NetConnect is a command line tool for automating the login process to routers, switches, or UNIX hosts and any intermediate devices or proxies in the path. It does this by using credentials supplied within a configuration file. It also allows users to run Perl based scripts on a single device or devices in parallel to automate tasks. Although it was originally designed around Cisco routers and switches, it can be extended to work with any CLI based device by specifying custom prompts that different devices use. It works well with Cisco routers and switches as the concepts around "enable" mode and the corresponding syntax of the prompt are contained within the source. Devices can be stored within your configuration file, so you are able to connect to devices using a portion of their name (using regular expressions) as opposed to having to remember IP addresses or full DNS names.
The parallel project allows for simple parallel and distributed processing from shell scripts. In particular, the programs accept lines of shell code on the standard input and run these lines in parallel. The parallelism can be either on the local machine or on a cluster, if a small amount of time is taken to set up SSH. Additionally, the distributed version includes a degree of fault tolerance.
Dim is a utility to help you track the changes of items (sets composed of multiple files). It provides commands to handle the complete lifecycle of version control operations: create a library, register users (code authors), create items, save local versions, branch, clone, export, import, remove, merge, archive, replicate library content over the network or the filesystem, and access the full history and browse differences at the library, item, file, line, or word level. Dim is a single self-documented POSIX shell script. It just uses standard Unix utilities like awk, diff, tar, and openssl.
ns4 is a command line configuration management tool that runs on a Unix or Windows based operating system. It allows the automated backup of node (i.e. routers and switches) configurations to an FTP/SFTP server or local media on a daily basis to create configuration archives. It can run ad-hoc commands on multiple nodes as well as custom scripts for automating complex tasks. It uses Perl and allows you to manipulate the output of commands using regular expressions within scripts. Configuration based cartridges are used to specify new node types, allowing the user to extend its functionality in a simple and dynamic way.
Freedup finds and eliminates duplicate files by linking them, and thus reduces the amount of used disk space within one or more file systems. By default, hardlinks are used on a single device, symbolic links when the devices differ. A set of options allows you to modify the methods of file comparison, the hash functions, the linking behavior, and the reporting style. You may use batch or interactive mode. Freedup usually only considers identical files, but when comparing audio or graphics files, you may elect to ignore the tags.
Archive2iso takes a directory tree and randomizes the files in the tree to stripe the files across several ISO files that can be archived or burned off to a CD. The ISO files are generated by calling the CDiso.pm module. It reads an array generated by an INCLUDE LIST so the ISO file can be made with mkisofs. The intended use is to stripe files across multiple CD/DVD randomly so if one disc is damaged all the files that were in the same directory will not be lost since files are spread across multiple disks. The actual files themselves are not split; all files remain in their original state.
flipflip's podcast downloader is a script that downloads podcasts. Is has options to limit the number of podcasts to download, to rename the downloaded files based on rules, and to tag the MP3 files with custom content or with content derived from the feed metadata. The program is very small and has very few dependencies (id3v2 and wget).
ibistools is a small set of command-line tools that aid a PCB designer working with IBIS models. It currently consists of a full IBIS v4.1 parser and an IBIS to SPICE translator. IBIS (I/O Buffer Information Specification) is a standard, human-readable, machine-readable format for publishing IC specifications.
