#usage of packagetools

-available
  	list repository packages
-list
  	list installed packages
-local string
  	directory of package install logs (default "/var/log/packages")
-prefixes string
  	package subdirs in repository to consider (default "./patches/packages ./slackware64")
-repo string
  	path to repository (only CHECKSUMS.md5 and FILELIST.TXT are required) (default "/mnt/mirror/slackware/slackware64-14.2")
-upgrade
  	list upgradeable packages

#output format

For -available and -list the output format is a tab-seperated list of name, version, arch, build, unix time of modification, file path

For -upgrade the output is similar, only that the first six fields are information about the local package and the last six fields information about the repository package.

#usage examples

this assumes the default location for repositories is valid.

#find all packages which can be upgraded, except kernel packages, and print a download url for the package and the signature

for x in $(packagetools -upgrade | grep -v "kernel" | cut -f 12); do
	echo "http://ftp.slackware.com/pub/slackware/slackware64-14.2/$x"
	echo "http://ftp.slackware.com/pub/slackware/slackware64-14.2/$x.asc"
done

#search a specific package in the repository and display the name, version and build

packagetools -available | grep "bash" | cut -f 1,2,4
