The default alias Alert is for the command
notify-send --urgency=low -i "$([ $? = 0 ] && echo terminal || echo error)" "$(history|tail -n1|sed -e '\''s/^\s*[0-9]\+\s*//;s/[;&|]\s*alert$//'\'')"
alert gives an notification with text Alert and an terminal icon.
Executing it with one param like
alert !!!!! gives notification with text Alert !!!!! and !!!!!.
So, what's the difference between simple
notify-send command and this complexed alias which uses notify-send, echo, history, tail and sed?
In which situations is this alias useful or was it just created for pun(Something like using
sudo sudo sudo sudo sudo apt-get install
