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.
BZip2/OSS-QM is the OSS-QM project's branch of bzip2, which contains a lot of fixes not yet in the original upstream. The primary goal is to provide QM'ed/fixed versions of upstream releases, so they can be built and used without additional patches, especially in sysrooted crosscompiling environments.
MyPurgeLogs is a script that can delete files older than a number of days and can rotate and compress other files. It simply reads a configuration file to know what it must do. Wildcards for directories and files are allowed. The compression's method is determined to optimize the free space on the filesystem. This script has only been tested on AIX.
