Setup CLI Usage on SharkLinux

pCloud

pCloud offers two CLI clients: pcloudcc (daemon) and pcloudcmd (interactive). Installation via Snap or Debian package:

sudo apt update
sudo apt install snapd
sudo snap install pcloud
# or using .deb
wget https://download.pcloud.com/pcloudcc/pcloudcc_x86_64.deb
sudo dpkg -i pcloudcc_x86_64.deb

Authenticate and mount your drive:

pcloudcc --remote-name SharkCloud --install-service
pcloudcc --login
# To sync:
pcloudcmd sync upload /home/user/documents /documents

Common issues: Incorrect permissions for FUSE mount—run sudo usermod -aG fuse USER and re-login.

MEGA (megacmd)

MEGA Command Line delivers mega-login, mega-put, mega-get:

sudo apt update
sudo apt install gnupg2 dirmngr
# add repository
wget -qO - https://mega.nz/keys/MEGA_signing.key  sudo apt-key add -
sudo sh -c echo deb https://mega.nz/linux/repo/Ubuntu_(lsb_release -sr)_amd64/ ./ > /etc/apt/sources.list.d/mega.list
sudo apt update
sudo apt install megacmd

mega-login user@example.com P@ssw0rd
mega-mkdir /Root/Backups
mega-put ~/backup.tar.gz /Root/Backups/backup.tar.gz

Common issues: IPv6 DNS resolution may fail disable IPv6 or force IPv4 by prefixing mega-login --no-ssl-verify.

Proton Drive (community CLI)

Proton Drive lacks an official CLI you can use proton-drive-cli:

sudo apt update
sudo apt install python3-pip
pip3 install proton-drive-cli

proton-drive-cli login
proton-drive-cli upload ./report.pdf /MyDrive/report.pdf
proton-drive-cli download /MyDrive/photo.jpg ./photo.jpg

Common issues: 2FA login failures—use proton-drive-cli login --twofactor YOUR_CODE.

Filen

Filen provides a Python-based CLI:

sudo apt update
sudo apt install python3-pip
pip3 install filen-cli

filen auth login
filen upload file.txt /MyFilen/
filen download /MyFilen/file.txt .

Common issues: API timeout on large files—use --chunk-size flag to adjust.

Tresorit (via rclone/WebDAV)

Tresorit’s CLI is not official, but you can mount via WebDAV or use rclone:

sudo apt update
sudo apt install rclone davfs2
# Configure rclone
rclone config
# Create new remote tresorit -> vendor “webdav” -> url https://webdav.tresorit.com

rclone ls tresorit:
rclone copy ~/files tresorit:BackupFolder
# Or mount with davfs2
sudo mkdir /mnt/tresorit
sudo mount -t davfs https://webdav.tresorit.com /mnt/tresorit

Common issues: SSL cert errors—install ca-certificates and add Tresorit’s root CA.

Icedrive

Icedrive provides an official CLI in beta as AppImage:

wget https://download.icedrive.net/linux/icedrive-cli.AppImage
chmod  x icedrive-cli.AppImage
./icedrive-cli.AppImage login

./icedrive-cli.AppImage upload docs/ /MyDrive/docs/
./icedrive-cli.AppImage download /MyDrive/photo.png ./photo.png

Common issues: AppImage missing FUSE support—install fuse and run sudo modprobe fuse.

Backblaze B2

The official b2 CLI uses Python rclone also supports B2:

sudo apt update
sudo apt install python3-pip
pip3 install b2
b2 authorize-account yourAccountId yourApplicationKey

b2 create-bucket my-bucket allPrivate
b2 upload-file my-bucket bigfile.iso bigfile.iso
# Using rclone
rclone config
# choose b2, set account  key
rclone copy ~/video b2:my-bucket/videos

Common issues: “Timeout” on large uploads—adjust B2_MAX_UPLOAD_RETRIES env var or use multipart via rclone.

Common Problems Troubleshooting

• FUSE permissions: Always add your user to the fuse group (sudo usermod -aG fuse USER).
• Missing dependencies: Many CLIs need libssl-dev, curl or ca-certificates.
• 2FA and API quotas: Check provider documentation for token-based login or multi-factor flags.
• SSL/TLS errors: Install and update system certificates verify OpenSSL version.
• Rate limiting: Slow down concurrency or use exponential back-off flags (--bwlimit, --transfers in rclone).

Conclusion

SharkLinux’s Debian foundation ensures compatibility with most Linux CLIs. Choose pCloud or MEGA for solid official tools, Proton Drive or Tresorit for supreme privacy, Filen or Icedrive for balanced features, and Backblaze B2 for cost-effective large-scale backups. Armed with this guide, you can automate your backups, synchronize folders, and integrate cloud storage into your daily Linux workflows via shell scripting and cron jobs.
