dos2unix (installed with this application)
What is it?
dos2unix is a tool to convert text files from DOS line endings (carriage return + line feed) to Unix line endings (line feed). It is also capable of conversion between UTF-16 to UTF-8. Invoking the unix2dos command can be used to convert from Unix to DOS. This tool comes in handy when sharing files between Windows and Linux machines.
Why would I need this tool?
While editing files on a machine running some form of Windows and uploading them to a Linux server is convenient, it can cause unforeseen complications. Windows-based text editors put special characters at the end of lines to denote a line return or newline. Normally harmless, some applications on a Linux server cannot understand these characters and can cause the service to not respond correctly. There is a simple way to correct this problem: dos2unix.
The dos2unix command is a simple way to make sure that files that have been edited and uploaded from a Windows machine to a Linux machine work and behave correctly.

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. # # radioz # 11/8/2010 # # 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.
