Shell Scripting Tutorial for Beginners 4 - Pass Arguments to a Bash-Script
 
08:35
Passing arguments to a shell script Any shell script you run has access to (inherits) the environment variables accessible to its parent shell. In addition, any arguments you type after the script name on the shell command line are passed to the script as a series of variables. The following parameters are recognized: $* Returns a single string (``$1, $2 ... $n'') comprising all of the positional parameters separated by the internal field separator character (defined by the IFS environment variable). [email protected] Returns a sequence of strings (``$1'', ``$2'', ... ``$n'') wherein each positional parameter remains separate from the others. $1, $2 ... $n Refers to a numbered argument to the script, where n is the position of the argument on the command line. In the Korn shell you can refer directly to arguments where n is greater than 9 using braces. For example, to refer to the 57th positional parameter, use the notation ${57}. In the other shells, to refer to parameters with numbers greater than 9, use the shift command; this shifts the parameter list to the left. $1 is lost, while $2 becomes $1, $3 becomes $2, and so on. The inaccessible tenth parameter becomes $9 and can then be referred to. $0 Refers to the name of the script itself. $# Refers to the number of arguments specified on a command line. -------------------Online Courses to learn---------------------------- Blockchain Course - http://bit.ly/2Mmzcv0 Big Data Hadoop Course - http://bit.ly/2MV97PL Java - https://bit.ly/2H6wqXk C++ - https://bit.ly/2q8VWl1 AngularJS - https://bit.ly/2qebsLu Python - https://bit.ly/2Eq0VSt C- https://bit.ly/2HfZ6L8 Android - https://bit.ly/2qaRSAS Linux - https://bit.ly/2IwOuqz AWS Certified Solutions Architect - https://bit.ly/2JrGoAF Modern React with Redux - https://bit.ly/2H6wDtA MySQL - https://bit.ly/2qcF63Z ----------------------Follow--------------------------------------------- My Website - http://www.codebind.com My Blog - https://goo.gl/Nd2pFn My Facebook Page - https://goo.gl/eLp2cQ Google+ - https://goo.gl/lvC5FX Twitter - https://twitter.com/ProgrammingKnow Pinterest - https://goo.gl/kCInUp Text Case Converter - https://goo.gl/pVpcwL -------------------------Stuff I use to make videos ------------------- Stuff I use to make videos Windows notebook – http://amzn.to/2zcXPyF Apple MacBook Pro – http://amzn.to/2BTJBZ7 Ubuntu notebook - https://amzn.to/2GE4giY Desktop - http://amzn.to/2zct252 Microphone – http://amzn.to/2zcYbW1 notebook mouse – http://amzn.to/2BVs4Q3 ------------------Facebook Links ---------------------------------------- http://fb.me/ProgrammingKnowledgeLearning/ http://fb.me/AndroidTutorialsForBeginners http://fb.me/Programmingknowledge http://fb.me/CppProgrammingLanguage http://fb.me/JavaTutorialsAndCode http://fb.me/SQLiteTutorial http://fb.me/UbuntuLinuxTutorials http://fb.me/EasyOnlineConverter

For more detailed Tutorial visit - https://goo.gl/bbvi0C A shell script is a computer program designed to be run by the Unix shell, a command-line interpreter. The various dialects of shell scripts are considered to be scripting languages. A shell usually interprets a single line of input, but we can also create a file containing a number of lines of commands to be interpreted. This file is a program known as a shell script. The program can also contain control structures (if-then, loops). Shell scripts allow a sequence of commands to be executed automatically . -------------------Online Courses to learn---------------------------- Data Analytics with R Certification Training- http://bit.ly/2rSKHNP DevOps Certification Training - http://bit.ly/2T5P6bQ AWS Architect Certification Training - http://bit.ly/2PRHDeF Python Certification Training for Data Science - http://bit.ly/2BB3PV8 Java, J2EE & SOA Certification Training - http://bit.ly/2EKbwMK AI & Deep Learning with TensorFlow - http://bit.ly/2AeIHUR Big Data Hadoop Certification Training- http://bit.ly/2ReOl31 AWS Architect Certification Training - http://bit.ly/2EJhXjk Selenium Certification Training - http://bit.ly/2BFrfZs Tableau Training & Certification - http://bit.ly/2rODzSK Linux Administration Certification Training-http://bit.ly/2Gy9GQH ----------------------Follow--------------------------------------------- My Website - http://www.codebind.com My Blog - https://goo.gl/Nd2pFn My Facebook Page - https://goo.gl/eLp2cQ Google+ - https://goo.gl/lvC5FX Twitter - https://twitter.com/ProgrammingKnow Pinterest - https://goo.gl/kCInUp Text Case Converter - https://goo.gl/pVpcwL ------------------Facebook Links ---------------------------------------- http://fb.me/ProgrammingKnowledgeLearning/ http://fb.me/AndroidTutorialsForBeginners http://fb.me/Programmingknowledge http://fb.me/CppProgrammingLanguage http://fb.me/JavaTutorialsAndCode http://fb.me/SQLiteTutorial http://fb.me/UbuntuLinuxTutorials http://fb.me/EasyOnlineConverter

