sysfunc is a shell library intended for Unix sysadmins. It provides a set of portable shell functions including features such as file copy, symbolic link management, file/dir deletion, user/group management, data block replacement in a file, line replacement, commenting/uncommenting lines, service management, and volume group/logical volume/file system creation.
Check_MK is a complex addon for Nagios/Icinga and consists of three subprojects. The check and inventory system Check_MK is a general purpose Nagios plugin for retrieving data. It adopts a new approach for collecting data and obsoletes NRPE, check_by_ssh, NSClient, and check_snmp. It features a significant reduction of CPU use on the Nagios host and automatic inventory of items to be checked, and is especially useful with larger Nagios installations. "MK Livestatus" gives immediate and fast access to live and historic Nagios status data. It's a supported backend for many addons including NagVis, NagiosBP, and Thruk. "Check_MK Multisite" is a feature complete replacement for the Nagios GUI, and uses MK Livestatus as a backend. It is very fast, and supports efficient distributed monitoring.
encsh is a simple tool that encrypts a shell or other interpreted script and puts a wrapper around it. The end result is an executable which, when given the correct password, will be decrypted and run through a pipe, effectively keeping the plain text of the script away from the disk.
Consh is a set of programs that can turn one or more UNIX hosts on a trusted LAN into a singular Bourne shell multi-computer on which shell scripts are run concurrently. The service abstracts hosts into what appears to be shell process with a fixed number of threads or workers, to which work may be assigned and results received concurrently. It includes utilities that assign commands to workers in parallel and a command that initiates distributed barriers between workers for synchronization purposes. Environment variables can be set on a per-host basis to implement locking mechanisms like semaphores or ticket algorithms. Daemons can delegate work to one another as needed.
selector is a command line utility for dynamic string selection. As you type a list of substrings separated by ";" or a regexp, the display is updated in real time to show only the matching lines. The main usage of selector is as an efficient search in the shell command history. With the correct option, it will inject the selected line into the terminal input buffer, allowing the user to edit the line and execute it as a standard command.
