Pipe multiple commands into a single command

Question

How can I pipe the stdout of multiple commands to a single command?

Example 1: combine and sort the output of all three echo commands:

echo zzz; ec         


        

Answer 1

In Windows it would be as follow: (echo zzz & echo aaa & echo kkk) | sort

Or if it is inside a batch file it can be mono line (like sample) as well as multiline:

(
 echo zzz
 echo aaa
 echo kkk
) | sort

Note: The original post does not mention it is only for Linux, so I added the solution for Windows command line... it is very useful when working with VHD/VHDX with diskpart inside scripts (echo diskpart_command) instead of the echo on the same, but let there the echo, there is also another way without echos and with > redirector, but it is very prone to errors and much more complex to write (why use a complicated prone to errors way if exists a simple way that allways work well)... also remember %d% gives you the actual path (very useful for not hardcoding the path of VHD/VHDX files).
