I was writing a small bash script the other day when I wanted to test it.
I went to try to execute the script and received a permission denied error:
$ ./setup.sh zsh: permission denied: ./setup.sh
Looking at permissions, I could see that there were not execution rights for the file:
$ ls -la -rw-r--r-- 1 stephen staff 671B Nov 19 13:28 setup.sh
It turns out that’s not a default right for a file. To fix that, you can change the file’s permissions with CHMOD1:
$ chmod +x setup.sh $ ls -la -rwxr-xr-x 1 stephen staff 671B Nov 19 13:28 setup.sh
-xflag only, there are other flags. The flags are: user (
u), group (
g), other (
o), and all (
a). For example, to change the execution rights for only users, you could do:
$ chmod u+x setup.sh
