UNIX Help & Advice

I originally sent this as a PM to Neo, but I was ignorant towards the rule of PMing someone with technical information. Below is a copy / paste of the questions I asked. If anyone can help, I'd appreciate it tons. Thank you! Smilie

The first OS I ever encountered was DOS and Windows 3.1. Ever since then I've been using nothing but Windows ... until recently!

I just purchased a Macbook Pro and I am extremely happy with it. What makes it even better is the fact that it's UNIX-based. The Macbook has brought a new kindled interest in computers that I've lost over the years.

I've always wanted to learn about UNIX and programming in C. Right now I'm only familiar with HTML and CSS. But every time I see a command console and C code I just get happy and I'm always wondering, "What's it doing?"

I'm wondering if you could give me some advice on where to start - on where to begin this adventure. I want to learn as much as I can about UNIX and C. What books would you consider a "must have" or recommend, for a total novice? The only UNIX experience I have is installing Linux and running it for a while, and now the new addition: OS X. These are desktop-user experiences, though. I want to get my hands dirty and dig deep. I want to learn what's really going on underneath the pretty interfaces. I want to create things from scratch. I just want to know.

I've been asking a lot of professors at the local college for help, but sadly our computer science department is not that great. I'm always referred to C++ and Visual C++ when asked about programming, and it's almost always a, "Use Visual Basic if you're new." I honestly believe their philosophy is to just teach us what we need to know to get by, and not the history, art, and philosophy of a programming language - which is what I'd love to learn.

I believe I started off on the wrong foot and got lost. If I would have used a UNIX based OS 15 years ago, I think I would have been much happier. I must now start over and relearn something new (OS X), so I figure what better than to start fresh with OS X and UNIX.

mwrite(1)						      General Commands Manual							 mwrite(1)

NAME
mwrite - mtools utility to perform a low level write (copy) of a UNIX file to DOS SYNOPSIS
mwrite [-mntv] unixfile msdosfile mwrite [-mntv] unixfile [unixfiles...] [msdosdirectory] OPTIONS
Preserves the file modification time. Specifies that a warning is not issued when an existing file is specified as the target file. If this option is not specified, the mwrite command verifies whether or not to overwrite an existing file. Specifies a text file transfer. Line terminators are converted to the appropriate format. Specifies verbose mode. Displays the new file name if the UNIX file name requires conversion. DESCRIPTION
The mwrite command copies the specified UNIX file to the named DOS file, or copies multiple UNIX files to the named DOS directory. The destination directory cannot be omitted. Reasonable care is taken to create a valid DOS file name. If an invalid name is specified, the mwrite command changes the name, then displays the new name if the -v option is specified. DOS subdirectory names that contain the '/' or '' separator are supported. If you use the '' separator or wildcards, you must enclose file names in quotes to protect them from the shell. The mcd command can be used to establish the device and the current working directory (relative to DOS), otherwise the default is A:. Not all UNIX file names are supported in the DOS world. The mwrite command may have to change UNIX names to fit the DOS file name conven- tions. 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. ENVIRONMENT VARIABLES
The following environment variables affect the execution of mwrite: If set, this variable names the file that contains the name of the cur- rent mtools working directory as established by the mcd command. If this variable is not set, the file $HOME/.mcwd is used. FILES
Contains the name of the current mtools working directory as established by the mcd command. If this file does not exist, the default mtools working directory is A:. Executable file SEE ALSO
Commands: dos2unix(1) mcd(1), mcopy(1), mdiskcopy(1), mkmanifest(1), mread(1), mtools(1), unix2dos(1) mwrite(1)
