BASH: Each line of multiple text files gets added to one line
 
I currently have 3 files with floating point data that I wish to have in a single file with the format:

Code:
F1      F1    F3          Output

a1      b1    c1          a1 b1 c1
a2      b2    c2          a2 b2 c2
a3      b3    c3          a3 b3 c3
a4      b4    c4          a4 b4 c4
I would greatly appreciate any intuition on how to go about this.

Thank you in advance!

Code:
#!/bin/bash

{
    while read -u 3 A && read -u 4 B && read -u 5 C; do
        echo "$A $B $C"
    done
} 3<"$1" 4<"$2" 5<"$3"
save it to script.sh then run

Code:
bash script.sh F1 F2 F3 > OUTPUT
