negative numbers in command line mode

[michael.leu]

Hi

I cannot get negative numbers to work in command line mode:

# ./parted -v
parted (GNU parted) 3.1
[...]
# ./parted /dev/cciss/c0d2 mkpart primary 1GiB -1s
/root/parted-3.1/parted/.libs/parted: invalid option -- '1'
Usage: parted [-hlmsv] [-a<align>] [DEVICE [COMMAND [PARAMETERS]]...]
# ./parted /dev/cciss/c0d2 mkpart primary 1GiB '-1s'
/root/parted-3.1/parted/.libs/parted: invalid option -- '1'
Usage: parted [-hlmsv] [-a<align>] [DEVICE [COMMAND [PARAMETERS]]...]
# ./parted /dev/cciss/c0d2 mkpart primary 1GiB \-1s
/root/parted-3.1/parted/.libs/parted: invalid option -- '1'
Usage: parted [-hlmsv] [-a<align>] [DEVICE [COMMAND [PARAMETERS]]...]
# ./parted /dev/cciss/c0d2 mkpart primary 1GiB --1s
/root/parted-3.1/parted/.libs/parted: unrecognized option '--1s'
Usage: parted [-hlmsv] [-a<align>] [DEVICE [COMMAND [PARAMETERS]]...] 
# ./parted /dev/cciss/c0d2 mkpart primary 1GiB
End? -1s
-1s
Information: You may need to update /etc/fstab.

Any idea what I'm doing wrong? Or may I hereby report this as a a bug? ;)

Thanks,
Michael
