# OS Command

The OS Command tool allows you to enter operating system commands. Commands execute in the operating system context of the machine where the WebSpeed agent is running.

  NOTE:
  WebSpeed does not maintain context from one command to the next. Therefore, some commands (like changing your working directory, for example) do not execute. An error message states that the command generated no output.

The OS Command Tool contains the following interface elements:

Command Entry Field
  An input field for entering operating system commands.

Submit Button
  Executes the command displayed in the command entry field.

Load Script Button
  Displays scripts contained in the install_dir/src/web/scripts directory.

  You can create scriptes in any text editor but a script can contain only one line (no carriage returns). Filenames must have a .os extension.

  When you click on a script filename, its content appears in the command entry field. Choose the Submit button to execute.

Command Output Area
  Located below the command input field, it displays command output and error messages.
