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

BASH  All about aliases
 
08:56
More videos like this online at http://www.theurbanpenguin.com We learn about aliases, shortcuts to commands and options in the shell. Mostly the command ls is aliases to ls --color=auto so we have to just type ls to get the full command options in the alias. We can temporarily stop the alias and run the native command using the backslash to precede the command, \ls. to delete the alias we can use unalias ls in this case. We can always create aliases of our own using the alias command, ie alias fd='find -maxdepth -type d'. Should we wish to disable the use of aliases within the shell then we can set the BASH option shopt -u exapand_aliases.

I wanted to make a tutorial on Bash on Windows 10 for quite a while. March 30, 2016, Microsoft announced the anniversary update, which would bring a ton of features to Windows 10. It seems that August 2, 2016, Microsoft will release the anniversary update that will contain Bash. Before August 2, we will need to get the Insider build for 14316. Requirement 0) Check that you have 64 bit Windows 10! You must have 64 bit System Type. 1) Search for your "Version" and "OS Build" numbers. Hit the Start button. Hit Settings. Hit System. Hit the About left side tab. Look at the Version and OS Build. We're looking for at least Build 14316 of Windows 10. If you have at least Build 14316, skip to Step 5. 2 [NO LONGER NEEDED. SKIP.] ) Sign up for the Windows Insider program with your Microsoft Account. https://insider.windows.com/ 3 [NO LONGER NEEDED. SKIP.) You don't have to do this step anymore, but instead, you do need to make sure that your PC is updated. Search for Advanced Windows Update options. Underneath Get Insider Preview builds, hit Get started. You may be asked to Restart your computer. Fast ring. 4) Search for Update. Click on Check for updates. Click on For developers on the left side tab. Click on Developer mode. 5) 6:36 Open up the Control Panel. Hit Programs. Click Turn Windows Features On or Off. Enable Windows Subsystem for Linux (Beta). Click OK. 6) Restart Now to reboot your computer, and Windows 10 will install the new feature. 7) After the computer restarts, click the Start button and find bash. 8) Type y in the black terminal window to download Bash on Ubuntu on Windows. 9) You can search Bash on Ubuntu on Windows to use bash anytime. 10) sudo apt-get update sudo apt-get install packagename 11) You cannot access software installed from the Bash shell like apt-get packages from the Windows Command Prompt or somewhere else on Windows.

Shell Scripting Tutorial for Beginners 11 - Floating point math operations in bash | bc Command
 
12:22
For more detailed Tutorial visit - https://goo.gl/ZrJh1a bc, for basic calculator (often referred to as bench calculator), is "an arbitrary-precision calculator language" with syntax similar to the C programming language. bc is typically used as either a mathematical scripting language or as an interactive mathematical shell. bc [ -hlwsqv ] [long-options] [ file ... ] bc is a language that supports arbitrary precision numbers with interactive execution of statements. There are some similarities in the syntax to the C programming language. A standard math library is available by command line option. If requested, the math library is defined before processing any files. bc starts by processing code from all the files listed on the command line in the order listed. After all files have been processed, bc reads from the standard input. All code is executed as it is read. (If a file contains a command to halt the processor, bc will never read from the standard input.) -------------------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

Data + Coding in Bash - episode 4 - Best Practices & Shortcuts (data science for beginners)
 
13:18
My Website: https://data36.com Newsletter: https://data36.com/newsletter-subscription/ Whole article: https://data36.com/data-coding-bash-best-practices/ Twitter: https://twitter.com/data36_com ***************** Note: If you are new here, I suggest to start with these previous data coding and/or bash articles: Data Coding 101 – Install Python, R, SQL and bash! - https://data36.com/data-coding-101-install-python-sql-r-bash/ Data Coding 101 – Intro to Bash ep#1 - https://data36.com/data-coding-101-introduction-bash/ #1 Tab key: Any time when you start typing in the command line and you hit the TAB key, it automatically extends your typed-in text, so you can spare some characters. #2 Up/down arrows: They help you to bring back your previous commands. So if you misspelled something or if you want to do a small modification, you don’t have to type the whole command again. #3 history --» This bash tool prints your recently used commands on your terminal screen. (Pro tip: try it with grep! Eg. history |grep 'cut' will list you all the commands you have used and contained cut.) #4 CTRL + R or clear: It cleans your screen. Better for your mind, better for your eyes! #### First install CSVKit! sudo pip install csvkit Note: First I’ve heard about the CSVKit bash tools in this book: Jeroen Janssen - Data Science at the Command Line. #5 csvlook helps you to see your csv files in a much cleaner, much processable-by-humans format. Eg. here’s a short sample from our flightdelays.csv file: cat 2007.csv |head |cut -d',' -f12,13,14,15| csvlook #6 csvstat gives you back some basic statistics about your dataset. Try: cat demo1.csv | csvstat (Even median is there! Remember last time how hard it was to get it?) Note: csvstat is unfortunately not so great with bigger files. So you can’t use it for the flightdelays.csv for example, because that file is way too big. #7 Enter-enter-enter This will sound dummy, but I assure you this is a real problem and this is a real solution for it. This is what data scientists do, when they use command line in real life. The problem: when you cat a file on your screen, then another one right after, it’s really hard to find the first row of the second file. The main reason is, that the prompt looks like every other line in your files. If you’ve watched the video above, you have seen, that I colored my prompt. That’s part of the solution, but to make sure I will find the first line of my second file, before the second cat I usually hit 10-15 blank enters. #8 man --» this is a bash command to learn more about specific command line tools. Eg. try: man cat --» and you will get into the manual of cat. It works for almost every command. (man cut, man grep, etc…) The good thing in it is that in each manual you can find a great list for all the options for the given command. #9 Googling + StackOverflow I know this is something I should not even mention, but still: if you have a question, you can be sure that someone has already asked it and another one has already answered it somewhere on the internet. So just don’t forget to use Google first. Most of the answers are on a website called StackOverflow - by the way. If it’s accidentally not there, Stackoverflow is still awesome, because you can also ask questions there. There are many nice and smart people there, from whom you will get an answer fast, so don’t be shy! ;-) #10 A great book about Data Science at the Command Line Jeroen Janssen - Data Science at the Command Line datascienceatthecommandline.com As far as I know, this is the one and only book that writes about bash as a tool for data scientists. It comes with many great tips and bash best practices! It assumes that you have some initial Python and/or R knowledge, but if you don’t, I still recommend it. If you have read my Data Coding 101 articles about bash so far, it won’t cause any issue the understand the most of this nice book! Conclusion Today we went through some great tools to make your job in bash cleaner, faster and smarter. Next week I’ll show you two major control flow components of bash: the if command and the while loops. (And they are even more important, as we are gonna use the same logic later in Python and R as well!)
