Instead of Changing History Characters
If you need to use !
(or your current history character) for a command (most often, a uucp or mail () command), you can type a backslash () before each history character. You can also drop into the Bourne shell quickly (assuming that you aren't on a system that has replaced the real Bourne shell with bash). Either of these are probably easier than changing histchars. For example:
%mail ora\!ishtar\!sally < file1
Quote the !s %sh
Start the Bourne shell $mail ora!ishtar!sally < file1
! not special here $exit
Quit the Bourne shell % And back to the C shell
The original Bourne shell doesn't have any kind of history substitution, so !
doesn't mean anything special; it's just a regular character.
