## This script used to save the file list. of my home config. However this is
|
|
## quiet cumbersome to maintain, especially in sync with a VCS. Since VCS can do
|
|
## the same job much more easily, I do not feel the need anymore to use this
|
|
## script for backup purpose. Still it remains useful to create package lists
|
|
## for pacman, FreeBSD, TeX Live, and so on.
|
|
|
|
## Git can create a bundle with:
|
|
##
|
|
## git bundle create --all
|
|
##
|
|
## and can list files with:
|
|
##
|
|
## git ls-files
|
|
##
|
|
## Getting a .tar archive is still quiet easy with Git:
|
|
##
|
|
## tar cvJf archive.tar.xz $(cd $HOME && git ls-files)
|
|
|
|
## This script should be compatible with ksh, bash and zsh. Issue with sh
|
|
## however: we use arrays. Therefore we do not comply with POSIX and use some
|
|
## extended syntax for file input -- the <(...) syntax. We used to write the
|
|
## file list in an array which is not support by POSIX neither.
|
|
|
|
## Note for zsh: because of the Ksh-style arrays (index starting at 0), you
|
|
## cannot use array index to append elements to arrays -- otherwise the
|
|
## KSH_ARRAYS option for zsh must be used.
