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
