I'm using a simple terminal command that adds a rule to iptables and it executes without problems:
sudo iptables -A OUTPUT -p tcp -m string --string "facebook.com" --algo kmp -j REJECT
When I run that command in a bash script, it returns sudo: ./script.sh: command not found
The script looks like this:
#!/bin/bash
sudo iptables -A OUTPUT -p tcp -m string --string "facebook.com" --algo kmp -j REJECT

If a script is not executable, one has to call it with an appropriate shell like /bin/sh or /bin/bash. This will ignore the shebang line and the script will be executed with the calling shell.
sudo /bin/sh ./script.sh
To run the script as inteded by OP you have to give the script execution rights.
chmod +x script.sh
sudo ./script.sh
In this case the script is executed with the shell of the shebang line.

I believe that you can also use. <scriptname>to run it in the currently running shell. That is how I executed scripts back in the day on my dialup Unix shell.
