# style
# Set status line message command style, where style is a comma-separated list
# of characteristics to be specified.
#
# These may be ‘bg=colour’ to set the background colour, ‘fg=colour’ to set the
# foreground colour, and a list of attributes as specified below.
#
# The colour is one of: black, red, green, yellow, blue, magenta, cyan, white,
# aixterm bright variants (if supported: brightred, brightgreen, and so on),
# colour0 to colour255 from the 256-colour set, default, or a hexadecimal RGB
# string such as ‘#ffffff’, which chooses the closest match from the default
#
#
#
#
#
#
# string
#
# Display string (by default the session name) to the left of the status line.
# string will be passed through strftime(3) and formats (see FORMATS) will be
# expanded.  It may also contain the special character sequence #[] to change
# the colour or attributes, for example ‘#[fg=red,bright]’ to set a bright red
# foreground.  See the message-command-style option for a description of colours
# and attributes.
#
# For details on how the names and titles can be set see the NAMES AND TITLES
# section.
#
# Examples are:
#
#       #(sysctl vm.loadavg)
#       #[fg=yellow,bold]#(apm -l)%%#[default] [#S]
#
# The default is ‘[#S] ’.
#
#
#
# %if #{==:#{host},myhost}
#   set -g status-style bg=red

#
#
