  • git add . *initiate the changes in the directory at a snapshot like a photo in the staging/staged area before it is finally updated to the remote repository with this git commit command.
  • git commit -m “[write in concise update message of that file]” ***make the language concise for other developers to access and understand…***
  • git push *this git command send changes from the local repository/environment to remote repository to be updated in git commits.
  • git init command can be done both locally on your computer or remotely/in the cloud on is best when starting up a new repository aka repo

  • We want to be able to track all the changes done by us and who made what changes when collaborations in our environment.
  • enter git config -l **-l means “list” to make sure our machine will display all settings, currently.
Saved Changes Visualization. We can check it with “git diff”, “git log”, “git status”
  • git log command tracks all the git commits starting with the most recent commit listed first in that descending order
  • git reflog command only track and highlights the one and most recent commit
  • git diff command aims at revealing comparisons with commits, branches, a single file across revisions of branches, etc. or just between what is a snapshot of commits between the working and staging areas
  • git status command reveals the state of the working directory and the staging area, except for the project’s history commits, so for that use git log command. Otherwise, the git status command displays staged, unstaged, and untracked files.
Git commands: git reflog, git log, git diff, git status
  • .gitignore tells us which file we do not want under version control
