The following bash function (e.g. stored in your ~/.bash_aliases) finds all files within a directory that was changed on a specific date. I use this to retroactively check on all my activities throughout a day. For code-related changes, a filtered git log certainly is better, but this includes file downloads, modified text documents in one search query, if aimed at my home directory.

How to list subdirectories recursively with total size
Just a note to myself, as I always have a hard time understanding the find manpages. To list the directories and subdirectories up to a certain depth, “simply” enter:
find . -maxdepth 2 -type d
Option maxdepth states how deep the subdirectories should be listed, option type restricts output to directories (d).
If a directory listing including size is required, this much shorter snippet does the trick, using du (disk usage), the counterpart to the often-used df (disk free):
du -hd 1
Option h triggers human-readable output, replacing size byte count (5820) with SI prefixed numbers (5.8K), while d limits the recursion depth like before.
How to list size of directories in current folder
Note to self, it’s deceptively simple, once one manages to read the manpages properly:
du -hd 1 /path/to/directory
If directory is the current folder, this shortens to:
du -hd 1
