I have a huge CSV file which contains 100000 rows. However, I need to do some processing and so for that I need to have a single space before the first comma. My current data is something like below.
I need a space before the first comma for some internal processing. So, after the command execution, I need the file to be like below.
I tried the gawk command to get the first column alone using $1. However, $1 gives me the entire row. Is there another way to do the above task?
