sed - Appending text at EOL not working -


i'm trying append string @ end of each line in file, it's not working. file has format 

1992988282,78.93,sometext

and tried

sed -e 's/$/,2012-09-03/' sample.csv

but text getting appended , replacing characters @ beginning of line. have tried 

awk '{ print $0 ",2012-09-03" }' < sample.csv

and i'm getting exact same problem.

sed -r 's/[[:cntrl:]]*$/,2012-09-03&/' sample.csv

so keep ended control char in place (unless want use without, last & removed)
