Using CHMOD - Programming for the Web

CHMOD

Changing permissions in a Linux Terminal

Advertisement:

Thanks for watching.

COMMANDS & LINKS:

chmod o+w stuff : give "others" write access to the file "stuff"
chmod o-w stuff : remove write access for "others" from "stuff"
chmod 777 stuff : give everyone all permissions to stuff (this is a very BAD idea)
chmod a-x stuff : remove exucutable permissions from "stuff"
chmod 600 stuff : owner has read & write access only to "stuff" (excellent security but not always practical)
chmod 644 stuff : owner has read & write access; group has read access; others have no access (good security)
chmod 664 stuff : owner has read & write access; group has read & write access; others have no access (default security)

NOTES:

I tend to make the videos "on the fly", there's no script and everything is done from memory with just a few notes to jog the "old, grey cells". I do apologise for the umms, ahhs, erms, and pregnant pauses in the video - men tend not to be quite as good at multi-tasking :D .

I will, when possible, copy and paste commands to make the videos a little quicker and so as to not waste your time.


BIO:

John has been working with computers for longer than he cares to remember. John trained as a Systems Analyst/Programmer, has also worked as a Systems Administrator on Windows Servers and Workstations and has been dabbling with Linux since the mid 1990s.

Along the way John has learnt and used COBOL, C, C++, Visual Basic, Delphi, PHP (HTML, CSS, JavaScript etc.), SQL, various Scripting languages and some proprietary database languages. John wrote his first website in early 1996 using Windows Notepad (no IDEs were available then) and, later, started using HotDog before moving to Dreamweaver then to NetBeans and Atom.

John, now, is freelance and develops software solely for the internet. John uses both Windows and Linux daily and develops web software in both environments using PHP, HTML, CSS (Sass & Less), SQL, JavaScript and various frameworks as the project dictates.
