The ACL technology is more advanced than traditional UNIX-style permissions because it allows for an arbitrary number of userĪnd group permissions rules per item.

Once again, the ls command is your primary tool for viewing file and folder information in the command line.

If you are using the readline bindings through use readline-bindings, you should bind this function to the Ctrl-L key to keep the correct markers when clearing the screen.If you aren’t already comfortable with navigation in the UNIX command line, then it’s strongly recommended that you study The iterm2:clear-screen function clears the screen and issues the corresponding markers before redrawing the prompt. The escape sequences used by iTerm2 for shell integration are described in detail in the Proprietary Escape Codes documentation. Note: This file is written in literate programming style, to make it easy to explain. You should for the most part not need to use these functions directly, as they are inserted in the correct places by the iterm2:init function. The FTCS codes used for shell integration cal also be emitted manually if needed, using the iterm2:ftcs-prompt, iterm2:ftcs-command-start, iterm2:ftcs-command-executed and iterm2:ftcs-command-finished functions. See the Implementation section below for the full list of available functions. Most of the iTerm2 custom escape codes are implemented by this module, either through custom functions or by constructing them directly using the iterm2:escape-cmd, iterm2:cmd or iterm2:set functions.
