Show and Hide Hidden Files.bash

# To show hidden files

defaults write com.apple.finder AppleShowAllFiles -bool YES
killall Finder

# To hide hidden files

defaults write com.apple.finder AppleShowAllFiles -bool NO
killall Finder

# Setting up keyboard shortcut

# To start, open up Automator (in the Applications folder) and choose a 
# Service template. From the library choose "Run Shell Script" and drag it 
# across to the workflow area. In the text box paste the following command:

STATUS=`defaults read com.apple.finder AppleShowAllFiles`
if [ $STATUS == YES ]; 
then
    defaults write com.apple.finder AppleShowAllFiles NO
else
    defaults write com.apple.finder AppleShowAllFiles YES
fi
killall Finder

# Finally, change the "text" drop-down menu to “no input” and then save you 
# workflow as “Toggle Hidden Files”.

# Now if you go to the Finder menu and look under Services, you should find a 
# “Toggle Hidden Files” option. To add the keyboard shortcut, go to the 
# Keyboard section of System Preferences and click the Keyboard shortcuts tab. 
# Select Services from the list on the left, then scroll down to the bottom of 
# the list on the right to find “Toggle Hidden Files”. Double-click on the 
# area to the right of it, then press the keyboard shortcut you want. 
# I used Command-Shift-. (dot).

# To use a context menu instead of a keyboard shortcut you just need to 
# follow the same instructions as above, but make some slight changes 
# in Automator. Instead, change the “text’ drop-down menu to 
# “Files and Folders” and the “any application” drop-down menu to “Finder”. 
# Now when you right-click on a file or folder in the Finder, a new 
# “Toggle Hidden Files” option should appear.
