Question

I have a CSV file like this:

text,0
more text,2
some more text,100

I need to delete any line containing only 0 in the second column, e.g., the output of the above would be:

more text,2
some more text,100

How can I delete all lines from a CSV with an exact match?

Answer 1

If that’s your last field, grep will do the trick:

grep -v ',0$'

If not, and your fields don’t contain ,, use awk:

awk -F , '{if ($2!='0') print}'

If it’s even more complex use python or ruby with a CSV parser.
