A random-file-reading programme for use with the phosphor(6) xscreensaver.
Dump available fonts that match a pattern:
xlsfonts -fn '*iso10646*' >/tmp/iso10646.txt
Test the programme (/usr/local/bin/rand_file.awk) with a selected font:
/usr/lib/xscreensaver/phosphor `xwininfo -root | grep -- -geom` \ -scale 2 -font -misc-fixed-medium-r-normal--14-130-75-75-c-70-iso10646-1 \ -delay 32768 -ticks 4 -program \ '/usr/local/bin/rand_file.awk $(find /usr/include -type f -iname \*.h)'
Use the following command in the Settings... -> Advanced -> Command Line
field of xscreensaver-demo for the Phosphor mode:
phosphor -root -delay 32768 -ticks 4 -scale 2 -font -misc-fixed-medium-r-normal--14-130-75-75-c-70-iso10646-1 -program '/usr/local/bin/rand_file.awk $(find /usr/include -type f -iname \*.h)'
