Join Kevin Skoglund for an in-depth discussion in this video Finder aliases in Unix, part of Unix for Mac OS X Users.
Over the course of the next several movies I want to take a look at how to…work with links in Unix.…Conceptually, links are similar to file aliases that you create in the Mac OS X Finder.…You may already be familiar with those, but they're not the same thing and it's…important for us to understand the differences between them.…We'll start by taking a look at the way that the Mac OS X Finder aliases work.…And to begin with, let's just create a simple file.…So notice that I am already inside my unix_files directory and I'll create a new file.…I'll call it linkedfile.txt and in it, I'll just put some sample text, Link test.…
Ctrl+X to exit, yes to save the changes, and return to accept the name that…it wanted to give me.…Now if we do ls -la, we can see that file we just created right here.…Notice that the size of the file is 10.…That's because there are just ten characters in it.…That's what it's storing and keeping track of, and it's just a normal regular file here.…That's what this dash at the beginning indicates.…
