Warning: This specific example does not appear to have any embedded commas in the first field. For example, in"blah, blah",content:n ..., the comma inside the double-quotes is not a field separator. If someone reads this and has to deal with those, the answer provided here will not work correctly. Parsing CSV correctly to deal with such non-separating commas is tricky business.

With sed and to remove the lines that second field contains content, you could do:
sed '/^[^,]*,[^,]*content/d' infile
or to remove the lines which second field stars with content:
sed '/^[^,]*,content/d' infile

awk -F, '$2 !~ /content/' file.csv
If you mean "remove lines where the 2nd field starts with "content", then
awk -F, '$2 !~ /^content/' file.csv

basically what you can do in the easiest way is:
cat "/dir/yourfile.csv" | grep -v ",content:" > newcsvfile.csv
if you want to use the same file name then you can do:
cat "/dir/yourfile.csv" | grep -v ",content:" > tmpfile && mv tmpfile "/dir/yourfile.csv"

What does this do if "content" is in the third position of a line?
– Christian Gibbons
Sep 13 at 18:07
that's an assumption if "content:" word will be only in the 2nd field, if it is in different field then the solution would not work and would be different
