Git Diff Command

A Git Diff Command is a version control command that displays code differences between git commits, working directorys, or staging areas.

• AKA: git diff, Git Difference Command, Git Change Display Command, Git Comparison Command.
• Context:
  • It can typically compare Working Directory Changes against Staging Area.
  • It can typically show Line Additions, Line Deletions, and Context Lines.
  • It can typically generate Unified Diff Format or Context Diff Format output.
  • It can often highlight Word-Level Changes within modified lines.
  • It can often filter by File Path Patterns or File Types.
  • It can often display File Permission Changes and File Mode Changes.
  • It can support Binary File Comparison with summary information.
  • It can range from being a Summary Diff Display to being a Detailed Diff Display, depending on its output verbosity.
  • It can range from being a Colored Diff Output to being a Plain Diff Output, depending on its display format.
  • It can range from being a File-Level Diff to being a Line-Level Diff, depending on its granularity level.
  • It can range from being a Cached Diff to being a Working Tree Diff, depending on its comparison target.
  • ...
• Examples:
  • Basic Git Diff Usage, such as:
    • `git diff` for working directory changes.
    • `git diff --cached` for staged changes.
  • Commit Comparison Usage, such as:
    • `git diff HEAD~1` for last commit changes.
    • `git diff branch1..branch2` for branch differences.
  • Advanced Diff Usage, such as:
    • `git diff --word-diff` for word-level change display.
    • `git diff --stat` for change summary statistics.
  • ...
• Counter-Examples:
  • Git Status Command, which lists modified files but doesn't show content differences.
  • Git Log Command, which shows commit history but not detailed changes.
  • Git Format-Patch Command, which creates patch files rather than displaying differences.
