## Running External Commands

The Options->Run a Command menu item permits any external command to be run directly from Understand for C++. Common commands to invoke are compilers, configuration management tools, and PERL/C programs written using Understand’s API.

While the command is executing, its output is shown in the Command Results Window if “Capture Output” is checked.

You can use the variables listed in Configuring Tools in the Command or the Parameter field.

Note that double clicking on a line of output that has a project filename in it (optionally with a line #) opens Understand’s editor to that file and line.

Tip: This works for most common output formats - if your command is generating a format we don’t cover please send it to our support email address.
