Radmind is a suite of Unix command-line tools and an application server designed to remotely administer the file systems of multiple client machines.[1][2]

For Mac OS X, there is a graphical user interface called Radmind Assistant, as well as a GUI for the Radmind server called Radmind Server Manager.[3]

Radmind was the 2003 Apple Design Awards runner-up for Best Mac OS X Server Solution.[4]

How Radmind Works[edit]

Radmind operates as a tripwire, detecting changes in a client's filesystem (and, in the case of Microsoft Windows, the registry) and reversing the changes.[5][6][7] Radmind stores filesystem specifications in text files called transcripts, signified with a .T extension. Transcripts are referenced from command files, signified with a .K extension, which specify which transcripts (and with what precedence) should be applied to a client machine's filesystem.

Suite of tools[edit]

The radmind suite of tools comprises

  • ktcheck, which updates the locally stored command files and transcripts to match those on the server.
  • fsdiff, which checks the client filesystem against the transcripts on the local system without using network bandwidth.
  • lapply, which updates the client filesystem to match the transcripts, downloading files as needed.
  • lcreate, which uploads new transcripts to the server.
  • lcksum, which verifies uploaded transcripts.
  • lfdiff, which compares local files with copies on Radmind server.
  • lmerge, which combines transcripts on the server.
  • ra.sh , which automates the update process using ktcheck, fsdiff, and lapply.
  • twhich, which returns which transcript(s) a file is referenced in.
  • applefile, which allows Radmind to work with AppleSingle files.

Radmind is developed by the Research Systems Unix Group at the University of Michigan.
