FIFO ;33 # pipe
SOCK ;35 # socket
DOOR ;35 # door
BLK ;33;01 # block device driver
CHR ;33;01 # character device driver

# List any file extensions like '.gz' or '.tar' that you would like ls
# to colorize below. Put the extension, a space, and the color init string.
# (and any comments you want to add after a '#')

#.cmd ;32 # executables (bright green)
#.exe ;
#.com ;
#.btm ;
