Replace all 'low values" in a file
Hi,

I've to replace all low values (hex '00') in a flat file (containing more than 1,000,000 records) with space (hex '20').
I try to use:

Code:
awk '{gsub("\x00","\x20")}' file_name

and I obtain the following response:

Code:
awk: Line AP000010536900577986 cannot have more than 199 fields.
The input line number is 1. The file is file_name.
The source line number is 1.

Can anyone help me?

Thanks in advance.

Stefano

ENVEXT(1)						  The Canonical Csound Reference						 ENVEXT(1)

NAME

       envext - Extracts the envelope of a file to a text file. .

SYNTAX

	   envext [-flags] soundfile

	   csound -U envext [-flags] soundfile

INITIALIZATION

       soundfile - Name of the input soundfile.

       The following flags are available for envext (The default values are stated in parenthesis):
	   -o fnam Name of output filename (newenv)
	   -w size (in seconds) of analysis window (0.25)

       The envext utility generates a text file containing time and amplitude pairs by finding the absolute peak within each window.

EXAMPLE

       Using the command (while in the manual directory):

	   csound -U envext examples/mary.wav

       will produce the a text file containing the following:

	     0.000   0.000
	     0.000   0.000
	     0.250   0.000

	     3.251   0.001
	     3.500   0.000

       Which shows the time for the peak amplitude within each measured window.
