Bourne Shell For i in (seq)

Question

I want to write a loop in Bourne shell which iterates a specific set of numbers. Normally I would use seq:

for i in `seq 1 10 15 20`
   #do stuf         


        

Answer 1

Another variation using bc:

for i in $(echo "for (i=0;i<=3;i++) i"|bc); do echo "$i"; done

For the Bourne shell, you'll probably have to use backticks, but avoid them if you can:

for i in `echo "for (i=0;i<=3;i++) i"|bc`; do echo "$i"; done
