Git add and commit in one command

Question

Is there any way I can do

git add -A
git commit -m \"commit message\"

in one command?

I seem to be doing those two commands a lot,

Answer 1

I do a shell

#!/bin/sh

clear

git add -A 
git commit -a -m "'$*'"

save for example git.sh and later call:

sh git.sh your commit message
