#!bash Coloured prompts.
-# To use, add a call to __ps1 in your .bash_profile file.
+# profile-required: TERM.bashrc
#
# The prompt comprises multiple parts, some of which may be hidden by unsetting
# shell variables or using the ``prompt'' function.
# green if the last command exited 0 or in red otherwise.
# This part will be shown only if __ps1_user is 1. By default it is 1.
# The success and failure colours can be changed by modifying
-# $PROMPT_OK_COLOUR and $PROMPT_FAILURE_COLOUR respectively.
+# $PROMPT_OK_COLOUR and $PROMPT_FAILED_COLOUR respectively.
#
# The second part of the prompt is taken from git-completion.bashrc.
# It is shown only if __ps1_git is 1. By default it is 0.
# The fifth part of the prompt is the exit status of the last command.
# This part will be shown only if __ps1_user is set and the exit status is
# non-zero.
-#
+#
+# The sixth part of the prompt is the number of background jobs managed
+# by the shell, in square brackets. If all background jobs are running,
+# their number will be shown as [n]. If some are stopped, the number of
+# running (r) and total (t) jobs will be shown as [r/t].
+# This part will be shown only if __ps1_bg is 1. By default it is 0.
+
# The final part of the prompt is the (full) working directory and $ string.
+# If the shell is running as root the # string's colour can be changed by
+# modifying $ROOT_OK_COLOUR and $ROOT_FAILED_COLOUR.
#
# Colouring is performed by the __ps1_col() and __ps1_ret() functions.
# We redirect stderr to /dev/null when calling these functions to prevent
# SVN: magenta.
