Git resetten

resetis het commando dat we gebruiken als we de repository terug willen verplaatsen naar een vorige commit, waarbij we alle wijzigingen die daarna zijn gemaakt willen negeren commit.

Stap 1: Zoek de vorige commit:

Git Reset Stap 1

Stap 2: Verplaats de repository terug naar die stap:

Git Reset Stap 2

Na het vorige hoofdstuk hebben we een deel in onze commitgeschiedenis waar we naar terug kunnen gaan. Laten we dat proberen met reset.


Git Reset Zoek Vastleggen in Logboek

Allereerst moeten we het punt vinden waarnaar we willen terugkeren. Om dat te doen, moeten we door de log.

Om de erg lange loglijst te vermijden, gaan we de --onelineoptie gebruiken, die slechts één regel per commitvertoning geeft:

  • De eerste zeven tekens van de commit hash- dit is waar we naar moeten verwijzen in ons reset-commando.
  • decommit message

Dus laten we het punt vinden dat we willen reset:

Voorbeeld

git log --oneline
e56ba1f (HEAD -> master) Revert "Just a regular update, definitely no accidents here..."
52418f7 Just a regular update, definitely no accidents here...
9a9add8 (origin/master) Added .gitignore
81912ba Corrected spelling error
3fdaa5b Merge pull request #1 from w3schools-test/update-readme
836e5bf (origin/update-readme, update-readme) Updated readme for GitHub Branches
daf4f7c (origin/html-skeleton, html-skeleton) Updated index.html with basic meta
facaeae (gh-page/master) Merge branch 'master' of https://github.com/w3schools-test/hello-world
e7de78f Updated index.html. Resized image
5a04b6f Updated README.md with a line about focus
d29d69f Updated README.md with a line about GitHub
e0b6038 merged with hello-world-images after fixing conflicts
1f1584e added new image
dfa79db updated index.html with emergency fix
0312c55 Added image to Hello World
09f4acd Updated index.html with a new line
221ec6e First release of Hello World!

We willen terug naar de commit: 9a9add8 (origin/master) Added .gitignore, de laatste voordat we met dingen begonnen te rotzooien.



Git resetten

We reset our repository back to the specific commit using git reset commithash (commithash being the first 7 characters of the commit hash we found in the log):

Example

git reset 9a9add8

Now let's check the log again:

Example

git log --oneline
9a9add8 (HEAD -> master, origin/master) Added .gitignore
81912ba Corrected spelling error
3fdaa5b Merge pull request #1 from w3schools-test/update-readme
836e5bf (origin/update-readme, update-readme) Updated readme for GitHub Branches
daf4f7c (origin/html-skeleton, html-skeleton) Updated index.html with basic meta
facaeae (gh-page/master) Merge branch 'master' of https://github.com/w3schools-test/hello-world
e7de78f Updated index.html. Resized image
5a04b6f Updated README.md with a line about focus
d29d69f Updated README.md with a line about GitHub
e0b6038 merged with hello-world-images after fixing conflicts
1f1584e added new image
dfa79db updated index.html with emergency fix
0312c55 Added image to Hello World
09f4acd Updated index.html with a new line
221ec6e First release of Hello World!

Warning: Messing with the commit history of a repository can be dangerous. It is usually ok to make these kinds of changes to your own local repository. However, you should avoid making changes that rewrite history to remote repositories, especially if others are working with them.


Git Undo Reset

Even though the commits are no longer showing up in the log, it is not removed from Git.

If you know the commit hash you can reset to it:

Example

git reset e56ba1f

Now let's check the log again:

Example

git log --oneline
e56ba1f (HEAD -> master) Revert "Just a regular update, definitely no accidents here..."
52418f7 Just a regular update, definitely no accidents here...
9a9add8 (origin/master) Added .gitignore
81912ba Corrected spelling error
3fdaa5b Merge pull request #1 from w3schools-test/update-readme
836e5bf (origin/update-readme, update-readme) Updated readme for GitHub Branches
daf4f7c (origin/html-skeleton, html-skeleton) Updated index.html with basic meta
facaeae (gh-page/master) Merge branch 'master' of https://github.com/w3schools-test/hello-world
e7de78f Updated index.html. Resized image
5a04b6f Updated README.md with a line about focus
d29d69f Updated README.md with a line about GitHub
e0b6038 merged with hello-world-images after fixing conflicts
