Shell Programming and Scripting

I have been trying this a lot of different ways and haven't found too much online. Here's what I've got so far:

Code:

j=0 
declare -a first 
zero=(`cat $tmpfile`)          
      
     for i in "${zero[@]}"         
     do                 
           command $i >> "${first[$j]}"                 
           (( j = j + 1 ))                 
           sleep 2                  

     done < $tmpfile

Basically $i would just be a parameter for the command taken from a temp file. The command would output many single column lines of text that I would like to store line by line in the array elements of first[*] (or $j). While I've found tons on storing to a file and then to an array, I want to start skipping the temp files and just putting output in the arrays. Is this possible in Bash?

Thank you Cfajohnson! That does work, however it no longer outputs line by line from my program. Is there a trick to creating a new line after each element?

I have Bash version 4.1.5 and there seems to be no man page for that on my system. I will try to research this though.

Hi.

You can find a bash4 man page here

Oh! I thought mapfile had its own man page. I see now.

Thank you Scottn

I got the problem with newlines too. Didn't think it would be that simple:

Code:

a=0
length=${#first[@]}
for (( b = 0; b < $length; b++ ));
do
        echo -e "${first[$a]}\n" 
done

Thanks again!
