regfiledump(1) Dump the contents of a Regina data file


regfiledump [ -f | -l | -n ] [ -c ] file [ packet-label ... ]


This utility dumps the contents of the given Regina data file to standard output in a human-readable format.

If a list of packet labels is given on the command-line, only those packets will be output. Otherwise all packets in the given file will be output.


-f (default)
Output full packet details. The output for each packet will cover several lines, beginning with basic details (such as the packet label and type) followed by the packet's long description.
Output a list of packet labels and types only, one packet per line.
Don't output any packets at all; this option forces a packet count (see option -c).
Finish the output with a total count of all packets in the file.


If any packets contain international characters, Regina will attempt to convert these to your local character encoding as it writes them to the output.

You can tell Regina what character encoding to use by setting standard locale-related environment variables, such as LANG, LC_CTYPE or LC_ALL.

For example, if LANG is set to en_AU then output will be written in the Western European character set ISO-8859-1, and if LANG is set to en_AU.UTF-8 then output will be written in the universal character set UTF-8.

Typically these environment variables will already be set for you when you install your GNU/Linux system, and Regina will just use the right character set out of the box. See your GNU/Linux system reference for further information on supporting different locales.


If you downloaded a drag-and-drop app bundle, this utility is shipped inside it. If you dragged Regina to the main Applications folder, you can run it as /Applications/


The command-line utilities are installed beneath the Program~Files directory; on some machines this directory is called Program~Files~(x86). You can start this utility by running c:\Program~Files\Regina\Regina~4.96\bin\regfiledump.exe.
