(a) Spend some bucks to buy a good book on Unix/Linux. Check out the reviews, the "Look Inside" feature, the "Listmania" lists at amazon.com. Or go to your neighborhood bookstore and browse through the books to get an idea of the one that suits you.

But, more importantly:

(b) Install a Unix/Linux system on your computer yourself, and practice, practice, practice. Write as many scripts as you can. Test things by yourself before believing anything.

It's like learning how to ride a bicycle or swim. A book can only give you the directions, but when the time comes, it won't write your Production code for you.

mkmanifest(1)						      General Commands Manual						     mkmanifest(1)

NAME
mkmanifest - mtools utility to create a shell script to restore UNIX file names from DOS SYNOPSIS
mkmanifest [files] OPTIONS
None OPERANDS
A list of UNIX file names to be converted to DOS name format. DESCRIPTION
The mkmanifest command creates a shell script that aids in the restore of UNIX file names that were overwritten by DOS file name restric- tions. DOS file names are uppercase only, cannot exceed 8 character names, 3 character extensions and do not support device names or non- alphanumeric characters. Not all UNIX file names are supported in the DOS world. The mtools commands may have to change UNIX names to fit the DOS file name conven- tions. Most commands provide the verbose option (-v), that displays new file names if they have been changed. The following table shows some examples of file name conversions: ----------------------------------------------- UNIX name DOS name Reason for the change ----------------------------------------------- thisisatest THISISAT file name too long file.stuff FILE.STU extension too long prn.txt XRN.TXT PRN is a device name .abc X.ABC null file name hot+cold HOTXCOLD illegal character ----------------------------------------------- EXIT STATUS
The following exit values are returned: Success. Failure. EXAMPLES
Assume you have the following UNIX files that you want to copy to a DOS diskette using the mcopy command. very_long_name 2.many.dots illegal: good.c prn.dev Capital The mcopy command converts these file names to the following: very_lon 2xmany.dot illegalx good.c xprn.dev capital To restore the previous file names, use the mkmanifest command as follows: mkmanifest very_long_name 2.many.dots illegal: good.c prn.dev Capital > manifest The previous mkmanifest command line produces the following: mv very_lon very_long_name mv 2xmany.dot 2.many.dots mv illegalx illegal: mv xprn.dev prn.dev mv capital Capital The good.c file name did not require conversion, hence it was not included in the output. If these files were copied from diskette to another UNIX system, and you wanted to restore the original names, retain a copy of the mani- fest file (captured output) so that it can be used to convert the file names again.
