Sed and regex help needed
Hi all,

I'm writing a script that replaces a value in a file. The file is formatted as follows:

[param_one] [value]
[param_two] [value]

So, for this example, I'd like to replace the value for param_two. The value for param_two can be a one, or two-digit number. It replaces the value in file.cfg, and directs the output to new_file.cfg. $p2 is a variable passed as an arg on the command line. Here's what I have:

Code:
sed -e "/^\[param_two/s/[0-9]/$p2/" file.cfg > new_file.cfg

This code works like a charm if the value for param_two is a one-digit number and $p2 is a one or two-digit number. If the value is a two-digit number, however, my code only replaces only the first digit; which is not what I want. I want to be able to replace the value with whatever is passed for $p2. Any ideas? Thanks in advance.

pymcabatch

pymcabatch(1)						 PyMca X-Ray Fluorescence Toolkit					     pymcabatch(1)

NAME

       pymcabatch - Batch fitting of X-ray Fluorescence Spectra

SYNOPSIS

       pymcabatch [OPTIONS] [FILES]

DESCRIPTION

       Loops  over a series of input files to which the same fitting parameters can be applied. The setup of the fit configuration is usually made
       via the main PyMca application.

       The program stores the fitted parameters inside the IMAGES directory created in the user specfified output  directory.  The  pymcapostbatch
       tool can perform further analysis via correlation tools.

       The user can also request an HTML report. This is much slower but can be convenient to browse the results with a Web browser.

       This tool is also accessible via the Tools menu of the main PyMca window application.

EXAMPLES

       pymcabatch
	   Open a dialog to select input files, fit configuration, output
	   directory and output parameters.

       pymcabatch --cfg=fitconfig.cfg --outdir=/tmp/ *.mca
	   Fit all the .mca files in current directory using the specified
	   confifuration file fitconfig.cfg and stores the output in /tmp

       pymcabatch --cfg=fitconfig.cfg --outdir=/tmp/ --listfile=inputfiles
	   Same as above but taken the files from the inputfiles file. This file
	   is just a text file with one file path in each line.

CAVEATS

       This  tool,  when  used	in command line mode, could run fully Qt independent because in that case it uses Qt just for showing the progress
       bar.
