Output of command in Bash script to Drop-down box?

Question

First off, I appreciate any and all help in answering this question. I have a command in a bash script that will output the following:

255 254 253 252 ... 7 6 5

Repeating the answer (since the original question was marked as duplicate):

you can write a bash for loop to do everything. This just prints out the elements:

for i in `seq 1 "${#x[*]}"`; do
    echo "|${x[i]} |"
done

To get the alignment correct, you need to figure out the max length (one loop) and then print out the terms:

# w will be the length
w=0
for i in `seq 1 "${#x[*]}"`; do
    if [ $w -lt ${#x[$i]} ]; then w=${#x[$i]}; fi
done
for i in `seq 1 $((w+2))`; do printf "%s" "-"; done
printf "\n"
for i in `seq 1 "${#x[*]}"`; do
    printf "|%-$ws |\n" ${#x[$i]}
done
for i in `seq 1 $((w+2))`; do printf "%s" "-"; done
printf "\n"
