How can I write a function in zsh
that invokes an existing command with the same name as the function itself? For example, I've tried this to illustrate my question:
function ls
{
ls -l $1 $2 $3
}
When I execute it with ls *
I get the following:
ls:1: maximum nested function level reached
I assume this is because the function is being called recursively. How I can avoid that?
This is a crude example, and in this case an alias would do the job, but I have a more complex example where an alias isn't suitable and so I would need to write a function.

What is happening is that you are recursively calling your
ls
function. In order to use the binary, you can use ZSH'scommand
builtin.
