How do I get last commit date from git repository?

Question

I need the last commit date in git. This means the latest update date in my program.

I used the command : $ git log -1 but this command will give me the date from the local repository. Rather I need date from remote repository.

I tried some commands as follow.

git log -n 1 origin/Sprint-6.
git rev-parse --verify HEAD

Answer 1

The following command will be helpful:

git log -1 --format=%cd 

This will print the latest change date for one file. The -1 shows one log entry (the most recent), and --format=%cd shows the commit date. See the documentation for git-log for a full description of the options.

Get the last commit date:

You want the "repository wide last commit date for a given git user and git project, for a given branch.

The date you're after is the latest date shown when you visit your repo and go to commits -> master for example:

https://github.com/sentientmachine/TeslaAverageGainByMonthWeekDay/commits/master

The top of the page shows the latest commit date.

Get the last local commit date in git using terminal

Use git help log for more info on format codes to pass to --format to tell git log what kind of data to fetch.

The last commit date in git:

git log -1 --format="%at" | xargs -I{} date -d @{} +%Y/%m/%d_%H:%M:%S
#prints 2018/07/18 07:40:52

But as you pointed out, you have to run that command on the machine that performed that last commit. If the last commit date was performed on another machine, the above command only reports local last commit... So:

Or Repository wide: Get the last git commit date

Same as above, but do a git pull first.

git pull; 
git log -1 --format="%at" | xargs -I{} date -d @{} +%Y/%m/%d_%H:%M:%S
#prints 2018/07/18 09:15:10

Or use git's JSON API:

git pulls on a schedule aren't cool because it's slow and you're banging the server with unnecessary network traffic. Just query the git rest api:

#assuming you're using github and your project URL is visible to public:
# https://github.com/yourusername/your_repo_name

#then do:
curl https://api.github.com/repos/yourusername/your_repo_name/commits/master

That blasts you in the face with a screen full of json, so send it your favorite json parser and get the field called date:

curl https://api.github.com/repos/<your_name>/<your_repo>/commits/master 2>&1 | \
grep '"date"' | tail -n 1
#prints "date": "2019-06-05T14:38:19Z"
