Printing Space Between Strings

Question

#!/bin/bash

ARRAY="185.18.207.66 31.18.212.113"

result=""

for i in $ARRAY
do  
    result=$(printf '%s %s' "$result" "$i" "checked")
done

paste <(printf "%s\n" $result)

I am trying to print IP addresses but with appending "checked" phrase for each IP address.

But I can not print a space between IP and "checked" phrase

Above code prints:

185.18.207.66checked
31.18.212.113checked

How can I make it to print like below?

185.18.207.66 checked
31.18.212.113 checked

There are many things to improve with your script before making it done right:

• Missing double quote
• Spawning unnecessary external commands.

Just using an array instead:

#!/bin/bash

ARRAY=(185.18.207.66 31.18.212.113)
printf '%s checked\n' "${ARRAY[@]}"

or using "$@" to make it POSIXly:

#!/bin/sh

set -- 185.18.207.66 31.18.212.113

printf '%s checked\n' "$@"
