We used FORCE using Docker (FORCE v. 3.7.10) to work on a "prebuilt image" which can be "easily" pulled on a linux based system. We used Ubuntu 22.04.3 LTS for our processing.
Prior to downloading data we made sure of sufficient storage for mass processing of the data heavy satellite images.

Please exchange and adjust everything to your specific system and filenames depending of you are using Docker or not.

# 1. set up the working environment
#####################################

cd /home/myproject

#create all kind of needed directories
mkdir -p level1/level1-datapool/Landsat
mkdir -p level1/meta/
mkdir level2
mkdir catalog
mkdir param
mkdir log
mkdir misc
mkdir temp
mkdir level2/base
mkdir provenance

# Download metadata catalouge once before first use
force-level1-csd -u catalog/

## prior to data download either
a. Save the study area shapefile in misc directory
or b. select the tilenames (for Sentinel-2) and path/row numbers (for Landsat)

#####################################################
# 2. Download level 1 Sentinel2 and Landsat data
#####################################################

#2.1 download sentinel 2 data for 2017 to 2021 using study area shapefile
# Note: First Docker command needs to use the Docker creditentials
sudo docker run -v /home/myproject:/opt/data --user "$yourusername" --env FORCE_CREDENTIALS=/app/credentials -v $HOME:/app/credentials davidfrantz/force force-level1-csd -c 0,75 -d 20170101,20211231 -s S2A,S2B /opt/data/catalog/ /opt/data/level1/level1-datapool/ /opt/data/level1/level1-datapool/queue.txt /opt/data/misc/mystudyarea_shapefile.shp

#2.2 download landsat data using landsatlinks
## --> make an account and request permission to download e.g. get "machine to machine" API
## create a file with your user credetials
## a simple .txt file first row username, second row password ### think of special character readability
## save the study area shapefile in the misc directory

# 2.2.1 create file with download links for Landsat using landsatlinks:
landsatlinks search /home/myproject/misc/mystudyarea_shapefile.shp /home/myproject/misc -s OLI -d 20220101,20221231 -m 1,2,3,4,5,6,7,8,9,10,11,12 -c 0,75 --secret /home/myproject/misc/landsatlink.txt -q /home/myproject/misc/landsat_download_links.txt

-d = daterange
-m = month
-s = sensor
-c = cloud cover
-q = queue file
--secret = path to the login credentials (Earth Explorer login)

Reference to the landsatlinks github repository:  https://github.com/ernstste/landsatlinks

#2.2.2 In the misc folder access the download URLS written as a .txt file:
cat /home/myproject/misc/urls_landsat_OLI_20230130T143754.txt| xargs -n 1 -P 50 wget -q -P /home/myproject/level1/level1-datapool/Landsat/landsatlinks --content-disposition
ATTENTION: Please note, that the TXT file needs to be exchange for your project related file. This is just an example file mentioned here!

#2.2.3 Unzip all the downloaded .tar files in the respective landsatlinks folder:

cd /home/myproject/level1/level1-datapool/Landsat/landsatlinks
for f in *.tar; do 
y=${f%.tar} 
mkdir $y 
sudo tar -xf "$f" -C $y; done
