Pipe Viewer (pv) is a terminal-based tool for monitoring the
progress of data through a pipeline. It can be inserted into
any normal pipeline between two processes to give a visual
indication of how quickly data is passing through, how long
it has taken, how near to completion it is, and an estimate
of how long it will be until completion.
prips is a tool that can be used to print all of the IP address on a given
range. It can enhance the usability of tools that are made to work on only
one host at a time (e.g. whois).
This package contains a command-line tool that displays as much detail
about itself and its environment as possible. It can be used as a test
tool, to understand the type of environment a process runs in, and for
comparing system environments.
"pstack" is a workalike for the Solaris program of the same name.
Running pstack on a process or core file produces a stack trace of
each thread in that process.
It's useful for finding out what wedged processes are up to, getting
profiles of what applications, and just satisfying one's curiosity.
filelike is a Python module for building and manipulating file-like
objects.
This module takes care of the groundwork for implementing and manipulating
objects that provide a rich file-like interface, including reading,
writing, seeking and iteration. It also provides a number of useful
classes built on top of this functionality.
This package provides an API for querying the distutils metadata written in
the PKG-INFO file inside a source distribution (an sdist) or a binary
distribution (e.g., created by running bdist_egg). It can also query the
EGG-INFO directory of an installed distribution, and the *.egg-info stored in
a "development checkout" (e.g, created by running setup.py develop).
Pdsh 是一个高效的、多线程的远程 shell 客户端,在多个远程主机上并行地执行
命令。Pdsh 实现了动态扩展功能,例如新的远程 shell 服务和远程主机选择。
Capistrano is a standalone utility that can also integrate nicely with
Rails. You simply provide SwitchTower with a deployment "recipe" that
describes your various servers and their roles, and voila! You magically
have single-command deployment. It even allows you to roll a bad version
out of production and revert back to the previous release.
SCSI / firewire harddrive spindown daemon
This is a small program for handling automated spinning down of
SCSI harddrives. With SCSI devices it is not as common to spindown
for power management purposes as for ATA however it might be required
to spin down a disk contained in a firewire enclosure for instance.
Murder is a method of using Bittorrent to distribute files to a large amount
of servers within a production environment. This allows for scaleable and
fast deploys in environments of hundreds to tens of thousands of servers
where centralized distribution systems wouldn't otherwise function.