getopts function | Working with Flags / Options - Tech Arkit
 
06:50
getopts optstring name [args]. getopts is used by shell procedures to parse positional parameters. optstring contains the option characters to be recognized; if a character is followed by a colon, the option is expected to have an argument, which should be separated from it by white space. The colon and question mark characters may not be used as option characters. Each time it is invoked, getopts places the next option in the shell variable name, initializing name if it does not exist, and the index of the next argument to be processed into the variable OPTIND. OPTIND is initialized to 1 each time the shell or a shell script is invoked. When an option requires an argument, getopts places that argument into the variable OPTARG. The shell does not reset OPTIND automatically; it must be manually reset between multiple calls to getopts within the same shell invocation if a new set of parameters is to be used. When the end of options is encountered, getopts exits with a return value greater than zero. OPTIND is set to the index of the first non-option argument, and name is set to ?. getopts normally parses the positional parameters, but if more arguments are given in args, getopts parses those instead.

Mum Experiments With Dangerous Linux Terminal Commands In theShell 7.0 (2017)
 
42:34
Any Linux user knows that the terminal is a very powerful tool. With great power though, comes great responsibility as some commands can wreck havoc on your system. The Death Command Roulette Game starts at 9:52 so skip to that if you are low on time. Diana will be given a list of 13 different terminal commands. 9 of these will be perfectly harmless, while 4 will be extremely dangerous. Will Diana be able to figure out which commands are safe while avoiding the destructive commands? Keep watching to find out! theShell is based on Arch Linux, although, please note that not all commands shown in this video can be executed on theShell right out of the box. Some of the commands such as "cowsay" require extra terminal packages to be installed via pacman. You can download theShell from here: https://sourceforge.net/projects/theos/files/ This advanced task was suggested by patreon supporter MightyEagle73. Check out his channel here: https://www.youtube.com/motrpshouse Please note that our Patreon is now closed, no new requests are accepted, we are just finishing old requests.

GOTO 2013 • Power Use of UNIX • Dan North
 
30:04
This presentation was recorded at GOTO Aarhus 2013. #gotocon #gotoaar http://gotocon.com Dan North - Agile Troublemaker, Developer, Originator of BDD ABSTRACT Thus begins an old, and sadly lost in the mists of Usenet, love story about Vi and Ed (who becomes her "ex"), told entirely in Unix commands. I had no idea when I started learning these arcane (guess how the "dd" command got its name) and cryptic (what about "grep"?) Unix commands how incredibly useful they would become over the next two decades. If your primary OS is Linux or OSX on the desktop, and maybe iOS or Android on the move, you'll find this 40-something year joke ("Unix" itself was a bad pun) has managed to embed itself into every facet of your technological life. Being comfortable at a shell prompt and having a healthy working knowledge of Unix commands and regular expressions will give you a whole new level of capability. In this fun talk I'll introduce a few commands and shell tricks you should have in your back pocket, and show you how to start taking control of your operating system. If you ask nicely I'll even tell you about the production system I wrote using Makefiles. https://twitter.com/gotocon https://www.facebook.com/GOTOConference http://gotocon.com #Unix #Grep
