The argument to a cmdtool(1) or a shelltool(1) window looks like it is supposed to be a command, but the system cannot find the command.
To run this command inside a cmdtool(1) or a shelltool(1), make sure the command is spelled correctly and is in your search path. If necessary, use a full path name. If you intended this argument as an option setting, use a minus sign (-) at the beginning of the option.
Both the cmdtool(1) and the shelltool(1) are OpenWindows terminal emulators.
