Split/create directories on basis of their size
Hi,

I would really apprciate it if someone expert in shell, "shell guru" scripting can help me.

with a shell command how can I create directories and populate on basis of size.
Before I confuse you, let me tell you the scenerio.

We take hot database backup of oracle on disk, and compress/gzip it.
This is done by a shell script which softlinks every last days backup as LATEST (create a soft link to mon,tue,wed,thur,fri,sat,sun whatever is the last day).
As this backup goes into days(moin tue,wed,thur etc) directory. Because the size after compression is more then 250 Gb, netbackup takes ages to back it up.

What I am looking for is, that database backup should be splitted into different directories on basis of size, 25Gb each dir. The script should be able to create directory dir1_1, dir1_2 etc and then put all the *.dbf etc in each directory not more then 25Gb and when it reach the limit it should create another dir, dir1_3 and so on, and copy the file over and so on untill all the *.dbf files in the "last days" dir are copied.
The problem is it should only to dir where symbolic link LATEST points to wether it's monday or tue etc.
So netbackup can back it up in parallel.

Thanks
Amit

platform::shell

platform::shell(n)					       Tcl Bundled Packages						platform::shell(n)

__________________________________________________________________________________________________________________________________________________

NAME

       platform::shell - System identification support code and utilities

SYNOPSIS

       package require platform::shell ?1.1.4?

       platform::shell::generic shell
       platform::shell::identify shell
       platform::shell::platform shell
_________________________________________________________________

DESCRIPTION

       The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.

       This  package  allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
       requirement is that the other shell (identified by its path), is actually executable on the current machine.

       While for most platform this means that the architecture of the interrogated shell is identical to the architecture of  the  running  shell
       this  is  not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
       32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.

       For applications like a code repository it is important to identify the architecture of the shell which will  actually  run  the  installed
       packages, versus the architecture of the shell running the repository software.

COMMANDS

       platform::shell::identify shell
	      This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::generic shell
	      This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::platform shell
	      This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
