For us sysadmins it is important to create scripts on the fly and make things work. By working in an ad-hoc way, our scripts will get lost, not cured and especially not searchable.
Initial tools setup
For every single script it is a better idea to integrate or put all its relative files in a separate folder. Then put all these folders in a single one named: scripts.
After installing TortoiseGIT it is a good idea to go with the First Start wizard.
Select the defaults and in the “configure user information” screen input your name and a valid email address.
The next thing to do is to integrate all your scripts in a GIT repo. With the help of TortoiseGIT this can be easily achieved with only the right click of the mouse
And you are done with the repository creation.
After each working sessions it is a good idea to commit your work. With TortoiseGIT again this can be easily done by a mouse right-click.
Then fill out the commit screen with an appropriate message and then click commit
The commit confirmation screen will show up.
Do the same steps (commit) after each coding session to save your work and your coding history.
Pushing code remotely
After working locally, you might consider storing your code in a server repo. A good one is at GitLab which offers private repos for free.
