If you have made changes to your files in Git and then discarded them, you can use the "git checkout" command to revert the changes back to the last saved version. This command allows you to revert specific files or the entire repository back to its previous state. By using this command, you can undo any changes that were previously discarded and restore your files to their previous state in Git.
How to discard untracked files in git?
To discard untracked files in Git, you can use the git clean command.
To remove untracked files only:
1
|
git clean -n
|
This command will show you a list of untracked files that will be removed.
To actually remove the untracked files, you can run:
1
|
git clean -f
|
Be cautious when using the git clean command, as it permanently removes untracked files and cannot be undone. Be sure to double check the list of untracked files before running the command.
How to undo a git reset --soft?
If you have performed a git reset --soft and want to undo it, you can use the following steps:
- Find the commit hash that you were at before the git reset --soft by using the git reflog command.
- Use the git reset --soft command to reset back to that specific commit.
- If you want to completely undo the git reset --soft and go back to the state before the reset, you can use the git reset --hard command instead.
Keep in mind that using the git reset --hard command will reset all changes and uncommitted work, so make sure to back up any important changes before doing so.
What is the git checkout command used for?
The git checkout command is used to switch between different branches in a Git repository. It can be used to switch to an existing branch, create a new branch, discard changes in the working directory, and more.
How to discard changes made by a specific author in git?
To discard changes made by a specific author in Git, you can use the following steps:
- Use the git log command to find the commit(s) made by the specific author whose changes you want to discard. Note down the commit hash(es) of the relevant commit(s).
- Use the following command to revert the changes made by the specific author:
1
|
git revert -n <commit-hash>
|
This command creates a new commit that undoes the changes made in the specified commit, but leaves the changes in your working directory. The -n flag is used to prevent Git from automatically committing the changes.
- Use the git status command to see the changes that have been reverted in your working directory.
- Finally, use the git reset command to discard the changes in your working directory:
1
|
git reset --hard
|
This command will discard all changes in your working directory and reset it to the state of the most recent commit.
Note: Be careful when using the git revert and git reset commands, as they can permanently delete changes and cannot be undone. It is recommended to create a backup or branch before making any changes.
How to undo a git reset --hard?
If you have made a git reset --hard and want to undo it, you can follow these steps:
- Find the commit hash that points to the state of the repository before the reset --hard command was executed. You can use git reflog command to see a log of all the recent actions in the repository and find the commit you want to restore.
- Once you have identified the commit hash, you can use the git reset command to move the HEAD pointer back to that commit. For example, if the commit hash is abcdef, you can use the following command: git reset --hard abcdef
- After running the command, your working directory should be restored to the state it was in before the reset --hard command was executed.
It's important to note that using git reset --hard can be destructive and may result in losing changes permanently, so it's best to use it with caution.
