Shell Script
 
Hi I am new to this forum, any help would be appreciated.

I am trying to figure out how to write a script to display the numbers 1 - 9 in a row (one at a time.) Using a while loop.
For example:
1
12
123
1234
etc...

thx

Looks like an assignement ...
Who ever want to do that in the real life ?

Code:
line=
for number in 1 2 3 4 5 6 7 8 9; do
  line="${line}${number}"
  echo "$line"
done
or
Code:
line=
number=1
while [ $number -lt 10 ]; do
  line="${line}${number}"
  number=$(( $number + 1 ))
  echo "$line"
done

That one is cooler :D
Code:
echo "1
12
123
1234
12345
123456
1234567
12345678
123456789" | while read s
do
echo $s
done

That was precisely my goal in my first reply, but theYinYeti missed it.
I provided a dumb answer later just for fun, I doubt wcfour will get an A+ with it ...

Is that so? ... I was indeed surprised by the request... But then, I've done myself so strange things to achieve usefull results in shell scripting...
