is a utility for slackware to extract information about packages which can be used in a shell pipeline.

installation

and you'll have packagetools installed.

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
