![]() ![]() ![]() Install Wine Mac Lion OS X 10.7 / 10.8 Mountain Lion JanuFuad NAHDI Wine (Windows Emulator) is a free and open-source application that aims to allow programs / softwares written for Microsoft Windows to run on Unix-like operating system such as Linux, BSD, Solaris and Mac OS X. Window files use the same format as Dos, where the end of line is signified by two characters, Carriage Return or CR or r followed by Line Feed or LF or n. Dos2unix and unix2dos commands Sometimes, you will need to move files between windows and unix systems. Problem is, this command is not available in the ZOS/UNIX environment. Specifically, changing the end of line marker on each line. I've read that there is a UNIX2DOS command in the Unix environment that will convert from a 'Unix' format to a 'Dos' format. A few DOS code pages can be converted to Unix Latin-1. Besides line breaks Dos2unix can also convert the encoding of files. Nowadays Mac OS uses Unix style (LF) line breaks. In Mac text files, prior to Mac OS X, a line break was single Carriage Return (CR) character. In Unix text files a line break is a single character: the Line Feed (LF). Written to fill a need for a Windows-based program that modifies line-endings on large numbers of text files after they have undergone OCR processig on Unix systems. Unix2Dos is superior to the built in unix command that is incapable of processing more than 10000 or so files without running out of command space. It is an update of Benjamin Lin's implementations.
