The command dd if=${filename-iso} of=/dev/${usb_drive}
is used to create a bootable USB drive by writing the contents of an ISO image file to the USB drive.
Here's how the command works:
-
dd
is a Unix command used for converting and copying files. It stands for "data description" and is commonly used for low-level operations like creating bootable media. -
if=${filename-iso}
specifies the input file, in this case, the ISO image file that you want to write to the USB drive.${filename-iso}
represents the variable name for the ISO file. -
of=/dev/${usb_drive}
specifies the output file, which is the USB drive you want to write the ISO image to./dev/${usb_drive}
represents the variable name for the USB drive.
By running this command and replacing the ${filename-iso}
and ${usb_drive}
variables with appropriate values, you can create a bootable USB drive containing the contents of the ISO image file.
