Git Revert
revertje příkaz, který používáme, když chceme převzít předchozí commita přidat jej jako nový commit, přičemž logzůstane zachován.
Krok 1: Najděte předchozí commit:
Krok 2: Použijte jej k vytvoření nového commit:
Udělejme nový commit, kde jsme "omylem" smazali soubor:
Příklad
git commit -m "Just a regular update, definitely no accidents here..."
[master 16a6f19] Just a regular update, definitely no accidents here...
1 file changed, 0 insertions(+), 0 deletions(-)
delete mode 100644 img_hello_git.jpgNyní máme část naší commithistorie, ke které se chceme vrátit. Zkusme to udělat s revert.
Git Revert Find Commit in Log
Nejprve musíme najít bod, ke kterému se chceme vrátit. K tomu musíme projít
log.
Abychom se vyhnuli velmi dlouhému seznamu protokolů, použijeme
--onelinemožnost, která zobrazuje pouze jeden řádek na potvrzení:
- Prvních sedm postav
commit hash - a
commit message
Pojďme tedy najít bod, který chceme revert:
Příklad
git log --oneline

Git Revert HEAD
We revert the latest commit using git
revert HEAD (revert the latest change, and then
commit), adding the option
--no-edit to skip the commit message editor (getting the default
revert message):
Example
git revert HEAD --no-edit
[master e56ba1f] Revert "Just a regular update, definitely no accidents here..."
Date: Thu Apr 22 10:50:13 2021 +0200
1 file changed, 0 insertions(+), 0 deletions(-)

git revert HEAD~x (x being a number. 1 going back one more, 2 going back two more, etc.)
On the next page, we'll go over git reset, which brings the repository back to an earlier state in the commits without
making a new commit.
