American Disability Act Any student who has a disability and is in need of classroom accommodations, please contact the instructor and the Services for Students with Disabilities Office in Old Library 2136 at the beginning of the semester. Scholastic Dishonesty Asking for help in understanding a problem or lending assistance to explain difficult points is encouraged. However, the copying of another student's assignment, or the common solution of written or programming assignments, or changing variable names of programming assignments, will be considered as cheating, unless group solution is specifically allowed. The purpose of assignments is to provide individual evaluation as well as a tool for learning and exploration of material. Note that the operational word in the definition of cheating is copying, not submission. Students found guilty of academic dishonesty will be subjected to disciplinary action as prescribed by the Computer Science Department's prescribed disciplinary procedures. Disciplinary action for this course includes, but is not limited to, failure for the course. Additional disciplinary action may be instituted by the Dean. .

Lecture 17 the Shell and Shell Scripting Simple Shell Scripts
Lecture 17 The Shell and Shell Scripting In this lecture • The UNIX shell • Simple Shell Scripts • Shell variables • File System commands, IO commands, IO redirection • Command Line Arguments • Evaluating Expr in Shell • Predicates, operators for testing strings, ints and files • If-then-else in Shell • The for, while and do loop in Shell • Writing Shell scripts • Exercises In this course, we need to be familiar with the "UNIX shell". We use it, whether bash, csh, tcsh, zsh, or other variants, to start and stop processes, control the terminal, and to otherwise interact with the system. Many of you have heard of, or made use of "shell scripting", that is the process of providing instructions to shell in a simple, interpreted programming language . To see what shell we are working on, first SSH into unix.andrew.cmu.edu and type echo $SHELL ---- to see the working shell in SSH We will be writing our shell scripts for this particular shell (csh). The shell scripting language does not fit the classic definition of a useful language. It does not have many of the features such as portability, facilities for resource intensive tasks such as recursion or hashing or sorting. It does not have data structures like arrays and hash tables. It does not have facilities for direct access to hardware or good security features. But in many other ways the language of the shell is very powerful -- it has functions, conditionals, loops. It does not support strong data typing -- it is completely untyped (everything is a string). But, the real power of shell program doesn't come from the language itself, but from the diverse library that it can call upon -- any program.

Lecture 1 Introduction to Unix and C
Lecture 1 Introduction to Unix and C In this lecture • Operating System • Unix system shell • Why learn C • Program Development Process • Compilation, Linking and Preprocessing • ANSI-C • The C compiler – gcc • Jobs and Processes • Killing a Process • Moving from Java to C • Additional Readings • Exercises Operating System Each machine needs an Operating System (OS). An operating system is a software program that manages coordination between application programs and underlying hardware. OS manages devices such as printers, disks, monitors and manage multiple tasks such as processes. UNIX is an operating system. The following figure demonstrates the high level view of the layers of a computer system. It demonstrates that the end users interface with the computer at the application level, while programmers deal with utilities and operating system level. On the other hand, an OS designed must understand how to interface with the underlying hardware architecture. Copyright @ 2009 Ananda Gunawardena End user Programmer Application programs OS Designer Utilities Operating System Computer Hardware Unix is an operating system developed by AT&T in the late 60’s. BSD (Berkeley Unix) and Linux, are unix-like operating systems that are widely used in servers and many other platforms such as portable devices. Linux, an open source version of Unix-like operating system was first developed by Linus Torvalds . Linux has become a popular operating system used by many devices. Many volunteer developers have contributed to the development of many linux based resources. Linux is free, open source, and have very low hardware requirements. This makes linux a popular operating system for devices with limited hardware capabilities as well as running low cost personal computers.

It just happens to be very selective about who it decides to make friends with. Unknown Initially used at Bell Labs, but soon licensed to academy (notably, U. of California, Berkeley) and commercial vendors (IBM, Sun, etc). There are two major products that came out of Berkeley: LSD and Unix. We don’t believe this to be a coincidence. Jeremy S. Anderson, Unix systems administrator Historical overview (kind of) Unix is a family of multiuser, multitasking operating systems stemming from the original Unix developed in the 1970’s at Bell Labs by Ken Thompson, Dennis Ritchie1, and others.

Shell Script: the Shell Is the Part of the UNIX That Is Most Visible to the User. It Receives and Interprets the Commands Entered by the User
Shell Script: The shell is the part of the UNIX that is most visible to the user. It receives and interprets the commands entered by the user. In many respects, this makes it the most important component of the UNIX structure. To do anything in the system, we should give the shell a command. If the command requires a utility, the shell requests that the kernel execute the utility. If the command requires an application program, the shell requests that it be run. The standard shells are of different types as There are two major parts to a shell. The first is the interpreter. The interpreter reads your commands and works with the kernel to execute them. The second part of the shell is a programming capability that allows you to write a shell (command) script. A shell script is a file that contains shell commands that perform a useful function. It is also known as shell program. Three additional shells are used in UNIX today. The Bourne shell, developed by Steve Bourne at the AT&T labs, is the oldest. Because it is the oldest and most primitive, it is not used on many systems today. An enhanced version of Bourne shell, called Bash (Bourne again shell), is used in Linux. The C shell, developed in Berkeley by Bill Joy, received its name from the fact that its commands were supposed to look like C statements. A compatible version of C shell, called tcsh is used in Linux. The Korn shell, developed by David Korn also of the AT&T labs, is the newest and most powerful.

Basic UNIX Processes and Shells
Basic UNIX Processes and Shells Shell CPU ls Kernel pico Disk NIC httpd Basic UNIX Processes and Shells Processes Processes are tasks run by you or the OS. Processes can be: ● shells ● commands ● programs ● daemons ● scripts Basic UNIX Processes and Shells Shells Processes operate in the context of a shell. The shell is a command interpreter which: • Interprets built-in characters, variables and commands • Passes the results on to the kernel The kernel is the lowest level of software running. It controls access to all hardware in the computer. Basic UNIX Processes and Shells Shells Types of shells: • /bin/sh ± Bourne shell • /bin/csh ± C shell • /bin/tcsh - Enhanced C shell • /bin/bash ± Bourne ªagainº shell • /bin/zsh ± Z shell • /bin/ksh ± Korn shell Basic UNIX Processes and Shells Shell Scripts Shell scripts are files which contain commands to be interpreted and executed by a shell. A shell is its own programming environment. Shells contain: • Variables • Loops • Conditional statements • Input and Output • Built-in commands • Ability to write functions Basic UNIX Processes and Shells Shell Scripts Specifying the shell to be used: On the first line of the file: ● Implicitly blank line ± Bourne shell # in column 1 ± C shell ● Explicitly #!/bin/sh ± Bourne shell #!/bin/csh ± C shell Basic UNIX Processes and Shells Exercise Which shell are you using? # echo $SHELL (Don©t worry about what these mean, we©ll come back to them later) Basic UNIX An Interlude How to be ªCoolº All UNIX people pronounce EVERYTHING. If you don©t you aren©t cool. Examples: • ! - bang • # - pound • awk ± awk as in ªawkwardº • grep ± grrrrrrr ep • chmod ± chaaa mod • chown ± chaa own • www ± wu wu wu Basic UNIX Processes and Shells The echo Command The echo command and the echo variable are very useful for debugging scripts.
