  16. recordmydesktop (Graphics) : Captures audio-video data of a Linux desktop session.
  17. recoverdm (Utilities) : Recover disks with bad sectors. Recover files as well complete devices. In case if finds sectors which simply cannot be recoverd, it writes an empty sector to the outputfile and continues. While recovering a CD or a DVD if the program cannot read the sector in “normal mode”, it will try to read the sector in “RAW mode”
    (without error-checking etc.). This toolkit also has a utility called ‘mergebad’ which merges multiple images into one.

  28. remake (Development) : A patched version of GNU Make that adds improved error reporting, the ability to trace execution in a comprehensible way, and a debugger.
  29. remind (Utilities) : Sophisticated calendar and alarm program. Each reminder or alarm can consist of a message sent to standard output, or a program to be executed.
  30. renameutils (Utilities) : Programs to make file renaming easier. This package consists of five programs:
    qmv: allows file names to be edited in a text editor.
    imv: allows a file name to be edited in the terminal using the GNU Readline library.
    icp: copies files.
    qcp: works like qmv, but copies files instead of moving them.
    deurlname: removes URL encoded characters (such as %20 representing space) from file names.
  31. renrot (Graphics) : Renames files according the DateTimeOriginal and FileModifyDate EXIF tags, if they exist. Otherwise, the name will be set according to the current timestamp. Additionally, it rotates JPEG images and their thumbnails, using the Orientation EXIF tag.
  32. reptyr (Miscellaneous – Text Based) : Utility for taking an existing running program and attaching it to a new terminal, and is particularly useful for moving a long-running process into a GNU screen session.

  41. rig (Miscellaneous – Text Based) : A free replacement for a shareware program out there called ‘fake’. It generates random, yet real-looking, personal data. It is useful if you need to feed a name to a Web site, BBS, or real person, and are too lazy to think of one yourself. Also, if the Web site/BBS/person you are giving the information to tries to cross-check the city, state, zip, or area code, it will check out.
  42. rinetd (Networking) : Redirects TCP connections from one IP address and port to another, with basic IP-based access control.

    – MD5 hash changes
    – files commonly created by rootkits
    – executables with anomalous file permissions
    – suspicious strings in kernel modules
    – hidden files in system directories
    and can optionally scan within files.
  44. rlplot (Mathematics) : GUI based program for displaying scientific data in standard formats. It has full support for all error-bar types and it has greater flexibility with displaying colour and texture in charts than gnuplot (filled bar chart boxes are possible without any additional programs).

  52. rsnapshot (Utilities) : Filesystem snapshot utility for making backups of local and remote systems. Using rsync and hard links, it is possible to keep multiple, full backups instantly available. The disk space required is just a little more than the space of one full backup, plus incrementals.
  53. rsstail (Word Processing) : An rss reader: it monitors an rss-feed and if it detects a new entry it’ll emit only that new entry.
  54. rsync (Netowrking) : Fast, versatile, remote (and local) file-copying tool.
  55. rtgui , rtpg-www (World Wide Web) : Web based front-end for rTorrent.
