do a calculation for block sice

procfs · 07-07-2006, 03:16 AM

Hi

I want to write a small script to get the block size in Bytes in a file system.

FS=/vol1

du -bs $FS = value assign to FSBY
du -s $FS = value asinine to FSBL

and do

FSBY/FSBY= "one block in bytes"

and assign that value the result to a variable for further processing

Regards

Did you read man bash ?
FSBY=$(du -bs $FS)
FSBL=$(du -s $FS)
echo $((FSBY/FSBL))

This doesn't make man bash (and info bash) less valuable reading for everyone who wants to write useful scripts in Bourne again shell...

Not my topic. Do ask in a separate thread with samba in header.

I did but ????????????????

Maybe nobody now reading is sure that it is impossible - or just nobody tried.. Then ask about good manuals on samba/LDAP and try yourself. I really have only one experience of samba - running smbmount (yes, client only) on FreeBSD 3 years (as I remember) ago...
