You can use awk to skip fields and create an intermediate file or
better yet, just pipe the output to copy. Here is a trivial example:
awk '{ FS = "\t" ; OFS = "\t" ; print $1,$3 }' inputdatafile
This sets the input and output field separators to tab and outputs the
first and third fields from inputdatafile. If you want to skip the
first record just add the following if statement:
awk '{ FS = "\t" ; OFS = "\t" ; if ( NR > 1 ) print $1,$3 }'
inputdatafile
