exiftool : rename files in current dir to YYYY-MM-DD-HH-MM-SS-1.ext

mediaName

# Function for your .zshrc file
# Requirements: install the package manager Homebrew (http://brew.sh), then install exiftool (type brew install exiftool in Terminal.app).

# Renames image and MOV files according to EXIF capture date, using YYYY-MM-DD-HH-MM-SS.ext format. 
# Files shot within the same second get copy number added (-1,-2, etc.).
# Video files require a different, so we run exiftool 3 times:
# 1. Exclude MOV files and rename the image files with <CreateDate>.
# 2. Target MOV files and rename them with MediaCreateDate (for iPhone videos).
# 3. Target MOV files and rename them with DateTimeOriginal (for Fuji camera videos).

# Note: --ext EXCLUDES files with the extension, while -ext INCLUDES files with that extension

@parhuzamos Great catch! Thanks so much! Updated and wrapped this as a function now called mediaName()
