Windows Command Prompt Cheatsheet
Windows Command Prompt Cheatsheet - Command line interface (as opposed to a GUI - graphical user interface) - Used to execute programs - Commands are small programs that do something useful - There are many commands already included with Windows, but we will use a few. - A filepath is where you are in the filesystem • C: is the C drive • C:\user\Documents is the Documents folder • C:\user\Documents\hello.c is a file in the Documents folder Command What it Does Usage dir Displays a list of a folder’s files dir (shows current folder) and subfolders dir myfolder cd Displays the name of the current cd filepath chdir directory or changes the current chdir filepath folder. cd ..

TRSDOS 6.2 to LS-DOS 6.3.0 Manual Update
LS-DOSÔ 6.3 UPDATE FOR TRSDOSâ 6.2.X The LS-DOS 6.3 release is an upgrade for the TRSDOS 6.2 operating system. Several important changes have been made to extend and enhance the operating system and its utilities. The date ranging has been expanded to accept dates through the year 1999. Files will now carry a modification time as well as a date. The DATECONV/CMD program is provided to translate version 6.2 or earlier disks to the 6.3 style dating. The user password has been eliminated from the system. The owner password still remains. The library command ID was added to display a customer service number. Several enhancements have been made to BASIC. The new DISKCOPY/CMD program will duplicate 5" double density floppy disks. Because the LS-DOS 6.3 update is a series of enhancements to TRSDOS 6.2, the primary documentation remains the 6.2 manual and Technical Reference manual. If you have a version of TRSDOS earlier than 6.2, you can obtain the manuals from Radio Shack under the catalog numbers 26-0316 (TRSDOS Version 6 [6.2 DOS manual and disk]), 26-2110 (Model 4/4D [6.2] Technical Reference Manual), or 26-1117 (6.2 DOS manual only). This documentation should be treated as an addendum to the TRSDOS 6.2 information. LS-DOS 6.3 installation instructions Before performing the upgrade, it is recommended that you make several backup copies of the 6.3 master disk. The simplest way to do this is to boot your system using the 6.3 diskette, insert a blank diskette to receive the copy in drive 1, and type the command: DISKCOPY :0 :1 When the copy finishes, you can insert another destination diskette and make another copy. -

Introduction to MS-DOS
1.Introduction to MS-DOS : MS-DOS (Microsoft Disk Operating System) was the Microsoft-marketed version of the first widely-installed operating system in personal computers. It was essentially the same operating system that (Bill Gates's) young company developed for IBM as Personal Computer - Disk Operating System in 1981. Most users of either DOS system simply referred to their system as Disk Operating System. Like PC-DOS, MS-DOS was (and still is) a non-graphical line-oriented command- driven operating system, with a relatively simple interface but not overly "friendly" user interface. Its prompt to enter a command looks like this: C:\> MS-DOS does not care about anything called an icon, wallpaper or screen saver. Rather than being considered as a Graphical User Interface (GUI) MS-DOS is what is known as a command-line interface. You type commands on what is called the command line. MS-DOS is a single-user, single-tasking computer operating system. In spite of its very small size and relative simplicity, it is one of the most successful operating systems that has been developed to date. In DOS, a file name consists of eight character followed by a 3 character file extension. The size of a file is restricted to a 4 byte file descriptor, which limits a file’s maximum size to approximately 4 billion characters. The first release of DOS could not read or write to disk drives so users could only read and write to a floppy disc. DOS was not a state of the art operating system, even for its time. -
Chapter 1. Origins of Mac OS X
1 Chapter 1. Origins of Mac OS X "Most ideas come from previous ideas." Alan Curtis Kay The Mac OS X operating system represents a rather successful coming together of paradigms, ideologies, and technologies that have often resisted each other in the past. A good example is the cordial relationship that exists between the command-line and graphical interfaces in Mac OS X. The system is a result of the trials and tribulations of Apple and NeXT, as well as their user and developer communities. Mac OS X exemplifies how a capable system can result from the direct or indirect efforts of corporations, academic and research communities, the Open Source and Free Software movements, and, of course, individuals. Apple has been around since 1976, and many accounts of its history have been told. If the story of Apple as a company is fascinating, so is the technical history of Apple's operating systems. In this chapter,[1] we will trace the history of Mac OS X, discussing several technologies whose confluence eventually led to the modern-day Apple operating system. [1] This book's accompanying web site (www.osxbook.com) provides a more detailed technical history of all of Apple's operating systems. 1 2 2 1 1.1. Apple's Quest for the[2] Operating System [2] Whereas the word "the" is used here to designate prominence and desirability, it is an interesting coincidence that "THE" was the name of a multiprogramming system described by Edsger W. Dijkstra in a 1968 paper. It was March 1988. The Macintosh had been around for four years. -
What Is UNIX? the Directory Structure Basic Commands Find
What is UNIX? UNIX is an operating system like Windows on our computers. By operating system, we mean the suite of programs which make the computer work. It is a stable, multi-user, multi-tasking system for servers, desktops and laptops. The Directory Structure All the files are grouped together in the directory structure. The file-system is arranged in a hierarchical structure, like an inverted tree. The top of the hierarchy is traditionally called root (written as a slash / ) Basic commands When you first login, your current working directory is your home directory. In UNIX (.) means the current directory and (..) means the parent of the current directory. find command The find command is used to locate files on a Unix or Linux system. find will search any set of directories you specify for files that match the supplied search criteria. The syntax looks like this: find where-to-look criteria what-to-do All arguments to find are optional, and there are defaults for all parts. where-to-look defaults to . (that is, the current working directory), criteria defaults to none (that is, select all files), and what-to-do (known as the find action) defaults to ‑print (that is, display the names of found files to standard output). Examples: find . –name *.txt (finds all the files ending with txt in current directory and subdirectories) find . -mtime 1 (find all the files modified exact 1 day) find . -mtime -1 (find all the files modified less than 1 day) find . -mtime +1 (find all the files modified more than 1 day) find . -
