发帖数: 15 | 1 In this script:
for i in 1 2 3 4; do echo $i; done
It will print 1 2 3 4. But if I want to loop from 1 to N which is very large,
e.g, 100000, how to do that in bash or ksh using "for" loop? Is there anything
like "for i in 1:10000"? This one does not work.

if there is a short cut other than this way.
Thanks any way.
large,
anything
