megatron, unhex, unbin, unsingle, hqx2bin, single2bin, macbinary -
Macintosh file format transformer
megatron is used to transform files from BinHex, MacBinary,
AppleSingle, or netatalk style AppleDouble formats into MacBinary or
netatalk style AppleDouble formats. The netatalk style AppleDouble
format is the file format used by afpd, the netatalk Apple Filing
Protocol (AppleShare) server. BinHex, MacBinary, and AppleSingle are
commonly used formats for transferring Macintosh files between machines
via email or file transfer protocols. megatron uses its name to
determine what type of tranformation is being asked of it.
If megatron is called as unhex , unbin or unsingle, it tries to convert
file(s) from BinHex, MacBinary, or AppleSingle into AppleDouble format.
BinHex is the format most often used to send Macintosh files by e-mail.
Usually these files have an extension of ".hqx". MacBinary is the
format most often used by terminal emulators "on the fly" when
transferring Macintosh files in binary mode. MacBinary files often have
an extension of ".bin". Some Macintosh LAN-based email packages use
uuencoded AppleSingle format to "attach" or "enclose" files in email.
AppleSingle files don´t have a standard filename extension.
If megatron is called as hqx2bin, single2bin, or macbinary, it will try
to convert the file(s) from BinHex, AppleSingle, or AppleDouble into
MacBinary. This last translation may be useful in moving Macintosh
files from your afpd server to some other machine when you can´t copy
them from the server using a Macintosh for some reason.
If megatron is called with any other name, it uses the default
translation, namely unhex.
If no source file is given, or if sourcefile is ‘-´, and if the
conversion is from a BinHex or MacBinary file, megatron will read from
The filename used to store any output file is the filename that is
encoded in the source file. MacBinary files are created with a ".bin"
extension. In the case of conflicts, the old file is overwritten!
