Bash scripting silly question


hello.. I've found a way to increase lets say a counter... but I think my way is stupid, there must be better solution...

Code:
hey=1
hey=`echo $hey+1 | bc`
I think the best way is something like hey={$$hey}+1
but I'm not familiar with the right syntax.


Thanks.

If it is a loop counter, you can use this form of the "for" command:

for (( index=100; index<200; index++ )); do

The old (and more portable) way :
Code:
hey=`expr $hey + 1`
