Once you get accustomed to these, they can be very useful for quickly performing certain commands without moving your hands from the "home" keyboard position.If you're an Emacs user or if you have experience with Linux-style shells, the following will be very familiar.We'll group these shortcuts into a few categories: navigation shortcuts, text entry shortcuts, command history shortcuts, and miscellaneous shortcuts.
[Howto] key bindings in shells
Julia comes with a full-featured interactive command-line REPL (read-eval-print loop) built into the julia executable. In addition to allowing quick and easy evaluation of Julia statements, it has a searchable history, tab-completion, many helpful keybindings, and dedicated help and shell modes. The REPL can be started by simply calling julia with no arguments or double-clicking on the executable:
The Julia REPL makes great use of key bindings. Several control-key bindings were already introduced above (^D to exit, ^R and ^S for searching), but there are many more. In addition to the control-key, there are also meta-key bindings. These vary more by platform, but most terminals default to using alt- or option- held down with a key to send the meta-key (or can be configured to do so), or pressing Esc and then the key.
Julia's REPL keybindings may be fully customized to a user's preferences by passing a dictionary to REPL.setup_interface. The keys of this dictionary may be characters or strings. The key '*' refers to the default action. Control plus character x bindings are indicated with "^x". Meta plus x can be written "\\M-x" or "\ex", and Control plus x can be written "\\C-x" or "^x". The values of the custom keymap must be nothing (indicating that the input should be ignored) or functions that accept the signature (PromptState, AbstractREPL, Char). The REPL.setup_interface function must be called before the REPL is initialized, by registering the operation with atreplinit . For example, to bind the up and down arrow keys to move through history without prefix search, one could put the following code in /.julia/config/startup.jl:
If you have a set of key bindings that you like to use all the time,you can specify them in your initialization file by writing Lisp code.See The Emacs Initialization File, for a description of the initialization file.
In this article we are going to see how to use socat in an imaginary scenario of attacker and victim, where we are trying to get a shell to the victim`s machine. We are going to see both bind and reverse shells and also the difference between encrypted and not encrypted traffic. The described methods apply for both Linux and Windows.
In this article we saw how to create bind and reverse shells using socat and how to take advantage one of the many features socat offers, the openssl. We presented the commands required to create the two kinds of shells along with how to make your own .pem file to encrypt your traffic.
To make it permanent, just add it to .bash_profile or a similar script that is ran by login shells. Just don't do it for non-login shells .bashrc because from my experience these dconf and gsettings slow it down significantly. Changing/Adding 30 bindings takes a second ! You don't want this in non-login shell (.bashrc)!
Here is a Python script which uses PyGObject bindings instead of calling gsettings and parsing the output. When a keybinding of the same name already exists, it replaces it instead of adding a duplicate.
These keybindings can be changed using PSReadLine cmdlets or the application that's hostingPowerShell. Keybindings can be different on non-Windows platforms. For more information, seeabout_PSReadLine_Functions.
Open a configuration dialog and change preferences for the following:fonts, indentation, keybindings, text color themes, startup windows andsize, additional help sources, and extensions. On macOS, open theconfiguration dialog by selecting Preferences in the applicationmenu. For more details, seeSetting preferences under Help and preferences.
We need our additional keybindings to load after the shell is initialized, so wedefine a function that contains all of the custom keybindings and decorate itwith the appropriate event, in this case on_ptk_create.
The best way to get a sense of what this code is trying to do is byusing it. Basically, the philosophy represents a blend between theease of use of modern day shells, and the review-before-you-proceedmentality of Plan 9's 9term.
I'm trying to learn to use emacs with its key bindings, but since I usually work on a mac pro I'm asking if is it possible bind ctrl+option for meta key instead of command and pass command to system or bind command in CUA style for movement, copying and pasting. It is not very important to do it, because I'm trying to use emacs original keys and I find they very simple to remind. Just asking if is it possible. As I've seen the combination ctrl+option is used for symbols, but I've already custom system bindings for symbols based on option key or shift+option key combination. Since I'm using emacs just for write C and Python programs I don't need a vast set of symbols.
