Useful tools on Ubuntu (Z)

ubuntu_logo_81x81This post covers the utilities those start with Z. The last article of the series. I started with this exercise on 18 Nov, 2013 for spreading an awareness on the useful but sometimes lesser known utilities available by default on the Ubuntu repositories. Quite happy to draw the line after going through more than 45,000 packages on Synaptic Package Manager single-handed.

  1. zathura (Graphics) : PDF viewer with a minimal interface.
  2. zenity (GNOME Desktop Environment) : Display graphical dialog boxes from shell scripts.
  3. zerofree (System Administration) : Zero free blocks from ext2, ext3 and ext4 file-systems.
  4. zeroinstall-injector (System Administration) : Cross-distribution packaging system.
  5. zeya (Multimedia) : Media player that lets you bring your music to any computer with a web browser.
  6. zim (Miscellaneous – Graphical) : Graphical text editor based on wiki technologies.
  7. zipcmp, zipmerge (Utilities) : Compare, merge zip utilities.
  8. ziproxy (Networking) : Forwarding HTTP proxy server aimed to speed up low-bandwidth connections. It does so by gzipping HTML and using lossy compression of GIF, PNG and JPEG pictures. Ziproxy also offers JPEG 2000 support, transparent proxying and more.
  9. zoneminder (Networking) : Video camera security and surveillance solution. ZoneMinder is intended for use in single or multi-camera video security applications, including commercial or home CCTV, theft prevention and child, family member or home monitoring and other domestic care scenarios such as nanny cam installations. It supports capture, analysis, recording, and monitoring of video data coming from one or more video or network cameras attached to a Linux system.
  10. zoomer (Graphics) : Generate a video from a picture by zooming from one point to another.
  11. zorp (Networking) : A next generation, open source proxy firewall with deep protocol analysis. Zorp GPL allows you to inspect, control, and modify traffic on the application layer of the ISO/OSI model. Decisions can be made based on data extracted from the application-level traffic (for example, HTTP) and applied to a certain traffic type such as users or client machines.
  12. zsh (Shells) : A shell designed for interactive use, although it is also a powerful scripting language.
  13. zssh (Networking) : Interactive file transfers over ssh.
  14. zutils (Utilities) : A collection of utilities able to deal with any combination of compressed and uncompressed files transparently. The provided utilities are:
    zcat – Decompresses and copies files to standard output.
    zcmp – Decompresses and compares two files byte by byte.
    zdiff – Decompresses and compares two files line by line.
    zgrep – Decompresses and searches files for a regular expression.
    ztest – Tests integrity of compressed files.
    zupdate – Recompresses files to lzip format.
