Put the below code into your bashrc then just :

UZ file.tar

you can also use it with zip, 7z, tar.gz, or gz.

in your bashrc:

UZ() {
  # Extract file name and extension separately
  f_name="$(basename "$1" | awk -F. 'BEGIN{OFS="_"} {if ($(NF-1) == "tar") {ext = $(NF-1) "." $NF; NF-=2} else {ext = $NF; NF--}; print $0}')"
  f_ext="$(echo "$1" | awk -F. '{if ($(NF-1) == "tar") {print $(NF-1) "." $NF} else {print $NF}}')"

  # Determine the last or last two dots to perform the actions
  case "$f_ext" in
    "zip")
      echo "unzipping zip to $f_name"
      mkdir "$f_name"
      unzip "$1" -d "$f_name"
      ;;
    "tar.gz" | "tgz")
      echo "unzipping tar.gz to $f_name"
      mkdir "$f_name"
      tar -zxvf "$1" -C "$f_name" --strip-components 1
      ;;
    "tar")
      echo "unzipping tar to $f_name"
      mkdir "$f_name"
      tar -xvf "$1" -C "$f_name"
      ;;
    "gz")
      echo "unzipping gz to $f_name"
      mkdir "$f_name"
      gunzip -c "$1" > "$f_name"
      ;;
    "7z")
      echo "unzipping 7z to $f_name"
      mkdir "$f_name"
      7z x "$1" -o"$f_name"
      ;;
    *)
      echo "unknown file type: $f_ext"
      ;;
  esac
}

You are running tar xzvf, which extracts a compressed tar, but the filename given is tar, which is just a tar file, not compressed. Try without the z.

tar xvf ...
