Executing a bash script in the terminal just by its name [duplicate]

Question

I am trying to follow this example in the Bash Guide over here where one can run a script just by its name instead of bash scriptname. First I used these three commands to create a bin directory, add its path to PATH, add that to the bash configuration file, and then reloading it:

$ mkdir -p "$HOME/bin"
$ echo 'PATH="$HOME/bin:$PATH"' >> "$HOME/.bashrc"
$ source "$HOME/.bashrc"

Then, I created a simple script that goes like this:

#!/usr/bin/env bash


echo "Hello World"

However, when I try to run it just by its name in the terminal, it gives me the error:

bash: /home/fieldsofgold/bin/mybashscript: Permission denied

Could anyone please help me with this? Thanks.

EDIT: Output for ls -l:

Answer 1

You will need to change the permissions. Notice the -rw-rw-r-- line in the line about mybashscript~. These characters show the permissions level for the file. Right now you have it so that nothing can execute the file, only read or write it.

An easy fix is chmod 775 ./mybashscript. This will change those characters to -rwxrwxr-x. The added x's mean that anyone can also execute the code, and will allow you to run your code.

If you are concerned that anyone can execute your code, which is a good thing if you are a security minded person or on a shared computer etc. You should look at this webpage that talks about what the different file permissions mean. Once you have a decent understanding of how permissions work you can edit them so that only certain users can read, write or run the file.

Answer 2

You don't seem to have executable permission for that script,

-rw-rw-r--  1 fieldsofgold fieldsofgold     0 Aug 11 15:10 mybashscript

type

sudo chmod a+x mybashscript

then run it with

./mybashscript

It'll run
