Dos2Unix / Unix2Dos - Text file format converters
Convert text files with DOS or Mac line breaks to Unix line breaks and vice versa.
WCD - Wherever Change Directory|
This is an update of Benjamin Lin's implementations of dos2unix and
unix2dos. Benjamin Lin's implementations of dos2unix and unix2dos were
distributed via SunSITE.unc.edu (later MetaLab.unc.edu, now ibiblio)
and became part of several Linux distributions such as RedHat, Suse,
Gentoo, and others. This update includes all RedHat patches and fixes
several other problems. Internationalization has been added and ports
to DOS, Windows, Cygwin and OS/2 Warp have been made.
These implementations of dos2unix and unix2dos have been modelled after
dos2unix/unix2dos under SunOS/Solaris. The first versions were made by
John Birchfield in 1989, and in 1995 rewritten from scratch by Benjamin
Lin. Mac to Unix conversion was added by Bernd Johannes Wuebben in
1998, Unix to Mac conversion by Erwin Waterlander in 2010.
In 2010 the two separate dos2unix and unix2dos packages have been
bundled into a single dos2unix package (version 5.0). Support for
Unicode UTF-16 was added in 2012 (version 6.0).
- Native language support: Brazilian Portuguese, Chinese (traditional), Danish, Dutch, English, Esperanto, French, German, Hungarian, Norwegian Bokmaal, Polish, Russian, Serbian, Spanish, Ukrainian, Vietnamese.
- Automatically skips binary and non-regular files
- In-place, paired, or stdio mode conversion.
- Keep original file dates option.
- 7-bit and iso conversion modes like SunOS dos2unix.
- Conversion of Unicode UTF-16 and UTF-8 files.
- Conversion of UTF-16 files to UTF-8
- Handles Unicode Byte Order Mark (BOM)
Latest version: 7.1-beta2 (2014-09-16)
Stable version: 7.0 (2014-09-09)
2014-09-16: Version 7.1-beta2. Options -i, --info can have extra flags to change the output. For instance to print only the number of Unix line breaks, or print only the files that have DOS line breaks.
2014-09-11: Version 7.1-beta1. New option -i, --info, display file information. This new option prints number of line breaks (DOS Unix Mac), the byte order mark, and if the file is text or binary.
2014-09-09: Version 7.0. New option -u: Keep UTF-16 encoding of input file. New option -v: Verbose. Print extra information about amount of converted line breaks and BOMs. New self-tests. Stdio mode does not automatically set quiet option and does not automatically force conversion of binaries. Code cleanup.
2014-08-03: Version 6.0.6. Bug fix: mac2unix conversion produced corrupted output from UTF-16 input file. New options -b (keep BOM) and -r (remove BOM). New translation of the UI messages: Norwegian Bokmaal.
2014-04-17: Version 6.0.5. New translations of the UI messages: Brazilian Portuguese, Chinese (traditional), Danish, French, Hungarian, Polish, Serbian, Ukrainian, Vietnamese. New translations of the manual: Brazilian Portuguese, French, German, Polish, Ukrainian. Windows version skips by default symbolic links.
2013-12-30: Version 6.0.4. Build Windows 32 bit version with Large File Support (LFS), this fixes problems with (huge) files on network shares. New Russian translation of messages. New options -ul and -ub to convert UTF-16 files without BOM. Print value of binary symbol when found.
2013-01-25: Version 6.0.3. Dos2unix compiles with Microsoft Visual C++. Print system error when writing to output fails.
2012-12-11: Dos2unix moved to a new subversion repo. See below.
2012-09-06: Version 6.0.2. The locale encoding detection has been fixed when NLS was disabled.

2012-07-25: Version 6.0.1. The Spanish translations and the manual have been updated.
2012-05-06: Version 6.0. Conversion of Windows UTF-16 files to Unix UTF-8 files. Conversion of Unix UTF-8 files to Windows UTF-8 files with byte order mark.
2012-03-10: Version 5.3.3. Enabled wildcard expansion for all versions. Fixed a compile error when compiled with debug enabled.
2012-01-27: Version 5.3.2. Native MSYS version. Wildcard support on OS/2. Compiles with OpenWatcom for dos32 and win32.
2011-08-09: Version 5.3.1. Spanish translation of messages and manual. File ownership is maintained in old file mode (Unix only). Source code cleanup.
2011-04-26: Version 5.3. Improved handling of symbolic links. Improved error handling. Improvements for Cygwin.
2011-03-04: Version 5.2.1. Improved error messages. Enable Large File Support. PDF manual generation is optional.
2011-01-31: Version 5.2. ISO mode supports same code pages as SunOS dos2unix (CP437/850/860/863/865) and CP1252. Removed generated documentation files from source package.
7bit and Iso mode can be used in Mac mode.
Form Feed is treated as legal text character.
2010-08-18: Version 5.1.1. Dutch manual. Fixes compilation on Darwin OS. Win64 port.
2010-04-03: Version 5.1: Esperanto translation. Merged man pages. Port to 16 bit DOS. Allow to set options in stdio mode. Bugfix dos2unix MAC mode: don't change DOS line endings.
2010-02-16: Version 5.0. Dos2unix and Unix2dos have been bundled in a single package.
German translations have been added.
Dos2unix -l --newline also works in MAC mode.
Unix2dos also got option -l, --newline.
Added MAC mode to Unix2dos: Convert Unix line endings to Mac line endings.
Cleanup of messages and manual.
2010-01-24: Version 4.1.2 preserves file modes in new file mode.
2010-01-21: Version 4.1.1 fixes a compilation problem on FreeBSD.
2009-12-28: Version 4.1 automatically skips binary and non-regular files, and the ISO mode has been cleaned up (see ChangeLog).
2009-12-21: Version 4.0.1 adds a port to OS/2 Warp. Two wrong conversions in ISO mode have been fixed. The manual page has been updated.
2009-12-15: Version 4.0 adds internationalisation (Native Language Support, NLS). A Dutch translation has been added. Ports to Windows and DOS have been made. The problem in DOS/Windows stdio mode has been fixed. The manual has been updated.

Recursive conversion of files
To recursively convert text files in a directory tree, use dos2unix in combination with the 'find' and 'xargs' commands. For instance to convert all .txt files under the current directory type:
find . -name *.txt |xargs dos2unix
Windows users can get find and xargs from the findutils package for Windows from the ezwinports project at http://sourceforge.net/projects/ezwinports/files/.
