This tool is part of the Sambasuite.
This tells make_smbcodepage if it is compiling (c) a text format code page file to binary, or (d) de-compiling a binary codepage file to text.
This is the codepage we are processing (a number, e.g. 850).
This is the input file to process. In the c case this will be a text codepage definition file such as the ones found in the Samba source/codepages directory. In the d case this will be the binary format codepage definition file normally found in the lib/codepages directory in the Samba install directory path.
A text Samba codepage definition file is a description that tells Samba how to map from upper to lower case for characters greater than ascii 127 in the specified DOS code page. Note that for certain DOS codepages (437 for example) mapping from lower to upper case may be non-symmetrical. For example, in code page 437 lower case a acute maps to a plain upper case A when going from lower to upper case, but plain upper case A maps to plain lower case a when lower casing a character.
A binary Samba codepage definition file is a binary representation of the same information, including a value that specifies what codepage this file is describing.
As Samba does not yet use UNICODE (current for Samba version 2.2) you must specify the client code page that your DOS and Windows clients are using if you wish to have case insensitivity done correctly for your particular language. The default codepage Samba uses is 850 (Western European). Text codepage definition sample files are provided in the Samba distribution for codepages 437 (USA), 737 (Greek), 850 (Western European) 852 (MS-DOS Latin 2), 861 (Icelandic), 866 (Cyrillic), 932 (Kanji SJIS), 936 (Simplified Chinese), 949 (Hangul) and 950 (Traditional Chinese). Users are encouraged to write text codepage definition files for their own code pages and donate them to email@example.com. All codepage files in the Samba source/codepages directory are compiled and installed when a 'make install' command is issued there.
These are the input (text) codepage files provided in the Samba source/codepages directory.
A text codepage definition file consists of multiple lines containing four fields. These fields are:
lower: which is the (hex) lower case character mapped on this line.
upper: which is the (hex) upper case character that the lower case character will map to.
map upper to lower which is a boolean value (put either True or False here) which tells Samba if it is to map the given upper case character to the given lower case character when lower casing a filename.
map lower to upper which is a boolean value (put either True or False here) which tells Samba if it is to map the given lower case character to the given upper case character when upper casing a filename.
The location of the server and its support files is a matter for individual system administrators. The following are thus suggestions only.
The original Samba software and related utilities were created by Andrew Tridgell. Samba is now developed by the Samba Team as an Open Source project similar to the way the Linux kernel is developed.
