ubuntu_logo_81x81This post covers the utilities those start with W. Part of the series.

  1. w2do (lite2do) (Utilities) : Simple to use yet efficient command-line todo manager written in Perl.
  2. w3af(-console), wapiti (Networking) : Web Application Attack and Audit Framework which aims to identify and exploit all web application vulnerabilities.
  3. w3c-linkchecker (Perl Programming Language) : Reads an HTML or XHTML document, extracts a list of anchors and links and checks that no anchor is defined twice and that all the links are dereferenceable, including the fragments. It warns about HTTP redirects, including directory redirects, and can check recursively a part of a website.
  4. w3m (Word Processing) : www browsable pager with excellent tables/frames and IPv6 support.
  5. wakeonlan (Networking) : Perl script to remotely wake up and power on machines which have motherboards or network cards that support ‘Wake-on-Lan’ packets. It uses UDP.
  6. wakeup (Miscellaneous – Text Based) : This package has a complete graphical front end with which a user can set an alarm to wake the computer – from poweroff if possible – and read a user-defined text. This text can grab relevant information (date, time, weather, Evolution schedule and tasks, news from an rss feed, number of new email messages, etc.) and speak that as well, or play music, all as defined by the user.
  7. wallch (Utility) : Wallpaper changer.
  8. watchcatd (System Administration) : A software service that monitors processes. If a monitored process locks up, it is killed.
  9. watchdog (System Administration) : System health checker and software or hardware watchdog handler.
  10. watershed (System Administration) : This utility might be run around a command such that any further attempts to run the command while another copy is running will only result in one initial further attempt.
  11. wayv (Miscellaneous – Graphical) : Experimental handwriting/gesture recognition program.
  12. wbar(-config) (Miscellaneous – Graphical) : Light and fast launch bar.
  13. wcalc (Mathematics) : Flexible command-line scientific calculator.
  14. wcd (Utilities) : Quickly change directories. It saves time typing at the keyboard. One needs to type only a part of a directory name and wcd will jump to it.
  15. wdiff (Word Processing) : A front-end to GNU diff. It compares two files, finding which words have been deleted or added to the first in order to create the second. It has many output formats and interacts well with terminals and pagers (notably with `less’).
  16. weather-util (Utilities) : Quick access to current weather conditions and forecasts.
  17. webcheck (World Wide Web) : Website checking tool for webmasters. It crawls a given website and generates a number of reports in the form of html pages.
  18. webhttrack (World Wide Web) : Offline browser utility, allowing you to download a World Wide website from the Internet to a local directory, building recursively all directories, getting html, images, and other files from the server to your computer, using a step-by-step web interface.
  19. weborf (World Wide Web) : Configurationless webserver mainly meant to allow users to easily share their directories over the web. Has limited support to webdav.
  20. webp (Graphics) : Image compression format, based on the VP8 codec. WebP uses the modern VP8 compression format to deliver efficient compression of images for the web. More than 30% extra gain over optimized JPEG, for same quality, is not unusual.
  21. weplab (Networking) : A tool designed to teach how WEP works, what different vulnerabilities it has, and how they can be used in practice to break a WEP protected wireless network.
  22. wget (World Wide Web) : Retrieve files using HTTP, HTTPS and FTP, the most widely-used Internet protocols.
  23. when (Utilities) : Minimalistic personal calendar. It runs from the command line, and it uses a plain text file format, which you can edit using your favorite editor.
  24. whereami (Networking) : A set of useful scripts and a coordinating system for automatically re-locating your computer within the current (network) environment.
  25. whichman (Utilities) : uses a fault tolerant approximate matching algorithm to search for man-pages that match approximately the specified name. The fault tolerant matching is very useful in cases where you remember only roughly the name of a command.
  26. whiteboard (Networking) : Provides a simple text editor for the web for working simultaneously and collaboratively on text documents. It’s based on mobwrite. Several markup styles for rendering to static pages views are supported: Textile, reStructured and Markdown.
  27. whowatch (System Administration) : An ncurses who-like utility that displays information about the users currently logged on to the machine, in real-time. Besides standard information (login name, tty, host, user’s process), the type of the connection (ie. telnet or ssh) is shown.
  28. wicd(-cli) (Networking) : General-purpose network configuration server which aims to provide a simple but flexible interface for connecting to networks.
  29. wikipedia2text (Word Processing) : This script fetches Wikipedia articles (currently supports around 30 Wikipedia languages) and displays them as plain text in a pager or just sends the text to standard out. Alternatively it opens the Wikipedia article in a (possibly GUI) web browser or just shows the URL of the appropriate Wikipedia article.
  30. winff(-qt) (Graphics) : Graphical video and audio batch converter using ffmpeg or avconv.
  31. winswitch (Utilities) : supports both seamless applications (via Xpra, NX and ssh) and full remote desktops (via NX, VNC, RDP). Once a session has been started via winswitch, it can be displayed on any other networked machine running the winswitch client.
  32. wipe (Utilities) : Wipe repeatedly writes special patterns to the files to be destroyed, using the fsync() call and/or the O_SYNC bit to force disk access.
  33. wmclockmon, wmclock (Miscellaneous – Graphical) : Displays a clock like wmtime, but with an alarm timer and different styles (14 + user customized ones). There’s also a “binary clock” style available.
  34. wondershaper (Networking) : Control upload and download rate of an interface.
  35. woof (Networking) : Share files across the computers on a net for a specific number of times, enough the other ends have just a browser (that means you can share things between different operating systems or different devices, even phones).
  36. worker (Miscellaneous – Graphical) : Highly configurable two-paned file manager for X.
  37. worklog (Miscellaneous – Text Based) : Keep Track of Time worked on different projects.

  39. wput (World Wide Web) : A tiny ftp-client, that uploads files or directories to a
    remote ftp-server. Main features are: resuming, time-stamping, wget-like interface, proxy-support and speed-limit.
  40. wuzzah (Miscellaneous – Text Based) : Selectively scans a system’s utmpx records (where logins are stored, among other things), keeping an eye out for your friends logging in and out, taking customizable actions on events. wuzzah is small, fast, efficient, and written in C.
  41. wxbanker (GNOME Desktop Environment) : Easily keep track of balances in accounts. Use wxBanker to add, edit, and remove transactions and accounts, make transfers, search transactions, and view a graph of balances over time. An integrated calculator also makes calculations quick and easy.
