suppose I want to enter a multiline command via bash I know that I can append \ in the end of the line to enter a new line
however is it possible to enter a legitimate "text editor mode" where you don't even have to enter \ and simply press enter would suffice
eg..you type in the command into the command line then before entering the parameters you press some magic button which allows you to enter a vi like mode then you enter stuff into the "vi mode" then you exit and then the text you entered in the "vi mode" turns into the parameters of the command then you press enter then the command executes
is it possible to do that in bash command line? if so, how do I do it?
See man bash
:
edit-and-execute-command (C-xC-e)
Invoke an editor on the current command line, and execute the
result as shell commands. Bash attempts to invoke $VISUAL,
$EDITOR, and emacs as the editor, in that order.
Per default bash is configured for emacs mode, hence the emacs like C-xC-e command.
If you really like vi you can also set your bash into vi mode: set -o vi
. This allows you to do normal line editing the vi way without invoking an explicit editor.
Bash can emulate vim mode (though not very well) with:
set -o vi
