What Others Think

Hmm... Useful, but a bit long-winded. First, "history" take an option -- the number of lines to display. So use history 1 and you don't need tail. Second you use two sed clauses when only one is needed: sed 's/^\s*[0-9]\+\s\+\(.*\)[;&|]\s*alert$/\1/' Search for whitespace, number, whitespace (anything) divider ( ; & or | ) and "alert" Then replace with the bracketed clause. alias alert='notify-send --urgency=low -i "$([ $? = 0 ] && echo terminal || echo error)" "$(history 1|sed '\''s/^\s*[0-9]\+\s\+\(.*\)[;&|]\s*alert$/\1/'\'')"'
