In Ch04, permission denied when executing my script

[lobaluna]

Hi, I have assigned permissions to execute to all, but still my script (named differently, not 'top-words-n.sh') cannot run. First I assigned execute permission to user only, but it didn't work neither :(

Since we are in the zsh shell, it returns an error:

$ ./palabras-comunes.sh        
zsh: permission denied: ./palabras-comunes.sh

However, if I use:

$ zsh ./palabras-comunes.sh

…the script is executed.

The same happens to the last code example in section 4.2.4.
Please update the wording of the text in the chapter, accordingly.
