calculate in TB total used disk space by files newer than X days using find

I have a folder with thousands of large files and I would like to find the total used disk space that was created in the last X days.

I've tried this command:

find . -type f -mtime -30 -printf '%s\n' | awk '{total=total+$1}END{print total/1024}'

As mentioned here by @k-h
calculate total used disk space by files older than 180 days using find

The output of the command is 9.84347e+09 and I'm not sure how to change the output to TB disk size.

Please advise.
Thanks,

Well not quite the same logic but I'm here to explain:

{ echo -n \(; find -type f -mtime -30 -printf "%s+"; echo 0\)/1024/1024/1024/1024; } | bc

Let's break this down:

• echo -n \( - prints ( without a line break.
• find … - that same ol' command you used with the + sign for calculation.
• echo 0\)/1024… - we're printing 0 so the expression won't end with a + sign, print the closing parentheses and then dividing by 1024 four times to get to the relevant result.
• | bc - this is the calculation tool, you can simply pipe the formula to this tool, try running echo 1+2 | bc and play with it to understand its concept.

Have fun, and cool name BTW :)
