qemu-img:tldr:b484c
The command qemu-img create ${image_name-img} ${gigabytes}G
is used to create a disk image file with a specific size using the qemu-img
command-line tool.
Here is a breakdown of the command:
-
qemu-img
: This is the command-line tool used to manipulate disk images for the QEMU virtualization software. -
create
: This is the subcommand ofqemu-img
used to create a new disk image. -
${image_name-img}
: This is a placeholder for the name of the disk image file you want to create. You need to replace${image_name-img}
with the actual name you want to assign to the image file. For example, if you want to name the image file asmyimage
, you would replace${image_name-img}
withmyimage
. -
${gigabytes}
: This is a placeholder for the size of the disk image you want to create, specified in gigabytes (GB). You need to replace${gigabytes}
with the desired size for the image. For example, if you want to create a 10GB disk image, you would replace${gigabytes}
with10
. -
G
: This is a suffix used to specify that the size is in gigabytes. So, if you specify10
followed byG
, it means 10 gigabytes.
By executing this command with the appropriate values filled in, you would create a new disk image file with the specified name and size. The file would be ready for use in virtualization environments, such as QEMU.
