It's a '!' in a quoted string. Another example of posix braindeath -- how long before people realize that the thing branded 'posix' now isn't the real posix that was started to *describe* behaviors, not prescribe or proscribe behaviors. They just bought the name -- like PacBell swallowed SW Bell and then bought the AT&T name (not the labs... just the name). So that AT&T today is really the old PacBell in new shoes... It's like its really tweaky watching a first run anime from Japan (in japanese) with a Universal logo on it... and words that it is an NBC company. (Who is now owned by Comcast). Oh well when I role my own, I think I usually leave histexpand out of it. Having to remember line numbers seems ridiculous... and I can search by hitting ESC /string (in vi mode anyway). -l
