Simple shell script for changing the date of the last local commit. Useful for old projects that have been build without a version control system, but sorta have their history preserved with snapshots or something like that. 🙃 The script deliberately only focuses on the last local commit to avoid big risk with your git history.

• This script only works on the last local commit of the current branch
  • This script has no effect on commits that have already been pushed

• Git for Windows
  • Required for local git VCS
  • Required for BASH emulation on Windows

Clone this repository with git.

git clone https://github.com/nickbeen/git-date.git

For easy usage, create an alias for the script named e.g. git-date.

1. Add file(s) to git or modify existing file(s) in your git project
2. Create a new commit with a useful commit message
3. Run git-date.sh to change the date of the commit

Usage: ./git-date.sh <commitDate>

Operands:
  <commitDate>    Date in git internal format, RFC 2822 format, ISO 8601 format or human-centric date format.

The script accepts one operand, the date, in the following formats.

Ommiting the date will result in an error with exit code 1.

Error: operand commitDate is required

To run the script in Windows:

"%ProgramFiles%\Git\bin\bash.exe" git-date.sh '2019-11-15T13:37'

To run the script in Linux:

./git-date.sh '2019-11-15T13:37:17'

When successful, the script returns the commit log of the last commit.
