README.md

Commits log

Lists the last commit affecting a file across multiple repositories

Script written in answer of [https://stackoverflow.com/questions/55496873/git-find-last-time-a-file-was-modified-across-multiple-repos]

Requirements

Python3.6 or above is needed, along with the requests package (included in requirements.txt).

To install the requirements, you need to run:

pip install -r requirements.txt

Usage

Edit repos.txt to define the file you want to log and the list of repos you want to go through. The format is as follow:

• Path of the file, relative to the repository in the first line
• Each repository on the following lines

Example:

README.md
padawin/dotfiles
padawin/site
padawin/floodit-clone

Each line of repos.txt must be terminated with a Unix end of line (\n).

Then, run the script:

python3.6 log.py

The script will first output the erroring lines, then each commit line for each repo, sorted from the latest to the oldest.

Note

The commits are sorted by author date by default. If you want them sorted by committer date, call the script with committer as argument:

python3.6 log.py committer
