# Background color codes:
# 40=black 41=red 42=green 43=yellow 44=blue 45=magenta 46=cyan 47=white
RESET 0 # reset to "normal" color
DIR 01;34 # directory

FIFO 00;33 # pipe
SOCK 00;35 # socket
DOOR 00;35 # door
BLK 00;33 # block device driver
CHR 00;33 # character device driver
ORPHAN  00;31;40 # symlink to nonexistent file, or non-stat'able file ...
MISSING 01;30;40 # ... and the files they point to
SETUID 00;30;41 # file that is setuid (u+s)
SETGID 00;30;43 # file that is setgid (g+s)
CAPABILITY 00;30;41 # file with capability
STICKY 00;30;44 # dir with the sticky bit set (+t) and not other-writable
STICKY_OTHER_WRITABLE 00;30;46 # dir that is sticky and other-writable (+t,o+w)
OTHER_WRITABLE 00;30;42 # dir that is other-writable (o+w) and not sticky
