Where do I put a function in zsh?
There is (once again) a bit of configuration required to get this working. Instead of declaring the function directly the configuration file, you can put the function in a separate file. zsh has a built-in variable called fpath which is an array of paths where zsh will look for files defining a function.
How do I keep functions / variables local to my zshrc?
Any variable that I declare in my zshrc is available in the shell as an environment variable. I don’t want this to happen. I tried putting the variables in a function and setting them as local, but then the function is available outside of the zshrc. How can I make it so what happens in my zshrc stays in my zshrc?
Can you use aliases and functions in zsh?
As with aliases, functions in your zsh configuration will work just as they did in bash. This code in your zsh configuration file will define the vnc function and make it available in the shell. However, zsh has some features which make using functions more flexible. There is (once again) a bit of configuration required to get this working.
What to do if the word local is not appended to a variable?
If you do not append the word local to a variable it will remain until you do one of the following: Open a new terminal window. Run exec zsh or exec bash depending on your shell. This just clears out your local variables that were not assigned with the word local.
Where are the zsh files located on a Mac?
Looking at the ZSH documentation on Startup/Shutdown Files, there are a number of files (located in the home directory $HOME or ~/ ): What is also confusing is that ~/.zprofile and ~/.zlogin are both for login shells, so, things can get confusing as to what to put where.
What’s the difference between Bash and zsh scripts?
The most significant difference, which will affect most scripts is how zsh treats word splitting in variable substitutions. In bash substituted variables are split on whitespace when the substitution is not quoted. To demonstrate, we will use a function that counts the number of arguments passed into it.
Do you have to switch scripts from Bash to zsh?
Once you have split text into an array, remember, that in zsh array indices start at 1: Switching your scripts from bash to zsh requires a bit more work than merely switching out the shebang. However, since /bin/bash will still be present in Catalina, you do not have to move all scripts immediately.
What makes zsh better than other scripting languages?
zsh will not split a variable when substituted. With zsh the contents of a variable will be kept in one piece: The positive effect of this is that you do not have to worry about quoting variables all the time, making zsh less error prone, and much more like other scripting and programming languages.
