You original wrote ps f but now the question reads ps --forest. The two are not the same...
$ ps f
PID TTY STAT TIME COMMAND
27614 pts/1 Ss 0:00 -ksh
27656 pts/1 R+ 0:00 _ ps f
3356 pts/0 Ss 0:00 -ksh

$ ps --forest
PID TTY TIME CMD
27614 pts/1 00:00:00 ksh
27658 pts/1 00:00:00 _ ps
They contain the same scope as ps g and ps
