input directories
Code:

p1( 12 - 14 )
p4( 18  - 21 )
p1( 16 - 18 )
p2( 14  - 18 )
p1( 20 - 22 )
p1( 10 - 12 )
p3( 17  - 19 )
p2( 7.30 - 8 )
p4 ( 6.30 - 7.30 )
.

output directories
Code:
p8( 18.20 - 18.50 )
p1( 11.50 - 13.50 )
p4( 17.50  - 20.50 )
p1( 15.50 - 17.50 )
p2( 13.50  - 17.50 )
p1( 19.50 - 21.50 )
p1( 9.50 - 11.50 )
p3( 16.50  - 18.50 )
p2( 7.20 - 7.50 )
p4 ( 6.20 - 7.20 )
.

i wrote a simple code but i dont know how to expand that for this work

for example to change all 18 to 17.50

Code:
find . -type d  | while  read FILE
do
echo "$FILE" | grep 18 | sed 's/18/17.50/g'
done

and so on but my code does not make sense because 18 should be a counter from 1 to 23 and every time change in grep and sed to rename all directories .

any idea ????

RAKE(1) 						 Ruby Programmers Reference Guide						   RAKE(1)

NAME
rake -- Ruby Make SYNOPSIS
rake [--f Rakefile] [--version] [-CGNPgnqstv] [-D [PATTERN]] [-E CODE] [-I LIBDIR] [-R RAKELIBDIR] [-T [PATTERN]] [-e CODE] [-p CODE] [-r MODULE] [--rules] [variable=value] target ... DESCRIPTION
Rake is a simple ruby(1) build program with capabilities similar to the regular make(1) command. Rake has the following features: o Rakefiles (Rake's version of Makefiles) are completely defined in standard Ruby syntax. No XML files to edit. No quirky Makefile syntax to worry about (is that a tab or a space?). o Users can specify tasks with prerequisites. o Rake supports rule patterns to synthesize implicit tasks. o Flexible FileLists that act like arrays but know about manipulating file names and paths. o A library of prepackaged tasks to make building rakefiles easier. OPTIONS
--version Display the program version. -C --classic-namespace Put Task and FileTask in the top level namespace -D [PATTERN] --describe [PATTERN] Describe the tasks (matching optional PATTERN), then exit. -E CODE --execute-continue CODE Execute some Ruby code, then continue with normal task processing. -G --no-system --nosystem Use standard project Rakefile search paths, ignore system wide rakefiles. -I LIBDIR --libdir LIBDIR Include LIBDIR in the search path for required modules. -N --no-search --nosearch Do not search parent directories for the Rakefile. -P --prereqs Display the tasks and dependencies, then exit. -R RAKELIBDIR --rakelib RAKELIBDIR --rakelibdir RAKELIBDIR Auto-import any .rake files in RAKELIBDIR. (default is rakelib ) -T [PATTERN] --tasks [PATTERN] Display the tasks (matching optional PATTERN) with descriptions, then exit. -e CODE --execute CODE Execute some Ruby code and exit. -f FILE --rakefile FILE Use FILE as the rakefile. -h --help Prints a summary of options. -g --system Using system wide (global) rakefiles (usually ~/.rake/*.rake ). -n --dry-run Do a dry run without executing actions. -p CODE --execute-print CODE Execute some Ruby code, print the result, then exit. -q --quiet Do not log messages to standard output. -r MODULE --require MODULE Require MODULE before executing rakefile. -s --silent Like --quiet, but also suppresses the 'in directory' announcement. -t --trace Turn on invoke/execute tracing, enable full backtrace. -v --verbose Log message to standard output (default). --rules Trace the rules resolution.
