Question

Suppose run_me.sh is a script file. Which command is used to make it executable?

(a) chmod +e run_me.sh

(b) chmod +a run_me.sh

(c) chmod +y run_me.sh

(d) chmod +x run_me.sh

I got this question in an internship interview.

This intriguing question comes from Interacting with MySQL topic in chapter General MySQL Use of MySQL

Answer 1

The correct choice is (d) chmod +x run_me.sh

For explanation: The command ‘chmod +x file_name’ makes a script file executable. mysql supports reading from a script file and executing queries from it. Before a script is run, it is necessary for it to be made executable.
