Output variable side by side
how do you display variable that contain multi line side by side dynamically without knowing the number of variable and line for each variable ?

Example
echo $a
Code:
a
b
c

echo $b
Code:
1
2
3

echo $c
Code:
q
w
e

how to output the result in
Code:
a 1 q
b 2 w
c 3 e

If you have a recent bash, try
Code:
paste <(echo "$a") <(echo "$b") <(echo "$c")
a    1    q
b    2    w
c    3    e

If the above posted solution is not working then create three temp file and pass it to the paste command.
Code:
$echo "$a" > t1
$ echo "$b" > t2
$ echo "$c" > t3
$ paste t1 t2 t3
a       1       p
b       2       q
c       3       r
