X bytes of 0, Y bytes of random data, Z bytes of 5, T bytes of 1. ??
Hello guys. I really hope someone will help me with this one..


So, I have to write this script who:
- creates a file home/student/vmdisk of 10 mb
- formats that file to ext3
- mounts that partition to /mnt/partition
- creates a file /mnt/partition/data. In this file, there will be:
- X bytes of 0
- Y bytes of random data
- Z bytes of 1
- T bytes of 5
So, totally, the file's size, /mnt/partition/data will be X+Y+Z+T, where X,Y,Z,Y are parameters.

The big problem is with the XZTY bytes. I dont know how to make a file with X bytes of 0, Y bytes of random data, and so on.. Also how can I make a file ext3?

Definition of Bytes

A byte is the smallest unit of storage which can be accessed in a computer's memory- either in RAM or ROM.It also holds exactly 8 bits.But its old view one byte was sufficient to hold one 8 bit character.Modern days especially on .NET or international versions of Win 32, 16 bits is needed. ...

mdbfontset

mdbFontset(5)							 The m17n Library						     mdbFontset(5)

NAME

       mdbFontset - Fontset

DESCRIPTION

       The m17n library loads a fontset definition from the m17n database by the tags <fontset, FONTSET-NAME>. The plist format of the data is as
       follows:

       FONTSET ::= PER-SCRIPT * PER-CHARSET * FALLBACK *

       PER-SCRIPT ::= '(' SCRIPT PER-LANGUAGE + ')'

       PER-LANGUAGE ::= '(' LANGUAGE FONT-SPEC-ELEMENT + ')'

       PER-CHARSET ::= '(' CHARSET FONT-SPEC-ELEMENT + ')'

       FALLBACK ::= FONT-SPEC-ELEMENT

       FONT-SPEC-ELEMENT ::= '(' FONT-SPEC [ FLT-NAME ] ')'

       FONT-SPEC ::=
	    '(' [ FOUNDRY FAMILY
		  [ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]]
		REGISTRY
	     [ OTF-SPEC ] [ LANG-SPEC ] ')'

       SCRIPT is a symbol of script name (e.g. latin, han) or nil. LANGUAGE is a two-letter symbol of language name code defined by ISO 639 (e.g.
       ja, zh) or nil.

       FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font.
       See m17nFont for the meaning of each property.

       OTF-SPEC is a symbol specifyng the required OTF features. The symbol name has the following syntax.

	 OTF-SPEC-NAME ::= ':otf=' SCRIPT LANGSYS ? GSUB-FEATURES ? GPOS-FEATURES ?

	 SCRIPT ::= SYMBOL
	 LANGSYS ::= '/' SYMBOL

	 GSUB-FEATURES ::= '=' FEATURE-LIST ?

	 GPOS-FEATURES ::= '+' FEATURE-LIST ?

	 FEATURE-LIST ::= '~' ? FEATURE ( ',' '~' ? FEATURE ',' )

       Here, FEATURE is a four-letter Open Type feature.

       LANG-SPEC is a symbol specifying the required language support. The symbol name has the following syntax.

	 LANG-SPEC-NAME ::= ':lang=' LANG

       Here, LANG is a two or three-letter ISO-639 language code.

       FLT-NAME is a name of Font Layout Table (Font Layout Table).

EXAMPLE

       This is an example of PER_SCRIPT.

       (han
	 (ja
	   ((jisx0208.1983-0)))
	 (zh
	   ((gb2312.1980-0)))
	 (nil
	   ((big5-0))))

       It instructs the font selector to use a font of registry 'jisx0208.1983-0' for a 'han' character (i.e. a character whose Mscript property
       is 'han') if the character has Mlanguage text property 'ja' in an M-text and the character is in the repertories of such fonts. Otherwise,
       try a font of registry 'gb2312.1980-0' or 'big5-0'. If that 'han' character does not have Mlanguage text property, try all three fonts.

       See the function mdraw_text() for the detail of how a font is selected.
