!!:s/ls/rm/

!! repeat previous command
s/ls/rm/ find "ls" in the pipe and replace it with "rm"

You can do this in any POSIX shell.

Take a look at the manpage for bash for a bit more explanation, the tcsh
manpage for a better one (IMHO).  Basically, if you know the number of the
line in the history buffer, you can use !<number> to get to it.  !
notation can get pretty deep really quickly.  There's !-<number> (go back
in the history number entries), !<pattern> (find the last command in the
history buffer matching command).