* The structure of a keymap is an advanced topic (not for this overview), and that is what you see if you try to use, say, `C-h v' on a keymap variable. `C-h b' and `C-h m' can sometimes help by providing a user-readable list of bindings, but they don't help with keymaps that are hard to get at except via their variables (e.g., minibuffer keymaps).
I thought that level 5 was for defining major mode keybindings that override minor mode keybindings that may be present, i.e. it "takes back" any minor mode keybindings that the major mode cannot afford to lose.
For example, you can configure bindings to jump to specific windows,you can set specific applications to start on specific workspaces, you canautomatically start applications, you can change the colors of i3, and youcan bind your keys to do useful things.
Conceptually, included files can only add to the configuration, not undo theeffects of already-processed configuration. For example, you can only add newkey bindings, not overwrite or remove existing key bindings. This means:
A keyboard binding makes i3 execute a command (see below) upon pressing aspecific key. i3 allows you to bind either on keycodes or on keysyms (you canalso mix your bindings, though i3 will not protect you from overlapping ones).
A mouse binding makes i3 execute a command upon pressing a specific mousebutton in the scope of the clicked container (see [command_criteria]). Youcan configure mouse bindings in a similar way to key bindings.
You can have multiple sets of bindings by using different binding modes. Whenyou switch to another binding mode, all bindings from the current mode arereleased and only the bindings defined in the new mode are valid for as long asyou stay in that binding mode. The only predefined binding mode is default,which is the mode i3 starts out with and to which all bindings not defined in aspecific binding mode belong.
Working with binding modes consists of two parts: defining a binding mode andswitching to it. For these purposes, there are one config directive and onecommand, both of which are called mode. The directive is used to define thebindings belonging to a certain binding mode, while the command will switch tothe specified mode.
As you learned in the section about keyboard bindings, you will haveto configure lots of bindings containing modifier keys. If you want to saveyourself some typing and be able to change the modifier you use later,variables can be handy.
For key bindings in the prefix table the -r option can be used to make them repeatable.For example with tmux bind -r t new-window Ctrl + b t is needed to open a first new window, then you cankeep hitting t to open more without having to hit Ctrl + b each time. The repeat-time setting decides how much timeyou have to repeat the key before the prefix times out (default: 500 milliseconds).
Remember directory access history? This plugin improves navigation through your directories even further. It adds keyboard bindings to allow you navigate through the directory history even easier. Start by adding dirhisotry to the configuration file:
After you had installed Oh My Zsh a startup configuration file .zshrc was created in your home directory. It is a shell startup file where you put your commands, aliases, functions, options, and key bindings. This file is loaded automatically when you initiate a new terminal session.
If you are an avid Vim user, enable Vim key bindings. This will put you in the insert mode by default when you open your terminal. Hit ESC button to enter the command mode instead. You may enable Vim key bindings with the following line:
Type it into your prompt (and add it to your .zshrc file) and emacs bindings are going bye-bye. Escape will bring you to normal-mode, while i, a, o etc. will bring you back to insert-mode, just as with your favorite editor. Use j and k in normal-mode to go through your history and move around within the line with h, l, w, b and the like.
You can take a look at the key bindings defined for emacs-mode by typing bindkey -M emacs -L and reuse the bindings you like. See the zshzle manpage for more pre-defined widgets for which you could define bindings.
This bit of configuration works by adding conditional logic to the [CODE]ctrl-[/CODE] key bindings. When one of these movement commands is used, it checks if the current tmux pane is running vim. If so, the appropriate vim split navigation command is sent. Otherwise, the appropriate tmux pane navigation command is sent.
Shell Game beggars can sometimes be found in the Arcade; they also have a small chance to spawn elsewhere. After giving the beggar a coin by bumping into them, they will lift a skull, revealing a Penny, Bomb, Red Heart, or Key. The beggar will shuffle the skulls around and wait for Isaac to bump into 1 of the 3 shells. In return, the beggar will spawn either 2 of the pickups or an Attack Fly. 2ff7e9595c
