Would it make sense to remove references to Yaourt and include a more generic solution for installing packages from the AUR?

Or would it be better to add different sections for different AUR helpers? ("If you use Yaourt...", "If you use Packer...", "If you use aurget...") - drcouzelis, 12 March 2010

I prefer to simply write "Install X from the AUR." -- pointone 23:54, 12 March 2010 (EST)
I prefer this too, but still I think that most users are favorable to Yaourt. It is the best tool for those new to Arch and by far the most complete. This will probably change sometime in the ?near? future but until then I think giving the reader the most prevalent option is the wisest solution. Hummm, maybe I'm old fashioned :).

Backup Script

[Restoring here the script deleted with without an appropriate discussion. -- Kynikos (talk) 14:59, 12 April 2013 (UTC)]

This backup script has the ability to add to the include and exclude files and the ability to backup the configurations. The usage is:

 bckcfg <i|e|n|c> - backup configurations
  i - add to the include list a file or folder
  e - add to the exclude list a file or folder or regexp pattern
  n - add note
  c - create backup

For example to add to the include file:

bckcfg i /etc/rc.conf

And to add to the exclude file:

bckcfg e .thumbnails/

The script is able to detect the full path so writing a relative or partial path is acceptable.

To backup, this script names your backup by several definable variables, removes old backups if desired, then backs up the configurations. The include and exclude files are placed in the same directory as the backup script.

# Backup configurations

# Backup destination directory

# Backup name
comp="${HOSTNAME}"  # Computer name
dist="arch"         # Distro
date="$(date "+%F")"

# Include and exclude file locations

scrp_help () {
echo " ${0##*/} <i|e|n|c> - backup configurations
  i - add to the include list a file or folder
  e - add to the exclude list a file or folder or regexp pattern
  n - add note
  c - create backup"

del_old_bckps () {
if [[ -n "$(find "$bckp_dest" -mtime +30)" ]]; then
  find "$bckp_dest" -name "$distro-$type-*" -mtime +30 -exec rm {} \
  \; && echo " Deleted backups older than one month."
