How can I view a git log of just one user's commits?

Question

When using git log, how can I filter by user so that I see only commits from that user?

Solution

This works for both git log and gitk - the 2 most common ways of viewing history. You don't need to use the whole name.

git log --author="Jon"

will match a commit made by "Jonathan Smith"

git log --author=Jon

and

git log --author=Smith

would also work. The quotes are optional if you don't need any spaces.

Add --all if you intend to search all branches and not just the current commit's ancestors in your repo.

You can also easily match on multiple authors as regex is the underlying mechanism for this filter. So to list commits by Jonathan or Adam, you can do this:

git log --author="\(Adam\)\|\(Jon\)"

In order to exclude commits by a particular author or set of authors using regular expressions as noted in this question, you can use a negative lookahead in combination with the --perl-regexp switch:

git log --author='^(?!Adam|Jon).*$' --perl-regexp

Alternatively, you can exclude commits authored by Adam by using bash and piping:

git log --format='%H %an' | 
  grep -v Adam | 
  cut -d ' ' -f1 | 
  xargs -n1 git log -1

If you want to exclude commits commited (but not necessarily authored) by Adam, replace %an with %cn. More details about this are in my blog post here: http://dymitruk.com/blog/2012/07/18/filtering-by-author-name/

OTHER TIPS

git log --author="that user"

On github there is also a secret way...

You can filter commits by author in the commit view by appending param ?author=github_handle. For example, the link https://github.com/dynjs/dynjs/commits/master?author=jingweno shows a list of commits to the Dynjs project

git help log

gives you the manpage of git log. Search for "author" there by pressing / and then typing "author", followed by Enter. Type "n" a few times to get to the relevant section, which reveals:

git log --author="username"

as already suggested.

Note that this will give you the author of the commits, but in Git, the author can be someone different from the committer (for example in Linux kernel, if you submit a patch as an ordinary user, it might be committed by another administrative user.) See Difference between author and committer in Git? for more details)

Most of the time, what one refers to as the user is both the committer and the author though.

To pull more details - (Here %an refers to author)

Use this :-

git log --author="username" --pretty=format:"%h - %an, %ar : %s"

cat | git log --author="authorName" > author_commits_details.txt

This gives your commits in text format.

You can even abbreviate this a bit by simply using part of the user name:

git log --author=mr  #if you're looking for mrfoobar's commits

If you want to filter your own commits:

git log --author="<$(git config user.email)>"

try this tool https://github.com/kamranahmedse/git-standup

Usage

```bash
$ git standup [-a <author name>] 
              [-w <weekstart-weekend>] 
              [-m <max-dir-depth>]
              [-f]
              [-L]
              [-d <days-ago>]
              [-D <date-format>] 
              [-g] 
              [-h]
```

Below is the description for each of the flags

- `-a`      - Specify author to restrict search to (name or email)
- `-w`      - Specify weekday range to limit search to (e.g. `git standup -w SUN-THU`)
- `-m`      - Specify the depth of recursive directory search
- `-L`      - Toggle inclusion of symbolic links in recursive directory search
- `-d`      - Specify the number of days back to include
- `-D`      - Specify the date format for "git log" (default: relative)
- `-h`      - Display the help screen
- `-g`      - Show if commit is GPG signed or not
- `-f`      - Fetch the latest commits beforehand

If using GitHub:

go to branch
click on commits

it will show list in below format

branch_x: < comment> 
author_name committed 2 days ago

to see individual author's commit ; click on author_name and there you can see all the commit's of that author on that branch

Since the other question was (possibly wrongfully so?) locked, I will just put this here:

show authors with their commit counts:

git shortlog -nse

find all commits for specific USERNAME:

git log --author=USERNAME --oneline | awk '{print $1}' | xargs git show

Show n number of logs for x user in colour by adding this little snippet in your .bashrc file.

gitlog() {
    if [ "$1" ] && [ "$2" ]; then
       git log --pretty=format:"%h%x09 %C(cyan)%an%x09 %Creset%ad%x09 %Cgreen%s" --date-order -n "$1" --author="$2"
    elif [ "$1" ]; then
       git log --pretty=format:"%h%x09 %C(cyan)%an%x09 %Creset%ad%x09 %Cgreen%s" --date-order -n "$1"
    else
        git log --pretty=format:"%h%x09 %C(cyan)%an%x09 %Creset%ad%x09 %Cgreen%s" --date-order
    fi
}

alias l=gitlog

To show the last 10 commits by Frank:

l 10 frank

To show the last 20 commits by anyone:

l 20

You can use either = or "space". For instance following two commands return the same

git log --author="Developer1"

git log --author "Developer1"

My case: I'm using source tree, I followed the following steps:

Pressed CRL+3
Changed dropdown authors
Typed the name "Vinod Kumar"

Although, there are many useful answers. Whereas, just to add another way to it. You can also use

git shortlog --author="<author name>" --format="%h %s"

It will show the output in the grouped manner:

<Author Name> (5):
  4da3975f dependencies upgraded
  49172445 runtime dependencies resolved
  bff3e127 user-service, kratos, and guava dependencies upgraded
  414b6f1e dropwizard :- service, rmq and db-sharding depedencies upgraded
  a96af8d3 older dependecies removed

Here, total of 5 commits are done by <Author Name> under the current branch. Whereas, you can also use --all to enforce the search everywhere (all the branches) in the git repository.

One catch: git internally tries to match an input <author name> with the name and email of the author in the git database. It is case-sensitive.
