Something similar to "du -sh'

amit mehta_2 — Tue, 16 Jan 2007 06:37:45 GMT

Hi,

On a linux machine:
$ du -sh ./
405M ./

Above gives disk usage in human readable format in Linux.
Do we have anything similar in HP-UX ?

Hi,

# du -ks
Calculates the block count in 1024-byte (kilobytes) units rather than the default 512-byte units.

I am afraid,
HP-UX isn't "human readable",
at least in this respect.
You would have to increase readbility by yourself, like e.g.

$ du -skx /opt|awk '{print$1/2^10}'
3094.95

Or you can use the attached script. It will summarize each directory in Gb, Mb, Kb, etc. Adjust the code as needed.

Hi Ralph,

i tried it on my linux machine.

405M ./ <--------
$ du -skx ./|awk '{print$1/2 ^10}'

also works is:

find -type f | du -sk
or
find -type f -prune | du -sk

amit,

probably some rounding or kibi vs. kilo issue?

I went on one of our RHFC3 linux boxes.
Oops, have you seen this?

# du -sH /usr
du: WARNING: use --si, not -H; the meaning of the -H option will soon
change to be the same as that of --dereference-args (-D)
824M /usr

If I look up the Warning about deprecated -H switch in the manpage of *my* version of du,
this indeed seems to relate to the notoriuos kibi vs. kilo issue.

excerpt from man du:

-H like --si, but also evokes a warning; will soon change to be
equivalent to --dereference-args (-D)

--si like -h, but use powers of 1000 not 1024

Well, I guess for "humans" it is considered too confusing to calculate in powers of base 2 rather than 10.
On the other hand I suspect this has been inculcated by HW vendors who can better bost with higher capacity figures of their storage devices.

Hi,

a little modification of Ralf's commandline to get a more linux-like output:

du -skx /opt|awk '{printf("%dM %s\n",$1/2^10,$2)}'
