'fixdos'. I am sure that other *nix os'es have similar tools. Don't know if this helps with what you may be attempting to do, just thought I would add my 2.7 cents.	[reply]

The dos2unix and unix2dos tools have been ported to nearly every unix around and are available (on FreeBSD in the ports) even on win32. "Nothing is sure but death and taxes" I say combine the two and its death to all taxes!	[reply]
