Required Arguments

it can be used without any argument, and then will apply on all packages

Options

-help
Print a brief help message and exits.
-man
Print the manual page and exits.
-version
Print the program release and exit.
-verbose
The program works and print debugging messages.
-use-cache
the rpm query may be long (10 to 30 s). If you will run an rpmorphan tool several time, this option will allow to gain a lot of time : it save the rpm query on a file cache (first call), then use this cache instead quering rpm (others calls).
-clear-cache
to remove cache file. Can be used with -use-cache to write a new cache.
-exclude
this option will specify the packages to exclude from the output. Can be used as '--exclude pac1 --exclude pac2' or '--exclude "pac1, pac2"'
-install-time
install-time is a filter on the period from the package installation date to now (in days). if set positive, it only allow packages installed before x days. if set negative, it only allow packages installed since x days.
-access-time
access-time is designed to filter packages which have not been used since x days.

be careful : this option will slow the program
-fullalgo
for a small list of packages, rpmusage use a different quicker methode : rpm -e --test

this option can be used to force the use of the full algo
-package
search if the given package(s) is(are) orphaned. Can be used as '--package pac1 --package pac2' or '--package "pac1, pac2"'
-all
apply on all installed packages. The output should be interpreted. For example lilo or grub are orphaned packages, but are necessary to boot ...

the "-install-time" and "-access-time" options may be useful to filter the list
-guess-perl
This option tries to find perl modules. It tries to match "^perl"
-guess-python
This option tries to find python modules. It tries to match "^python"
-guess-pike

-guess-ruby

-guess-doc
This option tries to find documentation packages. It tries to match "-doc$"
-guess-data
This option tries to find data packages. It tries to match "-data$"
-guess-dev
This option tries to find development packages. It tries to match "-devel$"

-guess-custom
this will allow you to specify your own filter. for exemple "^wh" will match whois, whatsnewfm ...

Usage

display all packages in access date order

rpmusage.pl --all | sort -k 2 -n

only ask for perl packages

rpmusage.pl --guess-perl | sort -k 2 -n

to read the output : "python-pexpect 97 on /usr/share/doc/python-pexpect" means the package was last used 97 days ago and the more recently used file was the /usr/share/doc/python-pexpect file

Files

/tmp/rpmorphan.cache : cache file to store rpm query. The cache file is common to all rpmorphan tools

Dependencies

rpmusage uses only standard perl module.

but it needs the rpm command tool.

Bugs and Limitations

the software can only work with one version of each software : we only treat the first version seen

Configuration

the program can read rcfile if some exists. it will load in order

/etc/rpmorphanrc

~/.rpmorphanrc

.rpmorphanrc

In this file,

# are comments,

and parameters are stored in the following format : parameter = value

example :

all = 1

curses = 1

Incompatibilities

not known

Diagnostics

to be written

Notes

this program should be used as root superuser, because it needs to access (in read mode) to all files
