Commands

Examples:

# Restore a file from one of the past commits
git checkout aa9463b853dc removed-file.txt

# Git rebase - this is a BASE (commit) change for a branch commit
<changes>: git rebase master # the base change for the changes branch to the commit pointed to by the master branch

# git show
git show <commit>

# Differences in STAGE
git diff --cached

# Show log with differences
git log -p

# Show all git files
git ls-tree -r master --name-only

# Show commits with branches
git log --graph --all

# See which commits changed the contents of file.txt
git blame file.txt

# Delete remote branches
git push origin --delete feature/remotebranch

# Squash commits (top 5 into 1)
git rebase -i HEAD~5

# Delete large files in history (must be installed https://github.com/newren/git-filter-repo)
git filter-repo --path files/ --invert-paths # in this case, everything in the files/ folder is deleted

How to delete unnecessary things in history and push everything again in GitLab

- git clone
- git filter-repo --path files/ --invert-paths
- rm -Rf .git/logs .git/refs/original
- git gc --prune=all --aggressive
- deactivate Protected Branch
- in Push Rules we deactivate everything that prevents unregistered users from pushing
- git push origin --all --force
- if there are tags, more needs to be done "git push origin --tags --force"

git log

# The command shows commits issued branches in chronological order

# Find any commit that added or removed the string password
git log -S password

git log --graph

The command shows commits in chronological order within only one branch. Commits on neighboring branches can (and often will) be NOT IN CHRONOLOGICAL order. To see the correct order, use the --date-order option

git blame

If you need to find who wrote a specific code
