Answer 2

Answer:

Make a file executable in Terminal on Mac

Shell scripts must be executable files in order to run. You can use the chmod command to indicate that the text file is executable (that is, its contents can be run as a shell script).

In the Terminal app on your Mac, use the cd command to move into the directory that contains the file you want to make executable. For example:

% cd YourScriptDirectory

Enter the chmod command. For example:

% chmod 755 YourScriptName.sh

After making the shell script file executable, you can run it by entering its pathname. For example:

% ~/Documents/Dev/YourScriptName.sh

or

% cd ~/Documents/Dev/

% ./YourScriptName.sh
