![]() ( GNU Bash Reference Manual, 1.2 What is a Shell?)ģ When executing non-interactively, shells execute commands read from a file. These shells are typically interactive shells.Ģ In interactive mode, they accept input typed from the keyboard. zlogoutġ A login shell is simply a shell, whether local or remote, that allows a user to authenticate to the system. ![]() etc/zshenv) then from the file in your home directory ( ~/.zshenv) as it goes through the following order. Keep in mind that it reads first from the system-wide file (i.e. That one plist will contain everything you need to set up iTerm2 like you want. This is the order in which these files get read. Another option is to configure iTerm2 like you want, complete with profile themes, then back up the /Library/Preferences/ file into your dotfiles. SSH sessions are login and interactive so they'll behave just like your initial Terminal session and read both. Then open another shell (type zsh) that variable won't be accessible anymore. zprofile, then opening Terminal and seeing if that variable/alias exists. You can test this out by putting an alias or setting a variable in. However, any subsequent shells that are opened are only interactive. Specifically, Terminal initially opens both a login and interactive shell even though you don't authenticate (enter login credentials). zprofile, on Unix/Linux.Īpple does things a little differently so it's best to be aware of this. Personally, I don't use this one because I set the PATH variable in my script itself to ensure portability.īut very useful! This is read when you log out of a session and is very good for cleaning things up when you leave (like resetting the Terminal Window Title)įor an excellent, in-depth explanation of what these files do, see What should/shouldn't go in. Those run under a non-interactive shell 3 so anything in. I say this is optional because is geared more toward advanced users where having your $PATH, $PAGER, or $EDITOR variables may be important for things like scripts that get called by launchd. This is where you set environment variables. ![]() It's typically a place where you "set it and forget it" type of parameters like $PATH, $PROMPT, aliases, and functions you would like to have in both login and interactive shells. This sets the environment for interactive shells 2. Since Bash was the default shell for everything up to Mojave, stick with. zprofile are basically the same thing - they set the environment for login shells 1 they just get loaded at different times (see below).zprofile is based on the Bash's. I posted a more narrowly scoped question on Unix & Linux and got some clarification on how these files "work." Here's the summary of that answer and what I've learned in my research as to what, in my opinion should be used in a ZSH environment on a Mac. This shortcut can be used to open a new window or tab. This serves as the default session name for sessions created with this profile, which is an interpolated string. This is an attempt to write a canonical QA for this issue, as per the Meta post: Where is the list of canonical questions stored for Ask Different? I expect it to be periodically edited with the goal of becoming a comprehensive information resource. Gives the name of the profile which is shown in menus, preferences, and the profiles window.
