clink replaces duplicate files in Unix filesystems with symbolic links. It can achieve good space savings, for example on automatically-generated directory structures, such as compiling toolchains. It is fast; it reads each file only once, and its runtime is mainly the time taken to read files. It also consumes very little RAM and is very easy to use.
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.
bzip2smp parallelizes the bzip2 compression process to achieve a near-linear performance increase on SMP machines. On a two-processor Xeon machine, the speedup is around 180%. The tool's main purpose is to aid performing heavy-duty server backups. It can also be used on modern desktop multicore processors (such as AMD Athlon64 X2 and Intel Pentium D).
