The entirety of my Openbox autostart file is as follows:

# Compositor
picom &

# Korean input
ibus-daemon -dr &

# Screensaver
xscreensaver -no-splash &

# Wallpaper
while true; do
    nitrogen --random --set-auto
    sleep 3600
end

But when I login, it appears as though only picom was run successfully.

Running bash ~/.config/openbox/autostart from a terminal indicates

/home/max/.config/openbox/autostart: line 33: syntax error: unexpected end of file

so I think something is wrong with my while loop, but what?

In bash like in the Bourne shell where that syntax initially comes from, while loops end with done:

# Wallpaper
while true; do
    nitrogen --random --set-auto
    sleep 3600
done

What's happening is that the shell is finding the start of the while loop and then reads ahead, searching for its end. It reaches the end of the file before finding the terminating done keyword and complains. Hence "unexpected end of file".

  • @Max There is no such custom, but it's perfectly fine to accept one answer first and then change one's mind and accept another.

  • FWIW and for completeness, end is used to terminate while loops in csh, tcsh and fish. zsh has short forms that don't require the do and done, reminiscent of rc's while (cond) cmd's ones. Jun 1 at 6:59
