shebang in shell scripts

A portable way to write shebang in zsh scripts is

#! /usr/bin/env zsh

The space between #! and /usr/bin/env is optional. But I like it since it is easy to see the interpreter that way.

Ref:

glob expansion in for loop

Do not use quotes if you want the expression to be expanded using wildcards. So the correct way is

    for fname in foo.????????
    do
        echo "$fname"
    done
    

The following will not expand the glob

    for fname in "foo.????????"
    do
        echo "$fname"
    done
    


Enclosing characters in double quotes preserves the literal value of all characters within the quotes, with the exception of $, `, \
