Rpm2tar is a utility for converting the contents of a binary RPM package into a gzipped tar archive. Rpm2tar attempts to preserve file ownership, groups, and permissions as they are stored in the RPM package. Rpm2tar handles files only; it does not handle pre- or post-install scripts, triggers, '%config' tags, or any other fancy features of RPM.
rewrite reads a file, feeding its content through a shell command or a pipeline, and writes it back to the file. It allows for in place (re)compression, for example. For large multi-part archives, you may not otherwise be able to uncompress and recompress the data again because of lack of temporary disk space. If the output from the pipeline is bigger than the file, the program will continue to allocate memory to buffer the difference, and it will never overwrite data in the file before reading it.
lcra renames filenames like COMMAND.COM and MAIN.C to more tasteful ones like command.com and main.c. It tries to guess which filenames are DOS-ish ones needing changing, and which are really meant to be uppercase. It will fix the contents of a directory and all subdirectories. The companion program nsra changes spaces in filenames to underscores.
The Linux Backup Utility (LBU) is a simple, menu-driven script for performing backups and restoration of data from tars, compressed tars, and tapes. It supports basic hardware compression as well as variable hardware block sizes. It lets you configure tar block sizes, exclusion lists, inclusion lists and it supports wildcards.
