Question

What is the meaning of internal commands in Ubuntu Linux?

Answer 1

There are mainly two types of commands in Ubuntu Linux terminal- External Commands and internal commands.

Internal commands are the ones which are in-built and predefined in the linux shell and are not introduced by some external elements.

Internal commands are faster to execute and do not require a process for execution whereas external commands are the ones which are introduced by some external program and the system searches for the execution location every time they’re executed via the PATH variable.
