I don't want to use NIS/LDAP solution just a simple shell script utilitarian methodoloy would suffice. Also, I am... (1 Reply)
Hi,
How do you actually create a unique ID on a distributed system. I looked at gethostid but the man page says that its not guaranteed to be unique. Also using the IP address does not seem to be a feasible solution. Is there a function call or mechanism by which this is possible when even the... (4 Replies)

Hi,
I have below code for disk creation

So what my understanding is first it is checking the disk under /dev sdb,sdc,sdd,...sdz whether 25 disk are existing
if not then its creating the 25 physical volume.

EMPTY-PAGE(1) ExactImage Manual EMPTY-PAGE(1)NAME
empty-page - empty page detector of the ExactImage toolkit
SYNOPSIS
empty-page [option...] {-i | --input} input-file
empty-page {-h | --help}
DESCRIPTION
ExactImage is a fast C++ image processing library. Unlike many other library frameworks it allows operation in several color spaces and bit
depths natively, resulting in low memory and computational requirements.
empty-page counts dark pixels of a black and white image and decides with a threshold whether the page is most probably empty, and thus can
be removed from the image processing stream.
OPTIONS -i file, --input file
Read image from the specified file.
-m n, --margin n
Set width of border margin to skip. For speed reasons, the margin has to be a multiple of 8. The default is 16.
-p x, --percentage x
Set fraction of permissible dark pixels. The default is 0.05 (5%).
-h, --help
Display help text and exit.
EXAMPLES
$ empty-page -i test.tif
The image has 75461 dark pixels from a total of 1060992 (7.11231%).
non-empty
EXIT STATUS
The exit status is 0 if the image is mostly white, 1 otherwise.
