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".
