Strange results from FDISK?????

Hi all,

I am writing script that returns the size of each disk or partition when called. I am using FDISK -l and parsing the results to get the result I want. When I execute fdisk -l it shows correct results, BUT when I execute the same thing with results to be put in a variable, I get strange results:

Quote:
[root@APPSERVER programs]# fdisk -l 2>/dev/null | grep /dev/hda1
/dev/hda1 * 1 2709 20480008+ 7 HPFS/NTFS
Quote:
[root@APPSERVER programs]# result=`fdisk -l 2>/dev/null | grep /dev/hda1`
[root@APPSERVER programs]# echo $result
/dev/hda1 duplicate linux Microsoft Word - This week..pdf partition redundancy week6.pdf windows 1 2709 20480008+ 7 HPFS/NTFS
[root@APPSERVER programs]#
When I want the output to be put in $result variable, fdisk -l returns the files in the folder as well. Another example: When I execute from /:

Quote:
[root@APPSERVER /]# result=`fdisk -l 2>/dev/null | grep /dev/hda1`
[root@APPSERVER /]# echo $result
/dev/hda1 backup backups bin boot dev dhcpcd etc extra home initrd lib lost+found media mnt opt partition proc root sbin srv sys tmp usr var 1 2709 20480008+ 7 HPFS/NTFS
Can anybody tell me why this thing happens? I'm running mandriva 2008.1 by the way.

Thanks

It could be miss but I would assume that asterisk (*) is interpreted in shell. That's why you are receiving list of everything from your path.

Try to 'grep' other partition, some no active.

Did you think about other output from fdisk or other tool like sfdisk ?
