Join Kevin Skoglund for an in-depth discussion in this video Setting command aliases, part of Unix for Mac OS X Users.
In this movie, we'll see how we can use command aliases to help us to work more…efficiently in Unix.…Now, I want to make sure that you understand that the aliases that we're talking…about here are not the same thing as the Finder aliases, right?…Remember that we can click on a file or folder, we can go to the File menu,…we can pull down and select Make Alias.…That's a Finder alias for files and folders.…That's different than what we're doing here.…What we're doing here is command aliases.…Making the same kinds of shortcuts, but shortcuts that will execute…different commands in bash.…The first command that we should learn is just simply alias by itself.…
This will return a list of all the currently defined aliases.…So right now I have none.…You probably don't either.…So to create our first one we just use the alias command again and then the…shortcut that we want to use, essentially the alias name.…So the first alias I'm going to create, I'm going to use ll.…I'm going to say ll= and then in single quotes I'll put the command that I want it to equal.…

Q: The exercise files for the following movies appear to be broken:
Is there something wrong with them?
These exercises include one or more "dot files", whose file names start with a period. These files are normally hidden from view by the Finder. So that they would show up in the Finder, the period has been removed from the file names. Additionally, "_example" has been added at the end of the file name to make it clear that the file will not work as-is.
To make the dot files usable, either:
1) Open the file in a text editor to view its contents. Note that it may not be possible to double-click the file to open it because there is no file extension (such as .txt).
2) Resave the file under a new name (usually by choosing File > Save As), adding a "." to the beginning of the file name and removing "_example" from the end.
1) Copy and rename the file from the Unix command line using the techniques discussed in this course. Rename the file by adding a "." to the start and removing "_example" from the end. Include the "-i" option to prevent overwriting an existing file unexpectedly.
Example: cp -i ~/Desktop/Exercise\ Files/Chapter_07/07_02_files/bashrc_example ~/.bashrc
