use variable to set the range of a for loop
Hi;
For sure there's an easy answer to this one that I am not finding..
I first set a variable, say
b1a:] max=5
then I want to use max to set the range for a for loop like so (it should run for i in 1:5)
b1a:] for i in {1..$max}; do echo $i; done
{1..5}
I would like the output to match this:
b1a:] for i in {1..5}; do echo $i; done
1
2
3
4
5
Any ideas?
Thanks!

done
Instead of printing 1 to 24 nos, it gives o/p as: 1..24
Please help me
Thanks in advance. (2 Replies)
