Save output into file bash scripting

Use and complete the template provided. The entire template must be completed. If you don't, your post may be deleted!

1. The problem statement, all variables and given/known data:
Hi there.

i have created a program that in the end it will give output like this

Code:

1   2   3   4   5
10  9   8   7   6
11  12  13  14  15
..............  17

i wonder how to save the output into a single string and into a file.
i.e 1 10 11 12 9 2 3 8 13 14 7 4 5 6 15 17 (in this order, its like a snake)

i googled it but i only came across with saving it row by row (1 2 3 4 5 10 9......)

any idea how?

2. Relevant commands, code, scripts, algorithms:

Code:

file4="temp.txt"
name4=$(cat $file4)
echo $name4 |  sed 's/\(.\)/\1\n/g' > file4.txt

echo "enter how many rows :"
read cols

IFS=$'\n' a=($(cat file4.txt))
for j in $(seq ${#a[*]}); do
    [[ ${a[$j-1]} = $name ]] && echo "${a[$i]}"
done

for (( i=0; i<=$(( ${#a[@]} / cols )); ++i )); do
    for (( j=0; j<cols; ++j )); do
        if (( i%2 )); then idx=$(( (i + 1) / 2 * 2 * cols - j - 1 ))
        else idx=$(( (i / 2) * 2 * cols + j )); fi
        printf "%-4s  " "${a[idx]}"
    done
    printf "\n"
done

debconf-mergetemplate

DEBCONF-MERGETEMPLATE(1)					      Debconf						  DEBCONF-MERGETEMPLATE(1)

NAME

       debconf-mergetemplate - merge together multiple debconf template files

SYNOPSIS

	debconf-mergetemplate [options] [templates.ll ...] templates

DESCRIPTION

       Note: This utility is deprecated. You should switch to using po-debconf's po2debconf program.

       This program is useful if you have multiple debconf templates files which you want to merge together into one big file. All the specified
       files will be read in, merged, and output to standard output.

       This can be especially useful if you are dealing with translated template files. In this case, you might have your main template file, plus
       several other files provided by the translators. These files will have translated fields in them, and maybe the translators left in the
       english versions of the fields they translated, for their reference.

       So, you want to merge together all the translated templates files with your main templates file. Any fields that are unique to the
       translated files need to be added in to the correct templates, but any fields they have in common should be superseded by the fields in the
       main file (which might be more up-to-date).

       This program handles that case properly, just list each of the translated templates files, and then your main templates file last.

OPTIONS

       --outdated
	   Merge in even outdated translations. The default is to drop them with a warning message.

       --drop-old-templates
	   If a translation has an entire template that is not in the master file (and thus is probably an old template), drop that entire
	   template.
