Git - Learning to fiddle with it properly

I've been using Git on and off for about two years, but have mostly been lazy and depended upon the Github Desktop: -


especially for commits and pushes.

I'm using an Enterprise Github instance, as hosted by IBM - which is nice.

However, of course, I still have a set of local GIt repositories, native to my Mac, as per this example: -

/Users/davidhay/Git/WASScripts

So, in the interest of self-enablement, I dug further into using the command-line interface.

The first trick was to create a Personal Access Token: -


which I could use in lieu of a password, when connecting from the command-line to Git.

Having generated a token, I then did some tinkering: -

Change to my local Git repository, for WebSphere Application Server (WAS) scripts

cd ~/Git/WASScripts

Create a file

touch snafu.txt

Add the file to the local Git repo

git add snafu.txt

Commit the changes to  Enterprise Github

git commit

[master 92f77cd] Adding snafu.txt
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 snafu.txt


This brings up vi and requires me to add some comments; I then save these using :wf or [Escape][z][z] 

Push the changes to Enterprise Github

git push

Counting objects: 3, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (2/2), done.

   64af5d4..92f77cd  master -> master


Validate that the file now appears in Github Enterprise


Remove the file locally

git rm snafu.txt

rm 'snafu.txt'

Commit the changes to Enterprise Github

git commit

[master 4773e77] Removing snafu.txt
 1 file changed, 0 insertions(+), 0 deletions(-)
 delete mode 100644 snafu.txt

Validate that we're in sync

git commit

On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean


Validate that the file has now been removed from Github Enterprise


Nice !

Amongst many other fine sources, I did find this to be immensely useful: -
