NAME

checksumgen - checksum file generator for RPM packages

SYNOPSIS

checksumgen [ options ] REPODIR ARCH
checksumgen [ options ] -l RPMLIST | --rpms=RPMLIST

DESCRIPTION

checksumgen is a tool to generate *.chksum files for selected files in RPM packages. By default all executable ELF files, Linux kernel image, modules, and the firmware are included in the generated checksum files.

The default invocation mode expects a path to an RPM repository (REPODIR) and an architecture name (ARCH). The alternative mode can be used to calculate checksums of the given RPM files (RPMLIST mode).

OPTIONS

-b BASELIST, --baselist=BASELIST: Calculate checksums only for packages with names listed in BASELIST file.
-f VLIST, --pkglist=VLIST: Calculate checksums only for packages for which name-version is found in VLIST (for instance, in a list-rpms.txt file of mkimage-profiles).
-l RPMLIST, --rpms=RPMLIST: Calculate checksums for RPM files by reading their paths from RPMLIST file (incompatible with REPODIR and ARCH params).
-p PSUMS, --prev=PSUMS: Calculate checksums for new RPMs only with relation to previous checksum file PSUMS.
-d DELSED, --delsed=DELSED: Output a sed script to delete the checksums of removed and replaced RPMs to DELSED file.
-u, --update: Delete outdated checksums on the fly and output a complete checksum file (requires PSUMS).
-c, --concat: Append new packages and versions to the given PSUMS file and output a complete checksum file.
-o SUMS, --out=SUMS: Write output to SUMS.
-a, --append: Append the output to SUMS.
-m MISSINGS, --missings=MISSINGS: Write filenames of RPM files not found under REPODIR to the MISSINGS file (the default is ./missings).
--list-keys: List public key fingerprints for selected packages (i. e.: BASELIST and/or including PSUMS) and exit.
-j NPROC, --nproc=NPROC: Use up to NPROC parallel threads (the default is nproc(1) output).
-I PATTTERN, --include=PATTERN: Include files with path matching the given PATTERN (this option may be specified multiple times). The PATTERN syntax is mostly like a shell glob pattern syntax with additional support for double-asterisk ** pattern that matches any substring including slash /. Moreover, the special /**/ pattern matches zero (!) or more subtree items making /usr/lib/python3/site-packages/**/*.py match /usr/lib/python3/site-packages/hyperlink/test/common.py and also /usr/lib/python3/site-packages/six.py whereas /usr/lib/python3/site-packages/*/**/*.py does not.
--no-default: Do not use the default include patterns. By default, the following include patterns are used:

•: ./lib/modules/*/**/*.ko,
•: ./lib/modules/*/**/*.ko.*,
•: ./lib/firmware/**/*.

: Additionally, files of the following types are also included by default regardless of their path:

•: ELF files,
•: Linux kernel image files,
•: boot executable image files.

: The option disables this behaviour.
-n, --no-fakeroot: Do not use fakeroot.
-v, --verbose: Be verbose.
-V, --version: Print program version and exit.
-h, --help: Show help text and exit.
