Here is a list of commands for Linux that will be useful to navigate Recalbox via a terminal.
dir. It lists the contents of a folder. You can see the options available on this page.cd. It allows you to change the directory (cd = Change Directory). You can consult the available options on this page.copy. It allows you to copy files or directories. You can consult the available options on this page.move or ren.

You can see the available options on this page.To check the processor (CPU) temperature, run the following command:
cat /sys/class/thermal/thermal_zone0/temp
Then divide the result by 1000 to get the temperature in Celsius.
# cat /sys/class/thermal/thermal_zone0/temp
54530
To check the applied overclocking values, run the following command:
cat /boot/recalbox-oc-config.txt
You will get a result similar to this example:
# Plateform: RPI4
# Description: Extrem
# Warning
# Frequency: 2000
over_voltage=6
arm_freq=2000
gpu_freq=750
If you experience crashes / lockups with the Mupen64 standalone N64 emulator, due to compatibility issues with the roms, you can easily "kill" the emulator instead of rebooting the Raspberry. To do this, you need to identify the Mupen64 process ID with the following command:
ps aux | grep mupen64
You should get a list similar to :
26193 root mupen64plus --corelib /usr/lib/libmupen64plus.so.2 .0.0 --gfx /usr/lib/mupen64plus/mupen64plus-video-gliden64.so --configdir /recalbox/share/system/configs/mupen64/ --datadir /recalbox/share/system/configs/mupen64/ /recalbox/share/roms/n64/007 - GoldenEye (Europe).n64
26196 root grep mupen64
In this case, the process ID of the Mupen64 process (PID) is 26193. You can now kill the Mupen64 process with the following command:
kill -1 <your_PID>
So for our example: kill -1 26193
Once the process is killed, you will automatically return to EmulationStation.
To update the roms list for example or to update the images of newly scraped games from your PC, you will need to stop and restart EmulationStation:
