Are you stuck, wondering how to deal with the invisible files in your Mac Finder? Read on to find out how to handle them in Finder, Terminal and in Open Dialog boxes, as of OS X 10.11.3 “El Capitan”.

Handling Hidden Files in OS X

Mac OS X is basically a * nix system at its heart, so it has the concept of hidden files, and sometimes you want to see those. These invisibles are things like:

  • ~.bash_history your bash history log
  • .git/ the special folder in any git repository, that contains all the info about the same

There are several areas in OS X where you might need to display them, so I’ll show you how to do that for each.

Hidden files in Finder

The standard way to show hidden files in the Finder, is to issue the command defaults write in Terminal. (Scroll the code window to its right to see the rest of the command, if it’s cut off.)

defaults write AppleShowAllFiles TRUE
killall -KILL Finder

Oddly enough, defaults write takes “true”, “yes” or “1” to mean the same thing.

You can hide the hidden files again like this, therefore:

defaults write AppleShowAllFiles FALSE
killall -KILL Finder

You can read the status of this setting, like this:

defaults read AppleShowAllFiles

Or, get that result to a variable, and then echo the variable:

showallfiles=$(defaults read AppleShowAllFiles); echo $showallfiles

The $() around the defaults read means, “run this command”. The semicolon acts as a command separator. The echo puts the value assigned to the variable on the terminal output, aka “standard out” or std-out.

Bash it into a script

Alright, so let’s pop these commands into a bash script, for convenience, so it can be run easily, any time. Create a text file called, say, in your home folder, using a text editor, and paste the text below into it (or download a zip from here).

# Author: Rick Cogley
# Created: 19 Feb 2016
showallfiles=$(defaults read AppleShowAllFiles)
case "$showallfiles" in
1|TRUE|True|true|YES|Yes|yes) defaults write AppleShowAllFiles -boolean false
  echo Hidden files covered
*) defaults write AppleShowAllFiles -boolean true
  echo Hidden files showing
killall Finder

The script has the usual “sh-bang” #!/bin/bash line at the top, which indicates it’s a bash script, a bit of commented information, then it grabs the setting and puts it into the variable $showallfiles. Then it uses a case statement to check the value in the variable against a bunch of possibilities (1 or TRUE or True etc), running defaults write to set the AppleShowAllFiles to the opposite of what it is now.

Now mark the script as executable, and run it. Assuming it’s in your home folder, the dance goes like this:

cd ~
chmod +x

Just run it again to toggle. The hidden files will appear and disappear, in reaction to running the script.

Run it from anywhere

If you’d like to run the script from any path, you can make a symlink to it. Let’s say you saved the script in ~/scripts. That’s not in your path, so you can simply do this:

cd /usr/local/bin
ln -s ~/scripts/

Now, just enter from any folder and it should run.

There are a couple other methods to show invisible files or folders in Finder:

  • If you use CocoaTech’s Path Finder, you can toggle invisibles via Shift-Cmd-i or View, Show Invisible Files. This is for viewing them within Path Finder.
  • If you use Maintain’s Cocktail, you can toggle hidden files via Interface, Finder, Show Invisible Files.
  • If you use Finder’s “Go” menu, hold down option when you click it, to display hidden folders inside.

Hidden files in Open Dialogs

If you want to toggle invisibility in a File, Open dialog, you can press:


… while the dialog is open. Just be sure you’ve switched the view into “list” mode. You can press cmd-2 to do that from within the File, Open dialog, or, from Finder itself. Try cmd-1, cmd-2 and cmd-3.

Hidden files at the Terminal

Finally, if you’re using the Terminal, you can list hidden files in a folder like this:

cd ~
ls -a
.                                .rnd                             .zshrc-backup2
..                               .spf13-vim-3                     .zshrc-e
.489454.padl                     .ssh                             .zshrc.local
.499167.padl                     .subversion                      .zshrc.pre-oh-my-zsh
.CFUserTextEncoding              .v8flags.  Applications
.DS_Store                        .vim                             Creative Cloud Files
.Trash                           .vimbackup                       Desktop
.atom                            .viminfo                         Documents
.bash_history                    .vimrc                           Downloads
.bzr.log                         .vimrc.before                    Dropbox
.cache                           .vimrc.bundles                   Google Drive

That’s list all (-a) in a compact format. You can also try ls -la for a long list view.

In Conclusion

So now you have a couple of techniques for showing invisible files in OS X:

  • Use a bash script and some GUI options, to toggle hidden files in Finder.
  • Link the bash script into your system path, so it will run from any folder in Terminal.
  • Peek at hidden files in File, Open dialogs using a hot-key: shift-cmd-..
  • List hidden files at the Terminal with ls -a or ls -la.

These are verified to work in OS X 10.11.3 “El Capitan” and probably work fine for earlier versions too. Thanks for dropping by, and please share with others if you found this useful.
