UNIX Tutorial Two UNIX T utorial T wo http://www.ee.surrey.ac.uk/Teaching/Unix/unix2.html UNIX Tutorial Two 2.1 Copying Files cp (copy) cp file1 file2 is the command which makes a copy of file1 in the current working directory and calls it file2 What we are going to do now, is to take a file stored in an open access area of the file system, and use the cp command to copy it to your unixstuff directory. First, cd to your unixstuff directory. % cd ~/unixstuff Then at the U !" prompt, type, % cp /vol/examples/tutorial/science.txt . ote# $on%t forget the dot . at the end. &emem'er, in U !", the dot means the current directory. The a'o(e command means copy the file science.txt to the current directory, keeping the name the same. ) ote# The directory /vol/examples/tutorial/ is an area to which e(eryone in the school has read and copy access. !f you are from outside the Uni(ersity, you can gra' a copy of the file here. Use %File*+a(e ,s..% from the menu 'ar to sa(e it into your unixstuff directory.- Exercise 2a Create a 'ackup of your science.txt file 'y copying it to a file called science. a! 2.2 Mo(ing files mv (move) mv file1 file2 mo(es )or renames- file1 to file2 To mo(e a file from one place to another, use the m( command. This has the effect of mo(ing rather than copying the file, so you end up with only one file rather than two. !t can also 'e used to rename a file, 'y mo(ing the file to the same directory, 'ut gi(ing it a different name. We are now going to mo(e the file science.'ak to your 'ackup directory. First, change directories to your unixstuff directory )can you remem'er how/-. Then, inside the unixstuff directory, type 1 of 5 01/06/2009 05:05 PM UNIX T utorial T wo http://www.ee.surrey.ac.uk/Teaching/Unix/unix2.html % mv science.bak backups/. Type ls and ls 'ackups to see if it has worked. 2.0 &emo(ing files and directories rm (remove)" rm#ir (remove #irectory) To delete )remo(e- a file, use the rm command. ,s an example, we are going to create a copy of the science.txt file then delete it. !nside your unixstuff directory, type % cp science.txt tempfile.txt % ls % rm tempfile.txt % ls 1ou can use the rmdir command to remo(e a directory )make sure it is empty first-. Try to remo(e the ac!ups directory. 1ou will not 'e a'le to since U !" will not let you remo(e a non2empty directory. Exercise 2 Create a directory called tempstuff using mkdir , then remo(e it using the rmdir command. 2.3 $isplaying the contents of a file on the screen clear (clear screen) 4efore you start the next section, you may like to clear the terminal window of the pre(ious commands so the output of the following commands can 'e clearly understood. ,t the prompt, type % clear This will clear all text and lea(e you with the 5 prompt at the top of the window. cat (concatenate) The command cat can 'e used to display the contents of a file on the screen. Type# % cat science.txt ,s you can see, the file is longer than than the si6e of the window, so it scrolls past making it unreada'le. 2 of 5 01/06/2009 05:05 PM UNIX T utorial T wo http://www.ee.surrey.ac.uk/Teaching/Unix/unix2.html less The command less writes the contents of a file onto the screen a page at a time. Type % less science.txt 7ress the 8space$ ar9 if you want to see another page, and type 8%9 if you want to :uit reading. ,s you can see, less is used in preference to cat for long files. &ea# The head command writes the first ten lines of a file to the screen. First clear the screen then type % head science.txt Then type % head -5 science.txt What difference did the 2; do to the head command/ tail The tail command writes the last ten lines of a file to the screen. Clear the screen and type % tail science.txt <. =ow can you (iew the last 1; lines of the file/ 2.; +earching the contents of a file 'imple searc&in( usin( less Using less, you can search though a text file for a keyword )pattern-. For example, to search through science.txt for the word )science), type % less science.txt 3 of 5 01/06/2009 05:05 PM UNIX T utorial T wo http://www.ee.surrey.ac.uk/Teaching/Unix/unix2.html then, still in less, type a forward slash 8/9 followed 'y the word to search /science ,s you can see, less finds and highlights the keyword. Type 8n9 to search for the next occurrence of the word. (rep (#on)t as! w&y it is calle# (rep) grep is one of many standard U !" utilities. !t searches files for specified words or patterns. First clear the screen, then type % grep science science.txt ,s you can see, grep has printed out each line containg the word science. >r has it //// Try typing % grep Science science.txt The grep command is case sensiti(e? it distinguishes 'etween +cience and science. To ignore upper*lower case distinctions, use the 2i option, i.e. type % grep -i science science.txt To search for a phrase or pattern, you must enclose it in single :uotes )the apostrophe sym'ol-. For example to search for spinning top, type % grep -i 'spinning top' science.txt +ome of the other options of grep are# $v display those lines that do >T match $n precede each matching line with the line num'er $c print only the total count of matched lines Try some of them and see the different results. $on%t forget, you can use more than one option at a time. For example, the num'er of lines without the words science or +cience is % grep -ivc science science.txt wc (wor# count) , handy little utility is the wc command, short for word count. To do a word count on science.txt, type 4 of 5 01/06/2009 05:05 PM UNIX T utorial T wo http://www.ee.surrey.ac.uk/Teaching/Unix/unix2.html % wc -w science.txt To find out how many lines the file has, type % wc -l science.txt +ummary *omman# Meanin( cp file1 file2 copy file1 and call it file2 mv file1 file2 move or rename file1 to file2 rm file remove a file rmdir directory remove a directory cat file display a file less file display a file a page at a time head file display the first few lines of a file tail file display the last few lines of a file grep 'keyword' file search a file for keywords wc file count num'er of lines/words*characters in file Amazon.com C Programming Language Sams Teach Yourself Unix in Numerical Recipes 3rd Edition Brian W.

