RegEx for packages and filenames

regexp could be something like 'pkgname*' '*file*' or similar
e.g. opkg info 'libstd*' or opkg search '*libop*' or opkg remove 'libncur*'

Options

       -A                      Query all packages not just those installed
       --cache <directory>     Use a package cache
       -d, --dest <dest_name>  Use <dest_name> as the the root directory for
                               package installation, removal, upgrading.
                               <dest_name> should be a defined dest name from
                               the configuration file, (but can also be a
                               directory name in a pinch).
       -f, --conf <conf_file>  Use <conf_file> as the opkg configuration file
       -o, --offline-root <dir> Use <dir> as the root directory for
                               offline installation of packages.

       --force-downgrade       Allow opkg to downgrade packages
       --force-maintainer      Overwrite preexisting config files
       --force-overwrite       Overwrite files from other package(s)
       --force-reinstall       Reinstall package(s)

configuration files

In SHR the files are located in the directory /etc/opkg/ opkg.conf contains the main config options

arch.conf defines the priorities for different feeds/package trees/architectures

*-feed.conf contain the source type, a name and the path to the packages (comparable to debian)

Tricks

Reinstall all installed packages

At one point I ended up doing a complete upgrade before i had updated my opkg. As a result i borked a lot af packages. To reinstall them all, you can use this little sed magic.

opkg --force-reinstall install `opkg list_installed | sed 's/ - .*//'`

Upgrade after downloading all needed packages

To make sure that opkg upgrade does not break your system because of an unstable connection do:

opkg update
opkg --cache cachedir --download-only upgrade
opkg --cache cachedir  upgrade

Add a line "option cache cachedir" to /etc/opkg/opkg.conf to avoid the --cache option on command line.
