How to define and load your own shell function in zsh?
Zsh has two modes of autoloading files: Zsh’s native way and another mode that resembles ksh’s autoloading. The latter is active if the KSH_AUTOLOAD option is set. Zsh’s native mode is the default and I will not discuss the other way here (see “man zshmisc” and “man zshoptions” for details about ksh-style autoloading).
When to use funcname instead of func name in Bash?
When bash arrays are accessed without an index the first element of the array will be returned, so $FUNCNAME will work in simple cases to provide the name of the immediately current function, but it also contains all other functions in the call stack.
How to find the name of a function in Bash?
An array variable containing the names of all shell functions currently in the execution call stack. The element with index 0 is the name of any currently-executing shell function. The bottom-most element (the one with the highest index) is “main”. This variable exists only when a shell function is executing.
How to determine the path to a shell script?
The element with index 0 is the name of any currently-executing shell function. The bottom-most element (the one with the highest index) is “main”. This variable exists only when a shell function is executing. Assignments to FUNCNAME have no effect and return an error status.
What should / shouldn’t go in the zsh file?
You set options for the interactive shell there with the setopt and unsetopt commands. You can also load shell modules, set your history options, change your prompt, set up zle and completion, et cetera. You also set any variables that are only used in the interactive shell (e.g. $LS_COLORS ).
What should / shouldn’t go in.zshenv,.zlogin?
Here is a non-exclusive list of what each file tends to contain: Since .zshenv is always sourced, it often contains exported variables that should be available to other programs. .zshrc is for interactive shell configuration. .zlogin is sourced on the start of a login shell.
Which is an example of a zsh instance?
PATH (or its associated counterpart path) is a good example because you probably don’t want to restart your whole session to make it update. By setting it in that file, reopening a terminal emulator will start a new Zsh instance with the PATH value updated.
What are the arguments of a shell function?
Runs an executable program and returns a Variant ( Double) representing the program’s task ID if successful, otherwise it returns zero. The Shell function syntax has these arguments:
Why does the shell function run asynchronously?
Note: By default, the Shell function runs other programs asynchronously. This means that a program started with Shell might not finish executing before the statements following the Shell function are executed. Note: Examples that follow demonstrate the use of this function in a Visual Basic for Applications (VBA) module.
What is the task ID of the shell function?
The task ID is a unique number that identifies the running program. If the Shell function can’t start the named program, an error occurs. On the Macintosh, vbNormalFocus, vbMinimizedFocus, and vbMaximizedFocus all place the application in the foreground; vbHide, vbNoFocus, vbMinimizeFocus all place the application in the background.
