Tool tip: dropbox-restore

I’m currently rather sleep-deprived and prone to doing stupid things. Like this, for example:

rsync -av ~/Dropbox /path/to/backup/directory/

where the directory /path/to/backup/directory already contains a much-older Dropbox directory. So when I set up a new machine, install Dropbox and copy the Dropbox directory back to its default location – hey! What happened to all my space? What are all these old files? Oh wait…I forgot to delete:

rsync -av --delete ~/Dropbox /path/to/backup/directory/

Now, files can be restored of course, but not when there are thousands of them and I don’t even know what’s old and new. What I want to do is restore the directories under ~/Dropbox to the state that they were in yesterday, before I stuffed up.

Luckily Chris Clark wrote dropbox-restore. It does exactly what it says on the tin. For example:

python /Camera\ Uploads 2014-07-22

Thanks Chris!

Dropbox tip continued: convert a file tree to HTML

A couple of posts ago, I outlined a small bash script to generate an index.html file, containing links to other files in a directory. This was for generating links to files in a Dropbox public directory.

I had completely forgotten about the very useful UNIX/Linux command named tree. If not installed, it should be in your distribution repository (e.g. sudo apt-get install tree for Ubuntu/Debian). Then simply:

cd Dropbox/Public/mydirectory
tree -H . > index.html
Next, navigate to index.html at the Dropbox website and you should see something like the tree on the right. It’s a little ugly and obviously, not as convenient as something like Github, but can be a good quick and dirty fix if you need to share a hierarchy of directories and files.

A quick Bash tip: add an index.html file to a Dropbox public folder

You know that Dropbox is terrific, of course. No? Go and check it out now.

One issue: files in your Public folder have a public URL, that you can send to other people. Unfortunately, directories do not. So how do you share a public directory full of files?

Answer: create an index.html file and share that. Let’s say that your files end in “.txt” and reside in ~/Dropbox/Public/entrez. Do this:

cd ~/Dropbox/Public/entrez
echo "<ol>" > index.html
for i in `ls *.txt`; do echo "<li><a href='$i'>$i</a></li>" >> index.html; done
echo "</ol>" >> index.html

Now you can share the link to the index.html, which when clicked will display a list of links to all the other files in the directory.
