Hi,

I am using SCO UNIX version 6.0.0 release 5. I am using du and df space to see the used space in the / partition. I am using du -k option to get count in 1024 k so that it directly makes kb. In dfspace I subtracted the used mb from total size mb which should be the used space and then convert to GB. But the output from du -k (converted to gb ) donot match this output of dfspace (converted to gb)

Here it goes :

> du -k  =  38339676 (kb) = 38.3 gb
 
> dfspace 
 
788718.80 MB of 851248.99 MB available

Hi,

< http://www.unix.com/unix-dummies-que...isk-space.html >

The links explains that df will use the block size to give the usage details. My system block size is 1024bytes and for that the outputs are not matching. I already know that block size is something which affects the usage reported, but my question was after implementing that logic. I used DU with block size of 1024 and df space is also using 1024 b block size (or let me know how to check df's used block size)

My query still remains...

regards,

Dexter

And BTW, I talked about "dfspace" and not "df". Reporting by dfspace is in MB . I donot know the underlying princile of how it reports the usage.

You should post both

du -k

df -k

dfspace

On my partition /

du -k | tail -1 gives

38253272 (last line is the summantion )

df -k -v gives

/          /dev/root            871678974  63965476 807713498     8%

From the man page for du. (SCO 6.0.0)

@dextergenious: again, is this discrepancy still there after a reboot ?

Is your file system clean ? (fsck)
