# associated with TextMate to be associated with Sublime Text 2
# instead.

# DISCLAIMER: worked for me, might not work for you. Use at your
# own risk. I accept no responsibility if you trash your system.

# Specify the plist file we need to tweak
plist="$HOME/Library/Preferences/com.apple.LaunchServices.plist"

# Backup the current file
cp $plist $plist.$(date "+%Y%m%d")

# Convert the plist to JSON format
/usr/bin/plutil -convert json $plist

# Replace instances of "com.macromates.textmate" with "com.sublimetext.2"
/usr/bin/perl -pi -e 's/com\.macromates\.textmate/com.sublimetext.2/g' $plist

# Convert back to binary format
/usr/bin/plutil -convert binary1 $plist

# Reset the launch services DB to pick up the new settings. 
# Not 100% sure you actually need to do this but doesn't seem 
# to do any harm
