- | = Pipe operator -> combines input and output redirection so that the output of one command is immediately used as the input for another.
             Ex: ls -lh | more
- comanda < fisier =  redirectioneaza outputul comenzii spre un fisier
- comanda << fisier = appends the new data to the end of the file
- Command Substitution = another way of using the output of one command as an argument to another. Ex: ls $(pwd) <-> pwd | ls
  The construction using the $ operator is distinctive in that the command in parentheses is executed in a subshell. 
  Instead of using the $() construction, you can also use backticks. Ex: ls `pwd`
- gnome-terminal = to launch a new terminal
