Method 1: Using git log

One of the very popular method to check all the Commit IDs and the changes done through this commit ID is by using git log command. If you simply run git log command then you will get list of all Commits done till now. But if you use git log -p command, then you will see all the Commits along with the changes done in each Commit. So output will be pretty long in this method. More on git log Man Page.

Please note that here I am running all the commands from my gcloud shell. You might be using some Linux based machine to commit your code. You can use any platform with git utility installed. It really doesn't matter.

 

Method 2: Using git show

Another very useful command that you can use is git show command. Using this method, you can check all the changes done on a Specific Commit ID. Syntax to use the command is git show <Commit ID>. You can get all the Commit ID from git log command. Here we are checking the list of changes for da475798411a3e2769219b4a7655b6821c4d1901 commit ID using git show command as shown below.

cyberithub@cloudshell:~$ git show da475798411a3e2769219b4a7655b6821c4d1901

Method 3: Using git diff

One more important command that you can use is git diff command to check the list of files modified between two Commit IDs. Syntax of this command is git diff --name-only <Start Commit ID>..<End Commit ID>. Here you need to provide start Commit ID and end Commit ID to know all the changes done between those two commit IDs. For example, we have randomly chosen start commit ID as 30b1d202d7e2727085d7dc8349ce8b0f67686f2d and end commit ID as da475798411a3e2769219b4a7655b6821c4d1901 from git log command as shown below. From the output you can see that between these two commits, cloudbuild.yaml and newfile are modified.
