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

You can compare files between two Git commits by specifying the name of the ref that refers to the commits you want to compare. A ref may be a commit ID or HEAD, which refers to the current branch. Let's compare two commits in our Git repository. The above command will perform a diff operation across our two commits.
To find out which files changed in a given commit, use the git log --raw command. It's the fastest and simplest way to get insight into which files a commit affects.
Diffing is a function that takes two input data sets and outputs the changes between them. git diff is a multi-use Git command that when executed runs a diff function on Git data sources. These data sources can be commits, branches, files and more.
I hope you're now able to compare the changes and recognize what we changed by looking at the diff's outcome. diff is a super powerful command that lets you compare changes in lots of ways. You can run the git diff HEAD command to compare the both staged and unstaged changes with your last commit.
Here's an example of a comparison between two repositories. As a shortcut, Git uses the ^ notation to mean "one commit prior." You can use this notation to compare a single commit or branch against its immediate predecessors. For example, 96d29b7^^^^^ indicates five commits prior to 96d29b7, because there are five ^ marks.
Check $ git log, then copy SHA id of 2 different commits and then run git diff command with those ids, for example: If you want the diff for a specific file, add the path to it at the end of the command. Also do a "git pull" to download the full tree info if the two commits are across diffrerent branches.
Fine, first we commit the staged changes by git commit -m "intro to cat and dog": Now, stage the "puppy" to "pup" change. Then, run the git diff --staged command which lists out the changes between the staged area and your last commit. A version – last commit containing the line my name is puppy in dog.txt
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> 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
