making a directory tree:

[Ralph W. Reid]

Here is a little script which might do the trick.


#!/bin/bash
#Create hard links for all files in directories 1, 2, 3, and 4, placing
#those new links in a specified destination directory.
#Include directory names in file names to keep files from overwriting each other.
#IMPORTANT!!! This script assumes that the four directories to be read from
#do not include subdirectories of their own.  If they do, duplicate file
#names _might_be produced.  This is because the slashes in path names
#are simply replaced with hyphens.
#This simple script could use some optimizing for more general use, but
#it should suffice for the specified task.

#define the destination directory
destinationdir=./alldirs

#first, be sure that the '$destinationdir' directory exists
mkdir $destinationdir > /dev/null 2> /dev/null

#create the links
for i in 1/*
do
ln $i $destinationdir/`echo $i | tr '/' '-'`
done
for i in 2/*
do
ln $i $destinationdir/`echo $i | tr '/' '-'`
done
for i in 3/*
do
ln $i $destinationdir/`echo $i | tr '/' '-'`
done
for i in 4/*
do
ln $i $destinationdir/`echo $i | tr '/' '-'`
done


HTH, and have a _great_ weekend!
