- So let's have a look at the commands
that we have seen in this lesson.
It started with tee.
Tee, which is useful in pipes to make sure
that the output of the first command is sent to a file
as well as the pipe.
History, which is remembering everything that you are doing.
And don't forget history minus D if you did something that
you rather don't want to be remembered.
Alias, which allows you to create your own commands.
And then we have export,
which is exporting variables to sub shells as well.
Let's go check out the lab.
