Method of showing/hiding hidden files tested and working on Mac OS X El Capitan.
It seems like every day I search Google for the command to show hidden files on Mac OS X, not to mention Googling for the command to then hide those hidden files a few minutes later.
How to Hide Files and Folders on your Mac using the Hider 2 App. Now you know how to hide your secrets with the Terminal. However, there is another easier way to hide files and folders on your Mac. The app I talk about is called Hider 2. It has an excellent and thoughtful interface, so you’ll understand how to use it in a couple of minutes. After I did that, the TV displayed the visible mp3 files & played them. Today, I tried to search for hidden mp3 files on the flash drive using Finder. When I use the Terminal to show the hidden files, hidden folders are shown, but none of the hidden mp3 files are shown. Yet the hidden mp3 files are shown in Windows XP.
Today I decided to make a short and easy to remember alias to speed up the process. All I need do now is type showFiles and hideFiles whenever I need to show/hide OS X's hidden files. Here's how you can do it too.
The Quickest Way to Show/Hide Hidden Files
Since the release of macOS Sierra, when in Finder, it is now possible to use the shortcut:
Press once to show hidden files and again to hide them. If you're using a version earlier than macOS Sierra, see Show/Hide Hidden Files using Terminal Aliases to setup a toggle command via terminal.
Thanks to Guido Schlabitz for making me aware of this new shortcut.
Show/Hide Hidden Files the Long Way
The long way to show hidden Mac OS X files is as follows:
- Open Terminal found in Finder > Applications > Utilities
- In Terminal, paste the following:
defaults write com.apple.finder AppleShowAllFiles YES - Press return
- Hold the 'Option/alt' key, then right click on the Finder icon in the dock and click Relaunch.
This will show all hidden files. To hide them again, follow the same steps but replace the Terminal command with:
It's not the longest set of instructions or the biggest command to commit to memory but if you're doing this a lot, it's worth spending a few minutes now to save yourself a lot more time in the future.
Show/Hide Hidden Files using Terminal Aliases
A Terminal alias is a name or shortcut for one or multiple commands. Using an easy to remember alias, we can turn the above four step process into just one.
An alias can be made temporarily (just for the use of one terminal session) or permanently. As we want this to be a shortcut used now and in the future, let's make it permanent:
- Open Terminal found in Finder > Applications > Utilities
- In Terminal, paste the following:
sudo nano ~/.bash_profile - Enter your Mac's administration password if required, then hit return
- At the bottom of the open .bash_profile file, paste the following:
alias showFiles='defaults write com.apple.finder AppleShowAllFiles YES; killall Finder /System/Library/CoreServices/Finder.app' Below that, paste the following:
alias hideFiles='defaults write com.apple.finder AppleShowAllFiles NO; killall Finder /System/Library/CoreServices/Finder.app'- Press ctrl + O and hit return to save the file
- Press ctrl + X to exit the file and return to the command line
- In Terminal, paste the following:
source ~/.bash_profileto refresh your profile and make the aliases available
Now when you want to show hidden files, all you need type in Terminal is showFiles, then hideFiles when you want to hide them.
If you want to modify the behaviour or alias names, let's take a closer look at the commands you just added:
alias tells Terminal we're adding a new alias.
showFiles is the name of the alias. Change this to what you wish.
We then give the alias two commands. The first being:
This is the command to show hidden files and is ended with a semi-colon ; so we can then use the second command:

This will relaunch the Finder (to replicate the step of holding the 'Option/alt' key then right clicking the Finder icon in the dock).

Conclusion
With the aliases set up, all you need do in the future is type showFiles and hideFiles to show and hide Mac OS X's hidden files respectively.
Aliases can be used to speed up your interaction with the Terminal. Set up an alias for navigating to your most used directories, to commit to a GitHub repo and so on.
