# !!! TIP:

# '2>/dev/null/'

#- "In the *nix world, output to the command line is generally of two flavors, stdout (standard # # output) and stderr      # (standard error). Well-behaved programs send their normal output to stdout and any warnings or error # # messages to #stderr. So, if you want errors/warnings to disappear, you can usually accomplish this by throwing away any    # messages on #stderr using the output redirection 2>/dev/null. (In English, that's "redirect (>) the second output channel
# (2, which is stderr) to /dev/null (which just throws away everything sent there)"."
