Sets the shell's default behavior to foreground execution mode.
setfg
Sets the shell's default execution mode to foreground. This forces the shell to wait for tasks to complete when they are executed. The shell will not accept new commands until the current task completes.
If the shell is currently in background mode and you wish to execute only a single program in foreground mode, you can append a '#' at the end of the command-line.
Use the showshellvars command to display the current execution mode.
Command implemented in shell V20.
Built-in shell command.
