Find and restore a deleted file in a Git repo

Source URL

Find the last commit that affected the given path. As the file isn’t in the HEAD commit, this commit must have deleted it.

git rev-list -n 1 HEAD -- <file_path>

Then checkout the version at the commit before, using the caret (^) symbol:

git checkout <deleting_commit>^ -- <file_path>

Or in one command, if $file is the file in question.

git checkout $(git rev-list -n 1 HEAD -- "$file")^ -- "$file"

GIT clone repo across local file system

Source URL

This worked for me:

git clone file:////<host>/<share>/<path>

edit: For example, if your main machine has the IP 192.168.10.51 and the computer name main, and it has a share named code which itself is a git repository, the both of the following commands should work equally:

git clone file:////main/code

git clone file:////192.168.10.51/code

If the git repository is in a subdirectory, simply append the path.

Change commit messages of past Git commits

Source URL

To change a commit message of the most recent (unpushed) commit, you can simply use

git commit --amend -m 'new message'

To change messages of (unpushed) commits further in the past:

git rebase -i [COMMIT BEFORE THE FIRST YOU WANT TO EDIT]

Mark all messages to be changed with “edit”. Git will start the rebasing and stop at every marked commit. For each of those, do a

git commit --amend -m 'new message'git rebase --continue

github - How do I delete a Git branch both locally and remote?

Source URL

git push origin --delete <branchName>

clean unstaged files in Git

git clean -fd

How to grep (search) committed code in the git history?

Source URL

To search for commit content (i.e., actual lines of source, as opposed to commit messages and the like), what you need to do is:

git grep <regexp> $(git rev-list --all)

Updates: git rev-list --all | xargs git grep expression will work if you run into an “Argument list too long” error

Applying .gitignore to committed files

Source URL

  1. Edit .gitignore to match the file you want to ignore
  2. git rm --cached /path/to/file

Git gitignore syntax

A leading slash matches the beginning of the pathname. For example, “/*.c” matches “cat-file.c” but not “mozilla-sha1/sha1.c”.
