How do i run programs/scripts in linux command line?

Question

ok i have this script in my home directory, but permissions require it to be run as root. so i cd to my home directory and type in sudo scriptname but it says that its not a proper command or something

do i have to put a ./ or .\ or something (dot \)

Answer 1

Make sure that the script is executable with

chmod u+x scriptname

Then to execute:

/path/to/script/scriptname

Or, if you're already in that directory:

./scriptname

If you didn't start your script with the line

#!/bin/bash

then you will need to type:

/bin/bash ./scriptname
