How to get a command to run through each line of text
Hi, just wondering can anyone tell me what is the appropriate way to get a line of code to run through each line, I know you have to pipe the file with the code but am having trouble with it. Here is a sample from the text (it has alot of lines!) I want to convert and the code to do it (would take ages to do line by line)
xargs is a command that's been a bit of a nemesis for a while now, finally forcing myself to try to understand and use it instead of a million for loops.

If "xargs" can do the job, then one loop can also, and the resulting script can be repurposed. Any time more than one loop is needed, then "xargs" is not just bad judgment but out of the question.
Bash programming doesn't have to look like crap -- that's optional and at the discretion of the programmer:
Code:
for ((y = 1;y <= 12;y++))
do
for ((x = 1;x <= 12;x++))
do
printf "%4d" $((x*y))
done
echo
done
