Thank you

I can think of 3 different ways to interpret that requirement.

Post input and expected output so we don't have to guess. Smilie

Ah, I see. 'join' confused me, I thought you were wanting longer lines instead of more lines.

Code:
FIRST=

for FILE in *.csv
do
        exec 5<"$FILE" # Open file
        read LINE <&5 # Read first line
        [ -z "$FIRST" ] && echo "$LINE" # Print it only from first file
        FIRST="no"

        cat <&5 # Print the rest directly to standard output
        exec 5<&- # Close file
        # Redirect stdout for this section into file.out
done > file.out
