Problem with an awk Script
hello,

first, yes i searched the forum , google and read many tutorials but still have a problem with my script.
I have great Problems, because i haven't worked with regular expressions before and never had anything to do with shellscripts. i am a complete Newby in this sort of theme.

I have many Files (end with .per) where RECORD should be renamed in Grid, thats easy with sed but now is the problem not everytime there is Record as text it should be renamed. It should only be renamed when after the RECORD(can be record with only small characters,too) if after the RECORD there is a blank(multiple blanks possible,too) then text(starts with a alphanumeric character but then there can be "_", Numbers in the text) .Following there must be a "[ one or 2 numbers ]".

EDIT:
I forgot to mention, that the the Files are not the same und die column and Row where it stands can differ from File to File, in the same file the searched pattern can exist multiple times. That means the script has to search each file from head to toe.

Examples:
Code:
RECORD s[11]
RECORD s_lt[6]
RECORD sn[9]
RECORD         f1035a[12]

This is the script i have written so far.
Code:
#!/bin/bash

for i in `ls *.per`; do

echo $i
awk '/ *[a-zA-Z]*\[0-9]|[0-9][0-9]\]/ {gsub(/RECORD/,"GRID");}' $i

done

Thank you for your help

SCITOOLS(1)						      General Commands Manual						       SCITOOLS(1)

NAME

       scitools - run a SciTools command

SYNOPSIS

       scitools command [OPTIONS]

DESCRIPTION

       The scitools script takes a command and runs a corresponding utility. The available commands are listed below.

       file2interactive
	      Utility for taking a set of Python statements in a file and creating the corresponding interactive Python shell session.

       floatdiff
	      Script for examining differences in regression tests involving floating-point numbers. Used in [1].

       regression
	      Simple front-end script to SciTools' Regression module. Used in [1].

       ps2mpeg
	      Utility for turning a set of PostScript files into an MPEG movie, using mpeg_encode or ppmtompeg.

       profiler
	      Script for simplifying the execution of Python's profiling tools. Used in [1].

       rename Script for renaming a set of files by substituting one string or regular expression with another.

       subst  Script for subsituting a phrase by another in a set of files. Accepts regular expressions. Treated in [1].

       replace
	      Script  for  subsituting	a  phrase by another in a set of files. Does not use regular expressions, just plain text (well suited for
	      substituting text with much use of backslashes, curly braces, and other special  characters  in  regular	expressions  (e.g.,  LaTeX
	      text).

       movie  Script  for  creating  a	movie file from a sequence of image files (frames). By default an HTML file for displaying the image (PNG)
	      files are made.

       pyreport
	      Processes a Python script and pretty prints the results using LateX. If the script uses show() commands (from scitools.easyviz) they
	      are caught by pyreport and the resulting graphs are inserted in the output pdf. Comments lines starting with "#!" are interpreted as
	      rst lines and pretty printed accordingly in the pdf.