  • UNIX Version 7 Volume 1
    UNIXTM TIME-SHARING SYSTEM: UNIX PROGRAMMER'S MANUAL Seventh Edition, Volume 1 January, 1979 Bell Telephone Laboratories, Incorporated Murray Hill, New Jersey PREFACE Although this Seventh Edition no longer bears their byline, Ken Thompson and Dennis Ritchie remain the fathers and preceptors of the UNIX² time-sharing system. Many of the improvements here described bear their mark. Among many, many other people who have contributed to the further ¯owering of UNIX, we wish especially to acknowledge the contributions of A. V. Aho, S. R. Bourne, L. L. Cherry, G. L. Chesson, S. I. Feldman, C. B. Haley, R. C. Haight, S. C. Johnson, M. E. Lesk, T. L. Lyon, L. E. McMahon, R. Morris, R. Muha, D. A. Nowitz, L. Wehr, and P. J. Weinberger. We appreciate also the effective advice and criticism of T. A. Dolotta, A. G. Fraser, J. F. Maranzano, and J. R. Mashey; and we remember the important work of the late Joseph F. Ossanna. B. W. Kernighan M. D. McIlroy __________________ ²UNIX is a Trademark of Bell Laboratories. INTRODUCTION TO VOLUME 1 This volume gives descriptions of the publicly available features of the UNIX² system. It does not attempt to provide perspective or tutorial information upon the UNIX operating system, its facilities, or its implementation. Various documents on those topics are contained in Volume 2. In particular, for an overview see `The UNIX Time-Sharing System' by Ritchie and Thompson; for a tutorial see `UNIX for Beginners' by Kernighan. Within the area it surveys, this volume attempts to be timely, complete and concise. Where the latter two objectives con¯ict, the obvious is often left unsaid in favor of brevity.

  • Lab - Observing DNS Resolution (Instructor Version) Instructor Note: Red Font Color Or Gray Highlights Indicate Text That Appears in the Instructor Copy Only
    Lab - Observing DNS Resolution (Instructor Version) Instructor Note: Red font color or Gray highlights indicate text that appears in the instructor copy only. Objectives Part 1: Observe the DNS Conversion of a URL to an IP Address Part 2: Observe DNS Lookup Using the Nslookup Command on a Web Site Part 3: Observe DNS Lookup Using the Nslookup Command on Mail Servers Background / Scenario The Domain Name System (DNS) is invoked when you type a Uniform Resource Locator (URL), such as http://www.cisco.com, into a web browser. The first part of the URL describes which protocol is used. Common protocols are Hypertext Transfer Protocol (HTTP), Hypertext Transfer Protocol over Secure Socket Layer (HTTPS), and File Transfer Protocol (FTP). DNS uses the second part of the URL, which in this example is www.cisco.com. DNS translates the domain name (www.cisco.com) to an IP address to allow the source host to reach the destination host. In this lab, you will observe DNS in action and use the nslookup (name server lookup) command to obtain additional DNS information. Work with a partner to complete this lab. Required Resources 1 PC (Windows 7, Vista, or XP with Internet and command prompt access) Part 1: Observe the DNS Conversion of a URL to an IP Address a. Click the Windows Start button, type cmd into the search field, and press Enter. The command prompt window appears. b. At the command prompt, ping the URL for the Internet Corporation for Assigned Names and Numbers (ICANN) at www.icann.org. ICANN coordinates the DNS, IP addresses, top-level domain name system management, and root server system management functions.

  • HP BIOS Configuration Utility FAQ
    Technical white paper HP BIOS Configuration Utility FAQ Table of contents Feature updates ............................................................................................................................................................................ 2 Common questions ....................................................................................................................................................................... 2 For more information ................................................................................................................................................................. 12 Feature updates Version Features 4.0.2.1 Changes config file keyword to BIOSConfig. Changes commands from /cspwdfile and /nspwdfile to /cpwdfile and /npwdfile to match HP SSM. Adds /Unicode command to query if a system supports a Unicode password. Removes BIOS user commands. Maintains backwards compatibility. 3.0.13.1 Allows only one /cspwdfile command. Adds /WarningAsErr command to include warnings in the final BCU return code. 3.0.3.1 Changes commands from /cspwd and /nspwd command to /cspwdfile and /nspwdfile to read passwords from encrypted files created by HPQPswd.exe 2.60.13.1 Adds additional return codes when encountering WMI errors. 2.60.3 Add /SetDefaults command to reset BIOS to factory default. Supports configuration file comments. Common questions Q: The BIOS Configuration Utility (BCU) is an HP utility, so why it does not work on some HP platforms? A: BCU is a command-line utility for controlling various BIOS settings on a supported HP notebook, desktop, or workstation system. It requires a BIOS that supports HP WMI Namespace within the BIOS. HP began integrating CMI/WMI support directly into the BIOS during approximately 2006–2008 for managed business systems, which did not include consumer-based systems or entry-level units. If the system BIOS does not have the required WMI support, BCU does not work. This is not a failure of BCU. It is a limitation of the system BIOS that does include WMI support in the BIOS code.
