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:
head out.txt

For those rows that are separated by ",", I want to keep everything after the first comma and before the second comma.
This is my desired output:

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.
