How to untar all .tar.gz with shell-script?

I tried this:

DIR=/path/tar/*.gz

if [ "$(ls -A $DIR 2> /dev/null)" == "" ]; then
  echo "not gz"
else
  tar -zxvf /path/tar/*.gz -C /path/tar
fi

JavaScript
​x
 
DIR=/path/tar/*.gz​if [ "$(ls -A $DIR 2> /dev/null)" == "" ]; then  echo "not gz"else  tar -zxvf /path/tar/*.gz -C /path/tarfi​

If the folder has one tar, it works. If the folder has many tar, I get an error.

How can I do this?

I have an idea to run a loop to untar, but I don’t know how to solve this problem
