Git: Delete Last Commit

Many times like you, even professional programmers do mistakes. A lot of times it happens that you commit something junk in hurry and then you start looking out for reverting it back. Like you even I have done such mistakes many times and finally I thought to write down a few useful git commands which will help me to revert back to stable copy of project.

Using ‘git reset’

So, if you have committed something junk, not useful but you have not pushed it to remote repository then you can go with

git reset --soft HEAD~1

git reset‘ command will reset your current commit. The ‘HEAD~1‘ mentioned here is nothing but shorthand for your last commit and the ‘–soft’ option specified in the command will keep all the changes in working copy.

Consider we have following three commits,

Git Commits Screenshot

and now we want to delete our last commit i.e. commit 3. So if we use the git reset –soft HEAD~1 command then result will be,

Git reset commit result

Note, since we have done soft reset, all changes which we have done in commit 3 are now in working copy.

If you want to hard reset your repository then you can go for ‘–hard’ instead of ‘–soft‘. This option will delete your last commit and all changes made including working copy.

If you want to move back to specific commit then you can use SHA-1 id of the commit at place of the HEAD~1. Example if you want to move commit whose SHA-1 if is 3518a64 then you can use

git reset --soft 3518a64

Note here we are using –soft, so all the changes made will be preserved.

Using ‘git revert’

The ‘git reset’ command works only when you have committed something and it is not pushed to remote repository. But if you have committed something and pushed it to remote repository then rather than ‘git reset‘ you have to go for ‘git revert‘. simply use

git revert HEAD

and then push or sync your repository. You will see that a new commit is created which do not include anything introduced by accidental change.

Considering same example as above, we are having three commits as follows

Git Commits Screenshot

and consider we have pushed everything to remote repository. Now if we use ‘git revert HEAD‘ then the result will be…

Git revert commit result

Now if you go through your working copy, you will find that all the changes made in last junk commit are discarded.

Working With wp_register_script()

WordPress allows you to register your own script files with theme. This allows you to link the script file to WordPress generated page according to the dependencies and at right time. The traditional way of including scripts, i.e. by adding <script> tag in head or footer have some drawbacks. In traditional way, we hardcode the script and load it every time with page, even though it is not needed. But once you register the script with theme, it can be loaded dynamically. This allows you to improve your performance and make your website more faster.

So how to register a script?

Quite simple. Just use following syntax for registering your scripts.

<?php wp_register_script( $handle, $src, $deps, $ver, $in_footer ); ?>



‘handle’ is nothing but name of your script. You can give any name to your script but make sure that they are unique throughout your theme. No two scripts can have same name.


‘src’ is the url to your script. You can pass any url as parameter. Example: you can use “//” for registering Angular JS.


If your script depends on other scripts then you can specify all those other scripts in an array. This parameter will make sure that all the dependent scripts are loaded before this script.


‘ver’ specifies version number and it is added in your query string. If you have not specified the version number or specified it as ‘false’ then by default your current version number of WordPress will be added. If you set is as ‘null’ then no version number will be added to your query string. I would like to suggest you to set it as null which will help you to improve performance.


If you specifies this parameter as ‘true’ then script will be loaded in footer. For proper functioning of this parameter you will need wp_footer() hook in your theme at appropriate place. If you do not set this parameter then the script will be loaded in <head> of your theme.

How to use registered script in your theme?

To use your registered script in you have to use wp_enqueue_script(). Simply pass name of your script i.e. handle as parameter and WordPress will take care of rest.

Say we have ‘ankurcus‘ as handle for our registered script the we will use following line to load ‘ankurcus‘ with our theme.

<?php wp_enqueue_script('ankurcus'); ?>

That’s all. Now you have learned to register your custom scripts with WordPress and use them in your theme.
