I met a problem in using grep -P.
There is a text file, temp.txt, whose content is:

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
0.500 0.000
0.750 0.000

2.761 0.178
3.077 0.011
3.251 0.001
3.500 0.000
Which shows the time for the peak amplitude within each measured window.
