Do you want to append them to the last column, or do you want to add them as new columns at the end of each line? What dates do you want to add? Do you want multiple dates on each line or just a single date per line?

@Kusalananda new columns at the end of each line.. because thats what a column is. Otherwise it'd be a row.

@jdwolf No. There's a difference between changing1,2,3into1,2,3-20180529("adding a date to the last column") and changing it into1,2,3,20180529("adding a new column with a date"). I asked since the interpretation of "adding dates in the last column" is clearly ambiguous. Also "adding dates" could mean adding multiple dates to each record. It's unclear what is meant, and what dates should be added (today's date, or depending on some files' timestamp, or depending on some other data in the file, or incrementing by one day throughout the file starting at some particular date).

@Kusalananda Agreed on all your points pretty much. I just like how you've worded it now is much clearly on what the OP needs to specify~ ty.

Simply use sed:
sed "s/$/,$(date)/" infile.csv
With formatting:
sed "s/$/,$(date +'%F %T')/" infile
- the
$ins/$/.../is pointing anchor to the end of line. - we used double-quotes to expand the command-substitution
$(...)output. - this adds date as a new column. remove comma
,before,$(...)to append to the last column. use
-ioption of sed to in-place change in file itself or take a backup in addition:sed -i.bak "s/$/,$(date +'%F %T')/" infile
see for more formatting options in man date under "FORMAT controls" section.
