2. Check the syntax of the command

  1. To start, type “cmd” in the search bar on your computer.
  2. If you are using Windows 10, click on the “Start” button, type “cmd”, and then press “Enter.”
  3. If you are using Windows 8 or 8.1, click on the “Windows key” on your computer keyboard, type “cmd”, and then press “Enter.”
  4. On a Mac, type ” Terminal ” in the search bar, and then press “Enter.”
  5. On a Linux or macOS computer, type “sudo bash” in the search bar, and then press “Enter.”

  6. When the Terminal window opens, type the following command to find out the error code that was returned when the command was executed:
    CMD
    If the error code is “127,” the syntax of the command is incorrect. The correct syntax for the command is “netstat -an”. The “netstat” command is used to view network connections and traffic.
    To correct the syntax of the command, type the following command in the Terminal window:
    netstat -an

3. Check the permissions of the command

  1. To check the permissions of the command, type the following command:

    The output of this command will list the permissions of the command. In this case, the ls -l command has the permissions of read and write.

  2. To fix the permissions of the command, type the following command:
    chmod u+x ls
    The output of this command will change the permissions of the ls command to the permissions of read and write.
