Hi all,
With the following script and parted 3.2
#!/bin/bash
image=blank.img
dd if=/dev/zero of=$image bs=1M count=32
sync
cat <<-EOF | parted -s $image
mklabel msdos
mkpart primary ext2 0 100%
set 1 boot on
EOF
sync
file $image
I see different results if parted is invoked with -s or without.
*With* -s, the call to file results in "blank.img: data" and there's no partitions in the disk image.
*Without* -s,
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) mklabel msdos
(parted) mkpart primary ext2 0 100%
Warning: The resulting partition is not properly aligned for best performance.
(parted) set 1 boot on
(parted) quit
blank.img: DOS/MBR boot sector; partition 1 : ID=0x83, active, start-CHS (0x0,0,2), end-CHS (0x1ff,3,32), startsector 1, 65535 sectors
Removing the quit command makes no difference.
The script without -s will crash at least parted 2.3.
