daptup

DAPTUP(8)						      System Manager's Manual							 DAPTUP(8)

NAME

       daptup - wrapper script on 'apt-get update'

SYNOPSIS

       daptup [ --pre | --post | --last ] [ -h | --help ] [ --nocolor ]

OPTIONS

       --pre  Do only 'pre' stage: collect info that will be used as 'old'. Usually need to be specified only in apt hooks.

       --post If  appropriate option is enabled in config file, do only 'post' stage: collect 'new' info and output changes. Otherwise do nothing.
	      Usually need to be specified only in apt hooks.

       --last Output changes only. This option is supposed to be specified when you want to see changes made in the last update. Note that list of
	      outdated packages, if daptup is configured to output it, will be rebuilt.

       -h --help
	      prints the help

       --nocolor
	      Disables	color  output, useful for scripts or when output is not terminal. Now works only with --last option, however, you can dis-
	      able color globally in configuration file.

       daptup is a script that runs "apt-get update" inside and outputs list of packages recently entered to repo, list of packages which got  new
       updates, list of changes in 'watched' packages and, optionally, list of outdated packages.

       Starting with 0.8.0 version, daptup uses apt hooks and you don't need to explicitly call it if you use 'apt-get update'.

TROUBLESHOOTING

       If  daptup was interrupted while building the lists, the cached lists can stay in inconsistent state, which is inappropriate if you want to
       use --last option before the new update. There is nothing to do if interrupt was occured  at  the  moment  when	old  lists  were  building
       (besides  running  the  new  update). However, if interrupt was occured when the new lists were building, you can easily redo this stage by
       calling 'daptup --post'.

FILES

       /etc/daptup.conf
	      self-documented configuration file

       /var/spool/daptup/outdated
	      cached file with info about outdated packages
