Running a shell script

You can execute a shell script in these ways:

• Invoke another shell with the name of your shell script as an argument:

  sh myscript
    

• Load your script as a “dot file” into the current shell:

  . myscript
    

• Use chmod to make the shell script executable, and then invoke it, like this:

  chmod 744 myscript
  ./myscript
    

  In this instance, your shell automatically invokes a new shell to execute the shell script.
