GNU parallel is a shell tool for executing jobs in parallel locally or using remote computers. A job is typically a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. If you use xargs today you will find GNU parallel very easy to use, as GNU parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU parallel as input for other programs.
rocknroll (Rsync fOr baCKup and Roll) is an incremental backup maker based on rsync. It backs up a remote directory tree to a destination directory on the local host. For this backup, it manages a set of archives named tag.1, tag.2, etc. Using the famous "link-dest" option of rsync, it keeps only the difference between the different archives.
Yasma (Yet Another Sendmail Logfile Analyzer) is a reporting tool for sendmail log files. It provides a nice overview of your mail traffic like: messages transferred, some average values, top lists of messages sent, received, rejected, etc., and top lists of supposed spammers, status messages, relay hosts, and mailers. It analyzes one or more log files from the command line and writes an HTML report. For security, it can hide the user part of mail addresses listed in the report. A GeoIP database can be used to show country information.
Vimv is a utility to help rename various files at once using a text editor. It opens the list of files in a directory inside a text editor (vi by default). Then, any changes made in the editor will be reflected in the filesystem (the files in the directory will be renamed to the names saved in the editor).

Quota Check is a simple application which is designed to run when a user logs into a computer. If they have less than a certain amount of free disk quota, they are told to visit the system administrator and are logged out. When a user tries to log into a network home directory which has a quota enforced, and they don't have enough disk space, they risk corrupting their files. Quota Check makes this situation very clear to users who may be otherwise unaware of the problem.
