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.

C Programming and using getopt
 
18:37
More videos like this online at http://www.theurbanpenguin.com If we have used the command line at we should be used to providing command line options such as ping -c or ls -l; the options -l, -c etc can be read from within the program using the getopt function from the getopt.h header file. For more information you can read the man page , man 3 getopt if you are using Linux. Using the Raspbian OS on the Raspberry Pi this tutorial looks at creating a program in C that can be used to convert temperatures from Centigrade to Fahrenheit and vice versa. We will use getopt to search for the options -c and -f to ensure that the correct calculation is applied.

Using Options and getopt in C programming on the Raspberry Pi
 
12:20
Using getopt when programming in C on the Raspberry Pi makes dealing with command line arguments far more manageable. Using a while loop and switch statement we will see how we can easily manage command line input to our programs as well as making use of return values to the main function.

Bash Scripting 5 -- Arguments

A quick video covering the basics of arguments in Bash scripting. Arguments are the data that you pass in when you call a script, like "scriptname argument1 argument 2". In real life, this is something like 'tar zcf filename.tar.gz directory' ('zcf', 'filename.tar.gz', and 'directory' are the arguments in this example). $# -- number of args that our script was run with $0 -- the filename of our script $1..$n -- script arguments Full Bash Scripting Basics Playlist: https://www.youtube.com/playlist?list=PLtK75qxsQaMIlFCcFZpTBLnaCJ0I0uiaY The only non-video Bash scripting resource you need: http://tldp.org/LDP/abs/html/ Full Linux Sysadmin Basics Playlist: https://www.youtube.com/playlist?list=PLtK75qxsQaMLZSo7KL-PmiRarU7hrpnwK Check out my project-based Linux System Administration course (free sample videos): https://www.udemy.com/hands-on-linux-self-hosted-wordpress-for-linux-beginners/?couponCode=tl35 Patreon: https://www.patreon.com/tutorialinux Official Site: https://tutorialinux.com/ Twitter: https://twitter.com/tutorialinux Facebook: https://www.facebook.com/tutorialinux

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

I wrote a small program in C language in order to explain the difference between options and values in the shell. The program will obtain and print out all options as well as values passed from the shell. The truth is there's no difference between those except how it's programmed. When you successfuly compile the program (I used a command called gcc this time) you will execute the program with ./ as prefix. You will need ./ to execute the program which is outside from your PATH. The video contains all actions from creating a new directory, empty file, editing the file, compiling then executing.

Using Python and Argparse to Build Quick Scripts
 
30:43
Python is a really handy language for scripting, particularly when compared to a compiled language like C# or Java. Lets take a look at how we can use python and a python module called argparse to build simple python scripts that are extremely easy to use. Argparse is a module for python that makes adding command line arguments to your programs extremely easy. It also helps with input validation and documentation by automatically generating error messages, parsing your input and automatically creating `--help` and `-h` commands to display help for your program. This makes writing tools super easy and helps make sharing your tools with other people a lot easier. They don't need to dig into the docs anymore and can just run `python mycoolscript.py --help` to learn how to use it. You can install the argparse module using pip: ```bash pip install argparse ``` Want to explore Argparse in more depth? It's documentation includes a number of great examples and more: https://docs.python.org/3/library/argparse.html A simple example of using argparse may look like this: ```python import argparse parser = argparse.ArgumentParser(description='print a list of integers') parser.add_argument('integers', metavar='N', type=int, nargs='+', help='one or more integers to print') args = parser.parse_args() print(args.integers) ``` This will automatically validate that at least 1 integer is passed to the function and generate a help command that can be run using either `--help` or `-h`.
