Comparing changes in commits to the current file by Git

Comparing changes in commits to the current file by Git

git diff specific file
git diff between local and remote file
git diff last commit
git diff file between branches
git compare local to remote
git diff head
git file compare tool
git diff filename

How can you show the differences of a file in the last 5 commits to the current uncommitted file by Git-show?

I made a change to my file which breaks my code. However, I do not know where the change is.

I would like to compare the current uncommitted files to the recent commit (HEAD), to the previous commit (^HEAD) and at least 3 commits deeper.

However, I do not know how you can do it efficiently.

In trying to see the changes of the five last commits of one file to the current file in the given branch, I unsuccessfully ran

git show next~5:handle_questions.php

Here is my cheat-sheet:

# uncommited file to HEAD
git diff <path>

# uncommited file to before last commit
git diff HEAD^ -- <path>

#last commit to before last commit
git diff HEAD^ HEAD -- <path>

#difference between HEAD and n-th grandparent
git diff HEAD~n HEAD -- <path>

#Another cool feature is whatchanged command
git whatchanged -- <path>

Git tutorial – comparing files with diff, The most common scenario to use diff is to see what changes you made after your last commit. Let's see how to do it. I opened the helloworld  Comparing commits. You can also compare two arbitrary commits in your repository or its forks on GitHub in a two-dot diff comparison. To quickly compare two commits or Git Object IDs (OIDs) directly with each other in a two-dot diff comparison on GitHub, edit the URL of your repository's "Comparing changes" page.


To see the diff between handle_questions.php in the working directory and in the repository 5 commits back, use:

$ git diff HEAD~5 handle_questions.php

git-diff Documentation, git-diff - Show changes between commits, commit and working tree, etc add -N" appear as an existing empty file in "git diff" and a new file in "git diff --cached". Comparing all changes. Invoking git diff without a file path will compare changes across the entire repository. The above, file specific examples, can be invoked without the ./path/to/file argument and have the same output results across all files in the local repo. Changes since last commit. By default git diff will show you any uncommitted


You can use git bisect to track down the commit which introduced a bug.

Comparing commits, You can also compare two arbitrary commits in your repository or its forks on GitHub in a two-dot diff comparison. To quickly compare two commits or Git Object IDs  You can also limit the comparison to a specific file or subdirectory by adding a path limiter: $ git diff HEAD -- ./lib That command will show the changes between your current working directory and the last commit (or, more accurately, the tip of the current branch), limiting the comparison to files in the 'lib' subdirectory.


If you know the file that the change was made in, you can also use git blame <path> - this will give you ahistory of each line of code in the following format:

SHA (Author Timestamp Line Number) code

Git Diff, These data sources can be commits, branches, files and more. This document will discuss common invocations of git diff and diffing work flow patterns. is often used along with git status and git log to analyze the current state of a Git repo. You can also compare files between two different commits. Every commit in Git has a commit id which you can get when you give git log. Then you can use the commit id if diff command like this. git diff 7eb2..e03 812a3f35. You can compare not just a single file, but all your changes at once.


From @db_ answer (but shown as an actual example)

I just want to see what difference there is between the current file and the last commit for just a single file.

git diff scripts/processQueue.php


-  if( filemtime( $filename ) < time() - 10 ) {
+  $filemtime=filemtime($filename);
+  if( $filemtime < time() - 10 && $filemtime> (time() - 86400)) 

Git Tutorial: Comparing Files With diff, A developer gives a tutorial on how use diff to see what changes developers have made after their last commit to their git repository. View the changes between any two versions by selecting both commits, then right-clicking and select Compare The diff view shows lines removed from the older commit and added in the new one. Use the git log command to view the commits that changed a file in your repo for your current branch.


Git Diff, The 'diff' command in Git will show you the same thing - the changes between On branch master # Changes to be committed: # (use "git reset HEAD <file>. git diff [<options>] [--] [<path>…. This form is to view the changes you made relative to the index (staging area for the next commit). In other words, the differences are what you could tell Git to further add to the index but you still haven’t.


git-diff - Show changes between commits, commit , current repository, git diff will compare the two files / directories. This behavior can be forced by --no-index. git diff [--options] --cached [<commit>] [--] [<path>. It can be helpful to see the changes between two sets of code; git diff lets us do this by comparing two Git references and outputting the differences between them. In this lesson, we show how to use git diff along with the --stat, --cached, HEAD, origin/master, file(s)/dir(s) options.


Git History Diff, --staged is a synonym of --cached. git diff [<options>] <commit> [--] [<path>. -N" appear as an existing empty file in "git diff" and a new file in "git diff --cached". In order to see the commit differences between two branches, use the “git log” command and specify the branches that you want to compare. $ git log branch1..branch2 Note that this command won’t show you the actual file differences between the two branches but only the commits.
