Run the following command to compress an entire directory or a single file on Linux. It’ll also compress every other directory inside a directory you specify–in other words, it works recursively.

tar -czvf name-of-archive.tar.gz /path/to/directory-or-file

Here’s what those switches actually mean:

-c: Create an archive.
-z: Compress the archive with gzip.
-v: Display progress in the terminal while creating the archive, also known as “verbose” mode. The v is always optional in these commands, but it’s helpful.
-f: Allows you to specify the filename of the archive.

scp allows files to be copied to, from, or between different hosts. It uses ssh for data transfer and provides the same authentication and same level of security as ssh.

$ scp your_username@remotehost.edu:FILENAME.txt /some/local/directory

This is a known issue in magento 2.2.4. It can be fixed by modifying the function setForcedArea() in Magento\Email\Model\AbstractTemplate.php

Update

public function setForcedArea($templateId)
 {     if ($this->area) {
         throw new \LogicException(__('Area is already set'));
     }
     $this->area = $this->emailConfig->getTemplateArea($templateId);
     return $this;
 }

To

public function setForcedArea($templateId)
 {     if (!isset($this->area)) {
         $this->area = $this->emailConfig->getTemplateArea($templateId);
     }
     return $this;
 }
