hi im new to this shell scripting. I was assigned to develop some code that increased from 0 to 9 in sort of a pyramid. This is what the output should look like.
0
01
012
0123
01234
012345
0123456
01234567
012345678
0123456789
here is my code please help because im confused. some advice would be really appreciated. thanks
#!/bin/bash
cnt=0
while [ $cnt -le 9 ]
do
echo $cnt
while [ $cnt -le 9 ]
do
cnt=$((cnt+1))
echo $cnt
done
done
echo
exit
Let's work with what you have.
counter initialized to zero
while counter less or equal to nine; do
row initialized to zero
while row is less or equal to counter; do
echo -n row #-n suppress echo from adding a newline
increment row by one
done
echo
increment counter by one
done
finishedthank you so much. now i understand what i was missing. :)
Good deal - I was thinking you could recreate that pyramid doing a little less work, if you have "seq" to work with:
#!/bin/bash
cnt=0
while [ $cnt -le 9 ]
do
echo `seq 0 $cnt`
cnt=$((cnt+1))
done
echo
exithost # ./program
0
0 1
0 1 2
0 1 2 3
0 1 2 3 4
0 1 2 3 4 5
0 1 2 3 4 5 6
0 1 2 3 4 5 6 7
0 1 2 3 4 5 6 7 8
0 1 2 3 4 5 6 7 8 9
Of course, whatever works best for you is what you should go with :)
Best wishes,
Mike
