execute (program: STRING, arguments: TRAVERSABLE[STRING], keep_environment: BOOLEAN)
effective procedure
{ANY}
top
Execute the given program (how the program is discovered is OS-dependent), passing to it the arguments.
The environment is cleared if keep_environment is False.
require
  • program /= Void
  • is_ready
execute_command_line (command_line: STRING, keep_environment: BOOLEAN)
effective procedure
{ANY}
top
Execute the command_line through the operating system's basic shell.
The environment is cleared if keep_environment is False.
