Ich hab dafür eine Wrapperfunktion:

typo(){
# So often I make little stupid typos while firing away
# in the shell. They are very annoying, but it is too
# much trouble to fire up Emacs or nano to manually
# add an alias that would fix the problem. And typing
# the appropriate echo and append command is tedious and
# error prone. So, I whipped up a quick shell script which
# reads the two arguments provided, and constructs the appropriate
# echo command to create an alias that solves that typo.

    if [ $# -lt 2 ]; then
	echo -e "Usage:\ttypo <wrong-command> <right-command>"
	echo -e "\ttakes a typo and creates an alias using the"
	echo -e "\tprovided correct command"
    else
	#It goes typo wrong-command right-command
	argfirst="$1"
	# so $@ does not contain $1 anymore
	shift
        echo alias $argfirst=\'"$@"\' >> ~/.bashrc
        tail -n 1 ~/.bashrc
        . ~/.bashrc
    fi
}

Weil es nicht so definiert ist.
