I want to take a file that has a series of "#" commented lines then tab delimited content.  What I would like to do is use regular expression and perl to input the datafile and output only the USGS line in csv format with no blank lines.  I fount a nice regex that changes the file to csv but having issues isolating that single USGS line.  Thank you!

perl -lpe 's/"/""/g; s/^|$/"/g; s/\t/","/g' < getme.txt > output.csv

Example content :
*full datafile attached

#    DD parameter   Description
#    01   00060     Discharge, cubic feet per second
#    02   00065     Gage height, feet
#
# Data-value qualification codes included in this output:
#     P  Provisional data subject to revision.
#
      agency_cd   site_no datetime    tz_cd   01_00060    01_00060_cd 02_00065    02_00065_cd
     5s  15s 20d 6s  14n 10s 14n 10s
      USGS    01417000    2013-04-06 09:45    EST 80  P   2.95    P
