Not only is ls unnecessary, it will break the script if any filenames contain spaces or other pathological characters. Use the wildcard directly:

Code:
for FILE in *.csv

However, if all you want to do is print the names of the files to another file, you don't need a loop:

Code:
printf "%s\n" *.csv > "$LOGFILE"

Or if the file does not have an extension say Rtp200 how to know if it doesn't have an extension

Thanks
