What is the difference between sh and ./

Question

When given a binary in a terminal, you can launch it via

sh myapp

or

./myapp

Are there any other ways to launch the app? Is there any difference between sh and ./ ? What do they denote/stand for?

Answer 1

There are differences between them.

Let's look at the first one:

sh myapp

It opens myapp in sh. The command may not work with binaries as muru said.

Let's look at the second one:

./myapp

It tells the shell to open myapp. The shell gets the app set as preferred and then sends to the application command to open the app.

I remember that the sh way doesn't require executive rights. (may someone who is sure confirm?)
