Which part of it don't you understand?

As the manpage says, in a restricted shell you can't:

change directory

set the value of SHELL, ENV, or PATH

specify path or command names containing /


These restrictions apply after .profile (and $ENV, if specified) have
run. So you're restricted to those commands available in the $PATH as
specified in .profile and $ENV (and /etc/profile, of course).

You can't specify a command by absolute path so you can't run
/usr/local/bin/foo/secret-thing unless /usr/local/bin/foo is in your PATH

You can't change your PATH (so you can't go

PATH=$PATH:/usr/local/bin/foo
secret-thing

And you can't cd, so (assuming the current directory is in the PATH,
which is probably a Very Bad Idea anyway), you can't

cd /usr/local/bin/foo
secret-thing
