regex - Skip lines whose 2nd column has a string -

-

my cvs file has 10 columns , want rid of lines 2nd field ($2) has string beginning "synonymous". tried this:

awk '$2 ~ /^synonymous/ {next}'

but not print out anything.

you need tell awk want do. far you've told skip records 2nd field starts "synonymous" haven't told awk @ rest of them. try instead:

awk '$2 !~ /^synonymous/'

that says "if 2nd field doesn't start synonymous, invoke default action of printing record".
