- ! --- shell escape
-
- default range syntax
- 1,$ ![<Unix command>]
-
- The user's choice of shell is taken from the $SHELL environment vari-
- able and used to execute <Unix command> if it is present. Otherwise,
- an interactive shell is created. A leading ! is replaced by the pre-
- vious shell command. Thus !! executes the previous command. An
- unescaped % is replaced by the saved file name. An expanded shell
- command is echoed before it is executed. After an interactive shell
- exits, the screen is immediately redrawn. If a command was run, the
- results are left on the screen, and the user must type a return to
- redraw the editing window.
-
- To return to the command directory, type "hcomdir".
