free space via MEGAcmd needs to be calculated

[gidici]

MEGAcmd version

1.7.0

Operating System/Platform

Linux

Platform version. In the case of Linux, please enter the Linux distribution you are using.

Debian 12

Steps

In a bash shell I try to calculate the free available space in my MEGA cloud; I have read the MEGA commands, but haven't find a command to get the free space as one single number to be used in bash scripts.

Expected behavior

I would like to get the free available space with just one command; currently I need to write
used=$( mega-df | grep "USED STORAGE:" | awk -F'[^0-9]' '$0=$2')
total=$(mega-df | grep "USED STORAGE:" | awk -F'[^0-9]' '$0=$5')
free=$((total-used))
However, mega-df and mega-du doesn't return the same value; e.g.
mega-df returns
USED STORAGE: 21051345911 39.21% of 53687091200
(Cloud drive=20309471541 + Rubbish bin=741874370 = 21051345911)
while mega-du returns 20304533872
Thank you for your help

Actual behavior

1. I have to calculate the free space by myself (see above)
2. mega-df and mega-du don't give the same result; I don't know which one should I use

1. Feature request noted. Thanks!
2. Ensure you pass --versions to mega-du, so that you get the size including old versions of files

mega-du --versions

Thanks for the answer, but.... what is the right value that I should take as "used space" when calculating the remaining free space? Please look at this:
$ mega-du --versions
FILENAME SIZE S.WITH VERS
/: 20304533872 20309471541

---

Total storage used: 20304533872 20309471541
$
$ mega-df
Cloud drive: 20309471541 in 2243 file(s) and 233 folder(s)
Inbox: 0 in 0 file(s) and 0 folder(s)
Rubbish bin: 741874370 in 60 file(s) and 32 folder(s)
Incoming shares:
Berlino con papi: 1675361732 in 233 file(s) and 4 folder(s)

---

USED STORAGE: 21051345911 39.21% of 53687091200

---

Total size taken up by file versions: 4937669

In this case the remaining free space that I can use is (53687091200 - 20309471541) or (53687091200 - 21051345911)?
