# Portability notes:
|
|
# To guarantee this script works on all platforms that support fluxbox
|
|
# please keep the following restrictions in mind:
|
|
#
|
|
# - don't use if ! command;, use command; if [ $? -ne 0 ];
|
|
# - don't use [ -e file ] use [ -r file ]
|
|
# - don't use $(), use ``
|
|
# - don't use ~, use ${HOME}
|
|
# - don't use id -u, use whoami
|
|
# - getopts won't work on all platforms, but the config-file can
|
|
# compensate for that.
|
|
# - various software like grep/sed/perl may be not present or not
|
|
# the version you have. for example grep '\W' only works on gnu-grep.
|
|
# Keep this in mind, use bare basic defaults.
|
|
# - Do _NOT_ suggest to use #!/bin/bash. Not everybody uses bash.
|
|
# Non portable features like getopts in this script can be achieved in
|
|
# other ways.

1) To replace all occurrences of bsetbg with fbsetbg in a file use this
|
|
command:
|
|
|
|
perl -pi -e 's,([^f]|^)bsetbg,fbsetbg,' filename
|
|
|
|
2) If you want the style to set the wallpaper and you want fbsetbg to
|
|
remember the previous wallpaper put this in your ~/.fluxbox/init
|
|
|
|
session.screen0.rootCommand: fbsetbg -l
|
|
|
|
3) Use fbsetbg -d to find out what wallpapersetter fbsetbg will use and
|
|
what he thinks about it.
