Unix Book
A book that I've had success with is: UNIX Shells, by Ellie Quigley. It has some typos in it but it's rather good.

mkmanifest
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.
