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.
