Useful tools on Ubuntu (I)

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

  1. i7z(-gui) (System Administration) : Reports Intel Core i7, i5, i3 CPU information about Turbo Boost, frequencies, multipliers etc. and comes with a top-like display showing per core the current frequency, temperature and times spent in the C0/C1/C3/C6/C7 states. Includes an i7z_rw_registers script that allows toggling Turbo mode or set multipliers.
  2. iat (Cross Platform) : Iso9660 Analyzer Tool is a tool for detecting the structure of many types of CD-ROM image file formats, such as BIN, MDF, PDI, CDI, NRG, and B5I, and converting them into ISO-9660.
  3. ibam (Utilities) : Advanced battery monitor for laptops, which uses statistical and adaptive linear methods to provide accurate estimations of minutes of battery left or of the time needed until full recharge. This software relies on either APM, ACPI, SYSFS or PMU kernel support to access the battery status.
  4. icecast2 (Multimedia) : A versatile multimedia streaming server which can create (for instance) a private jukebox or “Internet radio station”. It supports Ogg streaming using the Vorbis and Theora codecs, as well as other formats such as MP3, AAC, or NSV, and is compatible with most media players.
  5. icecream (Networking) : A non-interactive stream download utility written in Perl. It connects to icecast and shoutcast servers or direct stream URLs, and redirects all fetched content to stdout and/or to media files on your disk. Other features:
    • Listen to the stream piping the output to a stdin-capable media player.
    • Save the stream to a named file or split it into different tracks.
    • It is possible to redirect the stream and save it to disk at the same time.
  6. icheck (Development) : A tool for statically checking C interfaces for API and ABI changes. All changes to type declarations that can cause ABI changes should be detected, along with most API changes. icheck is intended for use with libraries, as a method of preventing ABI drift.
  7. icmptx (Networking) : A program that allows a user with root privileges to create a virtual network link between two computers, encapsulating data inside of ICMP packets.
  8. id3/id3ren/id3tool/id3v2 (Multimedia) : Tools to edit ID3 tags of music files and rename.
  9. idjc (Miscellaneous – Graphical) : Graphical shoutcast/icecast client.
  10. ifetch-tools (World Wide Web) : Collect images from IP based cameras, monitor the collection process, and provide an interface to view the collected history.
  11. ifstat (Networking) : A tool to report network interfaces bandwidth just like vmstat/iostat do for other system counters. It can monitor local interfaces by polling the kernel counters, or remote hosts interfaces using SNMP.
  12. iftop (Networking) : Displays bandwidth usage information on an network interface.
  13. igal2/imageindex (World Wide Web) : Program that can generate HTML picture galleries.
  14. iipimage-server (World Wide Web) : Web-based streamed viewing and zooming of ultra high-resolution images.
  15. ike(-qtgui) (Networking) : The Shrew Soft VPN client is a free IPsec VPN Client for FreeBSD, NetBSD, Linux and Windows operating systems. This product can be used to communicate with Open Source VPN servers (e.g. ipsec-tools) as well as some commercial VPN servers.
  16. ilohamail (World Wide Web) : IlohaMail is a PHP based lightweight full featured multilingual webmail program with IMAP and POP3 support. IlohaMail also includes a full-featured contacts manager, bookmarks manager, and scheduler.
  17. indent (Development) : C language source code formatting program.
  18. inoticoming (Utilities) : A daemon to watch a directory with Linux’s inotify framework and trigger actions once files with specific names are placed in there.
  19. ipcalc (Networking) : Takes an IPv4 address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design sub- and supernetworks.
  20. iwatch (System Administration) : A realtime filesystem monitoring program. It’s a simple perl script to monitor changes in specific directories/files and send email notification immediately.
  21. iwyu (Development) : Analyze #includes in C and C++ source files to include only what you use.
