See changes to a specific file using git
GitGit SvnGit Problem Overview
I know that I can use the git diff
command to check the changes, but, as far as I understood, it is directory based. This means it gives all the changes of all files on the current directory.
How can I check only the changes in one specific file? Say, I have changed files file_1.rb
, file_2.rb
, ..., file_N.rb
, but I am only interested in the changes in the file file_2.rb
. How do I check these changes then (before I commit)?
Git Solutions
Solution 1 - Git
Use a command like:
git diff file_2.rb
See the git diff
documentation for full information on the kinds of things you can get differences for.
Normally, git diff
by itself shows all the changes in the whole repository (not just the current directory).
Solution 2 - Git
Another method (mentioned in this SO answer) will keep the history in the terminal and give you a very deep track record of the file itself:
git log --follow -p -- file
> This will show the entire history of the file (including history beyond renames and with diffs for each change). > > In other words, if the file named bar was once named foo, then git log -p bar (without the --follow option) will only show the file's history up to the point where it was renamed -- it won't show the file's history when it was known as foo. Using git log --follow -p bar will show the file's entire history, including any changes to the file when it was known as foo.
Solution 3 - Git
You can use gitk [filename]
to see the changes log
Solution 4 - Git
You can use below command to see who have changed what in a file.
git blame <filename>
Solution 5 - Git
You can execute
git status -s
This will show modified files name and then by copying the interested file path you can see changes using git diff
git diff <filepath + filename>
Solution 6 - Git
to list only commits details for specific file changes,
git log --follow file_1.rb
to list difference among various commits for same file,
git log -p file_1.rb
to list only commit and its message,
git log --follow --oneline file_1.rb
Solution 7 - Git
you can also try
git show <filename>
For commits, git show will show the log message and textual diff (between your file and the commited version of the file).
You can check git show Documentation for more info.
Solution 8 - Git
git diff filename
will give you added lines as + removed lines as -
Solution 9 - Git
Totally agree with @Greg Hewgill
And if you path includes spaces, you might use, try adding with apostrophe '
or `
git diff 'MyProject/My Folder/My Sub Folder/file_2.rb'
Solution 10 - Git
you can use tig :
sudo apt install tig
you just type : tig
in your console
you could have something like this , you could browse the commits and the local changes for every code line
Solution 11 - Git
Or if you prefer to use your own gui tool:
git difftool ./filepath
You can set your gui tool guided by this post: https://stackoverflow.com/questions/255202/how-do-i-view-git-diff-output-with-a-visual-diff-program
