man bash (or csh, or any other shell):
History expansion is performed immediately after a complete line is read,
before the shell breaks it into words. It takes place in two parts. The
first is to determine which line from the history list to use during sub
stitution. The second is to select portions of that line for inclusion
into the current one. The line selected from the history is the event,
and the portions of that line that are acted upon are words. Various mod
ifiers are available to manipulate the selected words. The line is broken
into words in the same fashion as when reading input, so that several
metacharacter-separated words surrounded by quotes are considered one
word. History expansions are introduced by the appearance of the history
expansion character, which is ! by default. Only backslash (\) and single
quotes can quote the history expansion character.
! Start a history substitution, except when followed by a blank, new
line, = or (.
!n Refer to command line n.
!-n Refer to the current command line minus n.
!! Refer to the previous command. This is a synonym for `!-1'.
!string
Refer to the most recent command starting with string.
!?string[?]
Refer to the most recent command containing string. The trailing ?
may be omitted if string is followed immediately by a newline.
^string1^string2^
Quick substitution. Repeat the last command, replacing string1
with string2. Equivalent to ``!!:s/string1/string2/'' (see Modi
fiers below).
!# The entire command line typed so far.
Looks like it's working as expected. ;)
