從命令行使用 p7zip 壓縮文件

我想使用 7z 將四個 ISO 文件壓縮到一個ISOs.7z從我的 Sabayon 機器上的命令行呼叫的新存檔中。這些是我到目前為止嘗試過的命令（我知道這些都沒有指定輸出 7z 存檔的名稱，只是從這些命令開始簡單，以便我可以使用 7z 進行壓縮）：

7z a chakra-2015.11-fermi-x86_64.iso openSUSE-Leap-42.1-DVD-x86_64.iso PCBSD10.2-RELEASE-08-19-2015-x64-DVD-USB.iso Sabayon_Linux_15.11_amd64_MATE.iso

和

7za a chakra-2015.11-fermi-x86_64.iso openSUSE-Leap-42.1-DVD-x86_64.iso PCBSD10.2-RELEASE-08-19-2015-x64-DVD-USB.iso Sabayon_Linux_15.11_amd64_MATE.iso

都沒有工作。後者給出：

Open archive: chakra-2015.11-fermi-x86_64.iso

ERRORS:
There are data after the end of archive

--
Path = chakra-2015.11-fermi-x86_64.iso

E_NOTIMPL


System ERROR:

正確的語法是：

7z a isos.7z *.iso

或者

7z a isos.7z chakra-2015.11-fermi-x86_64.iso openSUSE-Leap-42.1-DVD-x86_64.iso PCBSD10.2-RELEASE-08-19-2015-x64-DVD-USB.iso Sabayon_Linux_15.11_amd64_MATE.iso
