How to unzip a file on a remote server?

Question

bash

I am writing a script that sends an archive with databases to the server, and unpacks it there. But I can not correctly write the unpacking.

tar -zcvf ./$fileName $dbsDir
scp ./$fileName [email protected]$server:/home

# Не работает. Просто пример
ssh [email protected]$server 'cd /home && tar xvf $fileName'

Answer 1

Both implementations work:

ssh [email protected]$server << ENDSSH
cd /home && tar xvf $fileName
ENDSSH

ssh [email protected]$server << ENDSSH
tar xvf /home/$fileName -C /home
ENDSSH
