HDA Updates

Here is a simple script that displays all of the file updates and additions made to your hda and the date they happened. It simply reads the hda-updates.log file and parses out only the relevant changes.

I use this script periodically so I can see what might have changed recently.

Installation

Log into your hda and create a bin directory under your home directory (if you don't already have one). The reason for this is that ~/bin is already in your $PATH when you log in, so it will automatically find any scripts you put there:

   cd /usr/bin

Open up your favorite editor (I suggest gedit for this) and copy the code that follows into the editor. Save the file as hda-updates (or whatever you want to name it) and exit the editor.

Code:

#!/usr/bin/python
#
# Dump update information from /var/log/hda-updates.log
#!/usr/bin/python
#
# Display the date and files that were modified/installed.
#
# Reads the hda-updates log file and parses out just the file updates/additions.
# It helps to see what has been modified and when.

# Updated by bigfoot65
# 9/26/2014

log = '/var/log/hda-updates.log'

line = '==============================================================================='
head = 'Package                 Arch            Version           Repository     Size'
cyan = '\033[1;36m'
blue = '\033[1;34m'
purple = '\033[1;35m'
white = '\033[1;37m'

print blue + line + white
print cyan + head + white
print blue + line + white

f = open(log, 'r')
lines = f.readlines()
f.close()

gotUpdates = False
firstUpdate = False
dateInfo = ''
for ll in lines :
	l = ll.strip()
	# Ignore dependency heading
	if l == 'Installing for dependencies:' :
		continue
	if l == '' :
		# A blank line terminates the updates for a particular date
		if gotUpdates :
			gotUpdates = False
		continue
	if gotUpdates :
		if firstUpdate :
			# Display the date above the first update
			print '%s:' % dateInfo
			firstUpdate = False
		# Reformat the file info slightly
		updateInfo = l.split()
		print purple + l + white
		print blue + line + white
	if 'hda update attempt' in l :
		# This header appears once per hour in the log. Very few represent real updates.
		# Save the date information in case this is a real update.
		dateInfo = ' '.join(l.split()[5:])
	if 'Updating:' in l :
		# This is a real update, set up the flags
		gotUpdates = True
		firstUpdate = True

Make the file executable:

   chmod +x hda-updates

Now you can run it.
