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"
I've always found this site useful when fiddling with shell scripts: http://tldp.org/LDP/abs/html/
you'll have to get your output into an array using some sort of string manipulation using the spaces as delimiters, then loop over that to build some html output - so the return value will basically just output your select box on the page where you execute your cgi/bash script.
