# /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[<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
