To show the list of commits that are reachable from the current commit but excluding commits that are reachable from another specified commit, you can use the git log command in combination with the --not option.
Here's the command structure:
git log --not <commit-hash> --oneline
Explanation:
1. Replace <commit-hash>: Replace <commit-hash> with the hash of the commit you want to exclude. If you want to exclude multiple commits, you can list them separated by spaces.
2. Current Commit: By default, git log will consider the current commit (HEAD) as the starting point.
3. --not Option: The --not option tells Git to exclude commits reachable from the specified commit hash.
4. --oneline Option: This option formats the log output to show a summary of each commit in a single line, making it easier to read.
Example:
Assuming you want to exclude commits reachable from abc1234, you would run:
git log --not abc1234 --oneline
This command will give you a list of commits that are reachable from your current commit but are not reachable from the commit with hash abc1234.
Additional Note:
If you need to exclude commits from multiple branches or commits, you can add those commits like so:
git log --not <commit-hash-1> --not <commit-hash-2> --oneline
Replace <commit-hash-1> and <commit-hash-2> with the actual commit hashes you want to exclude. This will provide you with all the reachable commits from the current commit while excluding those specified.
