Linux Web Server Soft Link URL Tutorial
We were wondering if Linux (and can work on unix) soft links, as talked about with Linux and Unix Soft Links Primer Tutorial, can be of practical value pointing to the source code of a webpage. Perhaps you’d want to do this regarding restrictions applied to executionable server code, such as PHP.
We decided to try this with our new AlmaLinux9 web server (cded to web server Document Root) via …
# ln -s PHP/exif_tester.php ./exif_tester.php
… for a tweaked exif_tester.php old style invocation with this new AlmaLinux9 new style invocation from Document Root with success, because of the changed internal image relative URL considerations. This capability is not universal regarding Linux web servers.
Interesting, huh?!

Linux and Unix Soft Links Primer Tutorial
Are there big differences between the Linux and Unix operating system, and Windows, for example? Deep at the heart of the very file orientated Unix and Linux operating systems (where just about everything can be boiled down to being about files) are the possibilities presented by Soft Links (or Symbolic Links), a concept missing in the original design of Windows/DOS. So, as is pretty apparent, there are some huge differences, which partly explains the passion some people feel for their favourite operating system … or favourite anything … it is the “tribal” in us methinks.
For myself, prefer to marvel at the good bits of (the whole gamut of) all these approaches to software (and cherrypick the appropriate/good ones for any particular problem/issue), and have to say, Soft Links, as a concept, in Unix and Linux, was (and is) one of the best things ever invented, and if it was everywhere (on other operating systems) who knows, maybe there would have been some internationalization on this area of I.T., and approaches could have seen the concept used more powerfully (and fully) than now (mind you, maybe it is, and I just need somebody to share their deep insights?! … please feel free, in the comments) in cute ways that would have opened up many more useful ways to program code that is cross-platform-friendly (or “networked”).
Background reading for tutorial:
Let’s see some Linux and Unix Soft Links Primer Tutorial steps of interest, hopefully. These are presented via a Mac laptop’s Terminal application, whose default shell environment is Bash.
Link to some downloadable code … rename to soft_link_tutorial.sh (bit specific to local conditions, but please tailor for your own use).
