Wajig Overview


Wajig is designed to run in such a way as to suit the system it is running on and the policies of the system administrators. It can be run as a normal user, but once a privileged command is required it will use either su and ask for the root user's password, or else it can use sudo and rely on the normal user's password. It can also be run directly as root without any extra setup (i.e., without the need for sudo or regularly supplying passwords). Using sudo requires a little setting up as described below in Section 6.5.

Try the help command for a list of common commands provided by wajig:

  $ wajig help

Examples commands include:

  $ wajig update               (= dselect update)
  $ wajig install less         (= apt-get install less)
  $ wajig new                  (list new packages since last update)
  $ wajig newupgrades          (list packages upgraded since last update)
  $ wajig toupgrade            (list all packages to be upgraded) 
  $ wajig updatealts editor    (update the default "editor")
  $ wajig restart apache       (restart the apache daemon)
  $ wajig listfiles less       (list the files supplied by the "less" pkg)

Command line options:

 -h|--help      Print usage message. 
 -n|--noauth    Allow packages from unathenticated archives.
 -q|--quiet     Do system commands everything quietly. 
 -s|--simulate  Trace but don't execute the sequence of underlying commands. 
 -t|--teaching  Trace the sequence of commands performed. 
 -v|--verbose=n Increase (or set) the level of verbosity (to n). 
 -y|--yes       Assume yes for any questions asked.

Wajig expects a command and will call upon other Debian tools to perform the command. Commands can be in mixed case and with hyphens and underscores, and internally these are mapped to the one command. Thus, the commands `Install', `INSTALL', `install' and even `in-stall' are interpreted identically.
