Find Exit Code of Last Command Run On The Command Line

This is how you find the exist code of the last command you ran :

echo $?

results start

A [TODO: Code shorthand span ] is returned if there were no problems. Any non - 0 value represents an error.

For example, this will return [TODO: Code shorthand span ] (assuming [TODO: Code shorthand span ] runs properly) :

date
echo $?

results start

And this will return [TODO: Code shorthand span ] because running false returns it like an error would

false
echo $?

results start
