How to run multiple Unix commands in one time?

Question

I\'m still new to Unix. Is it possible to run multiple commands of Unix in one time? Such as write all those commands that I want to run in a file, then after I call that file,

bash filename

This will run the commands in sequence. If you want them all to run in parallel (i.e. don't wait for commands to finish) then add an & to the end of each line in the file
