How to write the history of commands entered via ssh in dd-wrt?

Question

linux

The wl500 router is flashed with dd-wrt (linux). When connecting via ssh, you have to enter long commands every time. I would like an analogue of history, so that the history of the entered commands is saved between connections. Is it real?

Answer 1

cat > /tmp/run.sh << EOF
