Git command to commit all changes including files removed or created

After making changes to files already tracked by `git` I usually do a: ``` git commit -a -m "a message describing what you did" ``` followed by ``` git push origin master ``` to commit and then push all changes to my Github account. The first command however does not work for commiting files either added or removed. To do that I would have to first type: ``` git add -A ``` as mentioned here: How to commit and push all changes, including deletes?. In this other question Git commit all files using single command the accepted answer indicates that the only way to apply the full commit (ie: including files added or removed, not only edited) and then the push is by combining them with the `&&` command like so: ``` git add -A && git commit ``` which in my case would look like: ``` git add -A && git commit -a -m "a message describing what you did" && git push origin master ``` Now for the question(s): is this large command correct? Is there a way to create a new `git` command to apply these three commands all at once? Furthermore: is this merging of commands recommended or discouraged? If so, please state the reason. Edit I immediately regret this decision: Edit last pushed commit's message.
