# /etc/rc.status
# vim: syntax=sh
# Definition of boot script return messages
#
# The bootscripts should use the variables rc_done and rc_failed to
# report whether they failed or succeeded. See /etc/init.d/skeleton for
# an example how the shell functions rc_status and rc_reset are used.
#
# These functions make use of the variables rc_done and rc_failed;
# rc_done_up and rc_failed_up are the same as rc_done and rc_failed
# but contain a terminal code to move up one line before the output
# of the actual string. (This is particularly useful when the script
# starts a daemon which produces user output with a newline character)
#
# The variable rc_reset is used by the master resource control script
# /etc/init.d/rc to turn off all attributes and switch to the standard
# character set.
#
# \033 ascii ESCape
# \033[<NUM>G move to column <NUM> (linux console, xterm, not vt100)
# \033[<NUM>C move <NUM> columns forward but only upto last column
# \033[<NUM>D move <NUM> columns backward but only upto first column
# \033[<NUM>A move <NUM> rows up
# \033[<NUM>B move <NUM> rows down
# \033[1m switch on bold
# \033[31m switch on red
# \033[32m switch on green
# \033[33m switch on yellow
# \033[m switch off color/bold
# \017 exit alternate mode (xterm, vt100, linux console)
# \033[10m exit alternate mode (linux console)
# \015 carriage return (without newline)
