little command saved the DOS
from having to put an '@' symbol in front of every line of the script to prevent the line from being displayed. Echo off
was always the first line of the BAT script, and therefore had to have an '@' symbol in front of it to stop it
from showing up on the screen.
In the days of DOS
and cute fuzzy file managers
this was the command that determined your level of l33t
ness. That, and it just made everything look so tidy
