qemu:tldr:08e82

This command starts a QEMU virtual machine using the system architecture of i386 or x86(Intel) and specifies the disk image file to be used as the virtual machine's hard drive.

Here is a breakdown of the command:

• qemu-system-i386: This is the command to start the QEMU virtual machine, specifying the system architecture as i386 or x86 (Intel 32-bit).
• -hda: This option tells QEMU to use the following file as the virtual machine's primary hard disk.
• ${image_name-img}: This is a placeholder for the actual disk image file name. It is enclosed in ${} to indicate it as a variable that needs to be substituted with the real file name. The file name typically has the .img extension.

To use this command, you need to replace ${image_name-img} with the actual disk image file name. For example, if your disk image file is named ubuntu.img, the command would be qemu-system-i386 -hda ubuntu.img.
