Print to dynamic files from AWK cmd

To print the output of AWK to a dynamic file:

head  236_236_raw |  awk -F';' '{  print $7,"\t",$6 > ("_"$2"_"$3".txt")}'

If the number of files open are large, you will get the following error:

awk: * makes too many open files

 input record number 203, file

 source line number 1

To overcome the above problem, you can close the files like this:

head  236_236_raw |  awk -F';' '{  print $7,"\t",$6 >> ("_"$2"_"$3".txt"); close("_"$2"_"$3".txt")}'

The important point to note is that now we changed the redirection operator to ">>" from ">". Makes sense ? :)
