Flip - Convert text file line endings between Unix and DOS formats

Post date: March 2, 2009, 07:03 Category: System Views: 2588 Comments
Tutorial quote: This program converts line endings of text files between MS-DOS and **IX formats. It detects binary files in a nearly foolproof way and leaves them alone unless you override this. It will also leave files alone that are already in the right format and preserves file timestamps.User interrupts are handled gracefully and no garbage or corrupted files left behind. ‘flip’ does not convert files to a different character set, and it can not handle Apple Macintosh line endings (CR only). For that (and more), you can use the ‘recode’ program (package ‘recode’).
