Question Recursively hard linking files -- bonehead question
I used to program ksh a while back, but I've been off in Oracle/Windows land (for clients -- not by choice) for so long that I can't remember what should be an easy thing. Here's the scenario:

1)Find all files and directories beneath some directory point (A).
2)If directory, make the subdirectory at some different directory point (B)
3)If file, link (not symbolic) the file in the correct subdirectory under point B.

For a more concrete example, here's a scenario.

Point A: /usr/test
Point B: /var/test

File structures:
/usr/test
/usr/test/oracle
/usr/test/oracle/script 1
/usr/test/oracle/script 2
/usr/test/db2
/usr/test/db2/script 1
/usr/test/db2/script 2

I'm trying to write a script that will result in the following output (and/or actually do the work instead of writing an output script, but I can live with creating a secondary script):

mkdir /var/test/oracle
ln /usr/test/oracle/"script 1" /var/test/oracle/"script 1"
ln /usr/test/oracle/"script 2" /var/test/oracle/"script 2"
mkdir /var/test/db2
ln /usr/test/db2/"script 1" /var/test/db2/"script 1"
ln /usr/test/db2/"script 2" /var/test/db2/"script 2"

Here's the pseudo code for what I've been working on so far:

#!/bin/bash

#declare variables
cnt=0 #array counter
# &1 == Source Directory
# &2 == Target Directory
source_len=awk '{ print length }'

# Find out what the subdirectories are
full_list=find $1 -print 2>/dev/null

## Populate the subdirectories into an array
## Trim the root from the subdirectories into a second array
subdir = full_list| cut -c source_len-

# Loop through, creating them one at a time.
if [-d full_list]
then
# make the new directory
echo "mkdir $target/$subdir"
elif [-f source]
then
# link the file
echo "ln $full_list $target/$subdir"
fi

Someone suggested to me mounting /usr/test to /var/test, but that doesn't completely satisfy the necessary requirements (and would result in a few thousand mount points being scattered through the environment -- not a pretty picture)...

if this was PL/SQL, it would have taken me about 15 seconds to write, but I'm rusty on bash scripting. Any thoughts?

fntsample

fntsample(1)						      General Commands Manual						      fntsample(1)

NAME

       fntsample - PDF and PostScript font samples generator

SYNOPSIS

       fntsample [ OPTIONS ] -f FONT-FILE -o OUTPUT-FILE
       fntsample -h

DESCRIPTION

       fntsample  program  can	be  used  to generate font samples that show Unicode coverage of the font and are similar in appearance to Unicode
       charts. Samples can be saved into PDF (default) or PostScript file.

OPTIONS

       fntsample supports the following options.

       --font-file, -f FONT-FILE
	      Make samples of FONT-FILE.

       --font-index, -n IDX
	      Font index for FONT-FILE specified using --font-file option.  Useful for files that contain multiple fonts,  like  TrueType  Collec-
	      tions (.ttc).  By default font with index 0 is used.

       --output-file, -o OUTPUT-FILE
	      Write output to OUTPUT-FILE.

       --other-font-file, -d OTHER-FONT
	      Compare FONT-FILE with OTHER-FONT.  Glyphs added to FONT-FILE will be highlighted.

       --other-index, -m IDX
	      Font index for OTHER-FONT specified using --other-font-file option.

       --postscript-output, -s
	      Use PostScript format for output instead of PDF.

       --svg, -g
	      Use SVG format for output.  The generated document contains one page.  Use range selection options to specify which.

       --print-outline, -l
	      Print  document  outlines data to standard output.  This data can be used to add outlines (aka bookmarks) to resulting PDF file with
	      pdfoutline program.

       --include-range, -i RANGE
	      Show characters in RANGE.

       --exclude-range, -x RANGE
	      Do not show characters in RANGE.

       --style, -t "STYLE: VAL"
	      Set STYLE to value VAL.  Run fntsample with option --help to see list of styles and default values.

       --help, -h
	      Display help text and exit.

       Parameter RANGE for -i and -x can be given as one integer or a pair of integers delimited by minus sign (-).  Integers can be specified	in
       decimal,  hexadecimal  (0x...) or octal (0...) format.  One integer of a pair can be missing (-N can be used to specify all characters with
       codes less or equal to N, and N- for all characters with codes greather or equal to N).	Multiple -i and -x options can be used.

EXAMPLES

       Make PDF samples for font.ttf and write them to file samples.pdf:
	      fntsample -f font.ttf -o samples.pdf

       Make PDF samples for font.ttf, compare it with oldfont.ttf and highlight new glyphs. Write output to file samples.pdf:
	      fntsample -f font.ttf -d oldfont.ttf -o samples.pdf

       Make PostScript samples for font.ttf and write output to file samples.ps.  Show only glyphs for characters with	codes  less  or  equal	to
       U+04FF but exclude U+0370-U+03FF:
	      fntsample -f font.ttf -s -o samples.ps -i -0x04FF -x 0x0370-0x03FF

       Make PDF samples for font.ttf and save output to file samples.pdf adding outlines to it:
	      fntsample -f font.ttf -o temp.pdf -l > outlines.txt
	      pdfoutline temp.pdf outlines.txt samples.pdf
