What difference does it make to the program being run whether a comma is in quotes?
Code:
$ echo ,

,

$ echo ","

,

$

echo doesn't see the quotes. Neither does awk.
Quote:
nawk -F, '{$8=substr($8,1+index($8,"_")) OFS $8}1' OFS=, phi_pep.txt > phiPep.txt ?
Sure, as long as the file you're writing and the file you're reading aren't the same.
