About:
dos2unix is a command-line utility designed to convert plain text files between DOS/Windows, UNIX/Linux, and Mac line ending formats. It handles the transformation of CR+LF (Carriage Return + Line Feed) sequences to and from the LF (Line Feed) standard used on Unix-like systems. This ensures cross-platform compatibility for scripts, configuration files, and source code.
Key Features:
  • Batch conversion of multiple files and directories
  • Preserves original file timestamps or updates them as needed
  • In-place file modification with optional backup creation
  • Handles mixed-format files gracefully
Use Cases:
  • Fixing shell scripts created on Windows that fail to run on Linux due to CRLF line endings
  • Preparing text data or log files on Linux for use in Windows-based applications
  • Cleaning up source code repositories to maintain consistent line endings across platforms
Alternatives:
  • tr – Standard Unix tool that can remove CR characters but lacks dos2unix's file handling and backup features.
  • sed – Stream editor that can perform replacements but requires more complex commands for safe conversion.
