GNU diff is a command-line tool for comparing the contents of two files or directories and highlighting the differences between them. It is part of the GNU Utilities software suite and is widely available on Unix-based operating systems, including Linux and macOS.
The main purpose of GNU diff is to help users identify differences between two text files or directories. It does this by analyzing the contents of each file or directory and highlighting the lines or sections that differ. Users can specify various options to customize the output of GNU diff, such as ignoring whitespace differences or suppressing certain types of changes.
GNU diff is a powerful and flexible tool that is commonly used in software development, system administration, and other technical fields. It can help users detect changes in code, configuration files, and other important data, and can be integrated into automated workflows to streamline various tasks.
GNU diff works by analyzing the contents of two files and identifying the lines that differ between them. It does this by performing a line-by-line comparison of the files, looking for matching or non-matching lines.
When GNU diff encounters two lines that are different, it generates a "diff" output that shows the changes between the two lines. The output can be customized using various options, such as specifying the number of context lines to include or ignoring certain types of differences, such as whitespace.
GNU diff also supports comparing entire directories, rather than just individual files. In this case, it performs a recursive comparison of the directories and generates output that shows the differences between corresponding files in the two directories.
Overall, GNU diff is a powerful and flexible tool that provides a wide range of options for comparing files and directories. It is commonly used in software development, system administration, and other technical fields to help users detect changes and manage complex data sets.
