Changes a CLI variable

Views current CLI variables

Sets the default for a CLI variable

The dset command sets the value of CLI debugger variables. CLI and TotalView variables are described in Chapter 5, “TotalView Variables” .

If you use the dset command with no arguments, the CLI displays the names and current values for all CLI variables in the global namespace. If you use only one argument, the CLI returns and displays that variable’s value.

The second argument defines the value that replaces a variable’s previous value. You must enclose it in quotation marks if it contains more than one word.

If you do not use an argument, the CLI only displays variables in the current namespace. To show all variables in a namespace, enter the namespace name immediately followed by a double colon; for example, TV::.

You can use an asterisk (*) as a wildcard character to tell the CLI to match more than one string; for example, TV::g* matches all variables in the TV:: namespace beginning with g. For example, to view all variables in the TV:: namespace, enter the following:

When you press a default button within a File > Preferences dialog box, TotalView reinitializes some settings to their original values. However, what happens if you set a value in your tvdrc file when you press a default button? In this case, setting a variable doesn't change what TotalView thinks the default is, so it still changes the setting back to its defaults.

The next time you invoke TotalView, TotalView will again use the value in your tvdrc.

You can tell TotalView that the value set in your tvdrc file is the default if you use the -set_as_default option. Now when you press a default button, it will use your value instead of its own.

If your TotalView administrator sets up a global .tvdrc file, TotalView reads values from that file and merges them with your preferences and other settings. If the value in the .tvdrc file changes, TotalView ignores the change because it has already set a value in your local preferences file. If the administrator uses the -set_as_default option, you can be told to press the default button to get the changes. If, however, the administrator doesn't use this option, the only way to get changes is by deleting your preferences file.
