extract characters between two commas?
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ margin-bottom:0;
}
I have a file with ~ 3 million rows, here is the first few lines of my file:

For those rows that are separated by ",", I want to keep everything after the first comma and before the second comma.

awk -F, 'NF > 1 { $1 = $2 } { print $1 }' file
This uses awk to parse the file as lines consisting of comma-delimited fields.
The code detects when there is more than a single field on a line, and when there is, the first field is replaced by the second field. The first field, either unmodified or modified by the conditional code, is then printed.

With a big file, this would probably be faster:awk -F, '{print(NF>1 ? $2 : $1)}'-- since you won't have to rewrite $0

This will print just the first string if there is no comma, second string if there is one or more comma.
