I am working on a qnx node where one of my hard disk is showing to be quite full, when I use command df.
Please let me know what are specific command to see the usage of space on this disk. I am not able to get these details using du.
Even df is showing device to be 765 ful but still it shows only 1440 KB of used space.
I am confused. Please help. |

1440 = how many blocks physically present on the disk
1438 = how many blocks physically present on the disk available for user ( 2 blocks are used by file system )
1093 = used blocks
344 = free blocks
76% = 1093 used blocks out of 1440
It all checks out ok AFAICT. |

I understand:
76% = 1093 used blocks out of 1440
But my problem is I want to know what all directories and files are contributing to this 76% so that I can plan to take back up and remove unwanted stuff.
When I try du the space consumed by directoires in this path is very less.
Please guide.
Thanks and Regards

du is saying there is 2187 block used which if you divide by 2 gives you 1093, a clue dear Watson.
du is giving number in block of 512 bytes ( 512*2187 ) = 1119744 While df give number in 1K 1024*1093 = 1119232. |
