!Delete files and folders in current folder older than 90 days
{{{
find . -type d -mtime +90 -exec rm -rf {} \;

!Size of Folder
Print current folder in kb (includes org space? it is not the sum of ls)
{{{
du -sk .

ls -l | awk '{t+=$5}END{print t}'
ls -lR . | awk '{sum += $5} END{print sum}'

exactly the sum of ls in MB
{{{
ls -lR . | awk '{sum += $5} END{printf "%2f\n", sum/1024/1024}'

ls -al | sort -nbk5 => sort by file size
ls -lrt => sort by date/time

Get sizes of folders and subfolders
{{{
du -h --max-depth=3

or a shell script:
