NAME ^

rpmprune - Remove unneeded files from a list of RPM package files

SYNOPSIS ^

rpmprune [ --newer ] [ --older ] [ --equal ] [ --uninst ] [ --invert ] filelist ...

DESCRIPTION ^

The rpmprune tool is a simple example of using some of the RPM Perl bindings.

With rpm version 3 and newer, multiple files given on the command-line for an install, uninstall or update command are treated as a single transaction. If any of the files in the set cannot be acted upon, the whole transaction must be rejected. This is inconvenient for casual package upgrades where a directory may have many rpm files, some of which are already installed. A command of:

    rpm -Uhv *.rpm

would fail, as one (or more) files in the set is already installed. This can lead to careless use of options such as --force.

In the simplest usage, this tool eases that situation by allowing:

    rpm -Uhv `rpmprune *.rpm`

When the back-ticks are evaluated, rpmprune has only echoed the names of those files that are either newer than their installed counterparts, or are not installed at all.

OPTIONS ^

For maximum flexibility, rpmprune supports more options than anyone will realistically put to use:

--help

Print a summary of the options and general usage.

--newer (--nonewer)

If selected, all files that are newer than their installed counterparts will be echoed. Prefix with "no" to suppress the printing of these.

--older (--noolder)

If selected, all files that are older than their installed counterparts will be echoed. Prefix with "no" to suppress them, instead.

--equal (--noequal)

If selected, all files that are the same version as their installed counterparts will be echoed. Prefix with "no" to suppress them, instead.

--uninst (--nouninst)

If selected, all files that are for packages not currently installed on the system will be echoed. Prefix with "no" to suppress them, instead.

--invert

Invert the logic of all four of the previous selectors.

Without any arguments, rpmprune acts as if the following were the command line:

    rpmprune --newer --noolder --noequal --uninst ...

The --invert option is applied last, after all others have been processed.
