Developer Approach For Command Line

1. Developer Approach For Command Line RONAK R SAMPAT (ronak.sampat@multidots.com)
2. Why Command Line? We are Developers, not End Users. ($developer == true) ? ‘CLI + GUI’ : ‘GUI’;
6. What Experts Say ……. ➔ “People drive cars with steering wheels and gas pedals. Does that mean you don’t need wrenches ?” - Rob Pike (A team member of the Unix Development Team) ➔ “Everyone knows the answer to the question of life, the Universe and everything, but for the first time we can reveal the question. It is this : How many command line tricks must a man memorise? You see graphical user interfaces are all well and good, but you want to get the real work done, it is time to switch to the terminal !!” - TuxRadar (Linux Format Magazine)
7. Key Things …… ➔ Command line interfaces are often prefered by the more advanced users, as they often provide a more concise and powerful means to control a program or an operating system. ➔ Programs with command line interfaces are generally easier to automate via scripting. ➔ Command line interfaces for softwares other than operating system includes a number of programming languages such as Tcl/Tk, PHP and others as well as the utilities such as the compression utilities such as WinZip and UltimateZip and some FTP and ssh/telnet clients
14. Why Command Line Is Standard Whereas GUIs Are Not ? ➔ GUIs are the result of the distributed powers of the command line which brings some default stints attached to it as GUIs without a doubt user friendly but are drivers driven, getting the perfect output sometimes depend on the up-to-date & functionally available UI drivers, whereas this is not the dependency with the command line, you can check for or look for anything anytime. ➔ As above statement stated, command lines are power holding and GUIs are a distributed power representation of command line, so the command line is bound to provide the requested output on the spot as well as on occasional basis as required, whereas in the case of GUIs it becomes sometimes tedious to do clicks here and there to check for the little thing that we are looking for.
15. Examples ….. ➔ What if I want to just copy my .jpeg files from /images/ to /imagesJpeg/ ? In GUIs it is to select all the .jpeg files from the set of files holding ctrl key or search for .jpeg from the search bar and then copy all files …. Reach to destination /imagesJpeg/ and paste all of them simultaneously, whereas in command line it is just a matter of three words. ➔ If I want to look for hosts.ini file in the C: drive then I just need to type C:\>dir /s hosts.ini and it will return more than even I am looking for…. The path where it its located, the size of the file, total number of files if they are found on multiple locations, plus the full information about both the files at the same time, whereas in GUIs it is the matter of few clicks
16. Most Interesting Sources To Look For Command Line ➔ https://channel9.msdn.com/Events/TechEd/NewZealand/2014/DCIM324 ➔ http://video.ch9.ms/sessions/teched/nz/2014/DCIM324_FINAL.mp4 ➔ http://www.tuxradar.com/content/command-line-tricks-smart-geeks
17. The solution Learning Commands is an investment of few time, the rest is the way to the ………. --------- EXPERTISE ----------
19. Some Useful Package Managers & Libraries …... - While windows is a UI centric system, there are some amazing package managers in its bag ….. 1) Chocolately 2) OneGet 3) Scoop 4) Ninite Want to install Chrome ? Just … choco install GoogleChrome (No need to specify the versions, just correct package name is enough)
20. Want to run linux commands on windows ? ……. - Cygwin A Large Collection Of GNU and open source tools which provide functionality similar to LInux Distribution on Windows. (https://www.cygwin.com/) - npm Short for Node Package Manager, is two things: first and foremost, it is an online repository for the publishing of open-source Node.js projects. Second it is a command line utility that aids in package installation, version
21. Basic File Manipulation & Restrictions… D:\>robocopy D:\ronak\ronak\learning D:\ronak\learning /e D:\ronak\ronak\Learning>xcopy *.png D:\ronak\newLearning
22. Basic File Manipulation & Restrictions… - Search For Any File / Dir Within System -dir /s /AD something.txt ( *.txt) - Open File in your favourite text editor setx path "%path%;c:\directoryPath" - C:\>yourFavouriteEditor.exe yourFile
23. Basic File Manipulation … - Create a directory and set restrictions - C:\pathToParentDir>mkdir yourDesiredDir - C:\pathToParentDir>cd yourDesiredDir - C:\pathToParentDir>attrib +r yourDesireDir
24. Basic File Manipulation … - Set User Specific Restriction - icacls pathToYourDirOrFile /grant Administrator:(N,WDAC) - Difference Between Two Files - C:\>FC file1 file2 (Same as svn does for us!!)
25. Basic File Manipulation … - Dump The OutPut Of Any Command To The Text File - C:\>FC file1file2 > file3 - PowerShell To Edit Files In Command Line PS C:\> get-content file1.txt | add-content file2.txt - C:\Users\ronak pc\Documents\something>cipher /R:something.txt
26. Start Stop XAMPP/WAMPP With CLI - WAMPP : - NET START wampapache64 - NET START wampmysqld64 - xampp : - C:\xampp\apache\bin>httpd -k start - C:\xampp\mysql\bin>mysqld
27. Setting Up Virtual Host Through CLI - Want to do everything within CLI ? Simple ….. Choco install nano and follow the following commands. - C:\>runas /user:MD003\admninistrator cmd - C:\>notepad windows/system32/drivers/etc/hosts - In it put 127.0.0.1 yourDomain.local - C:\>notepad xampp/apache/bin/conf/httpd.conf
28. Setting Up Virtual Host Through CLI - Remove # from infront of Include conf/httpd.conf - (Starting virtual hosts configuration extra feature in xampp) - C:\>notepad xampp/apache/bin/conf/extra/httpd-vhosts.conf
29. Setting Up Virtual Host Through CLI <VirtualHost *:80> ServerAdmin webmaster@wordpressCore.com DocumentRoot "C:/xampp/htdocs/wordpress-core/build" ServerName wordpress-core.local ##ErrorLog "logs/dummy-host2.example.com-error.log" ##CustomLog "logs/dummy-host2.example.com-access.log" common </VirtualHost>
30. Let’s Have Fun….. First of all lets see who our neighbours are ….. Lets see who our neighbours are …. C:\>NET VIEW Got stucked? Check where the error has happend … C:\>scf /VERIFYONLY Protecting Your System Is In Your Hands …...sfc /SCANNOW Verify Specific File ... sfc /VERIFYFILE=c:\windows\system32\kernel32.dll
31. Want to play with your windows and LAN ? Taste the below commands with attaching “/?” in the end ….. - C:\>wmic - C:\>tracert - C:\>netstat
