In linux environnement or windows when we are working with cmd bash Pshell and we are faced to write edit script each time … the use of notepad++ blocnot sublime may be a headach task each time swiping between terminal edit save , return to cmd ( unles we have 2 or 3 screen to project cmd in one and the editor in other screen .
if we modify directly in the cmd or bash we gain in term of efficiency and fastness
we can use the command line editors like vi it comes with bash
