Git Revert Some Changes

Question :  The Nautilus application development team was working on a git repository /usr/src/kodekloudrepos/demo present on Storage server in Stratos DC. However, they reported an issue with the recent commits being pushed to this repo. They have asked the DevOps team to revert repo HEAD to last commit. Below are more details about the task:

In /usr/src/kodekloudrepos/demo git repository, revert the latest commit ( HEAD ) to the previous commit (JFYI the previous commit hash should be with initial commit message ).

Use revert demo message (please use all small letters for commit message) for the new revert commit. 

Please Note :-  Perform the below commands based on your question  server,  user name & other details might differ . So please read task carefully before executing. All the Best 👍

Solution:  

1. At first login on storage server  & switch to root user

thor@jump_host /$ ssh natasha@ststor01 The authenticity of host 'ststor01 (172.16.238.15)' can't be established. ECDSA key fingerprint is SHA256:IxwAD3ZVWxJeoVZGlhqWNAp/2Waue9JvaV7Hz6hyyfg. ECDSA key fingerprint is MD5:87:7c:77:5f:04:db:fa:a3:35:82:e6:d9:d4:f0:1c:35. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'ststor01,172.16.238.15' (ECDSA) to the list of known hosts. natasha@ststor01's password: [natasha@ststor01 ~]$ sudo su -  We trust you have received the usual lecture from the local System Administrator. It usually boils down to these three things:      #1) Respect the privacy of others.     #2) Think before you type.     #3) With great power comes great responsibility.  [sudo] password for natasha: [root@ststor01 ~]#

2. Check repo  git status
