It's been a while since I've done intense bash scripting and I forgot the syntax for doing multiple conditions in a for loop.
In C, I'd do:
for(var i=0,j=0; i<arrayOne.length && j<arrayTwo.length; i++,j++){
// Do stuff
}
I've been googling for a while and have only found syntax involving nested for loops, not multiple conditions to one for loop.
Sounds like you're talking about the arithmetic for loop.
for ((i = j = 0; i < ${#arrayOne[@]} && j < ${#arrayTwo[@]}; i++, j++)); do
# Do stuff
done
Which assuming i and j are either unset or zero is approximately equivalent to:
while ((i++ < ${#arrayOne[@]} && j++ < ${#arrayTwo[@]})); do ...
and slightly more portable so long as you don't care about the values of i/j after the loop.
There is not a big difference if you compare it with C
for (( c=1,d=1; c<=5 && d<=6; c++,d+=2 ))
do
echo "$c : $d"
done
x[0]="test 1"; x[1]="test 2"; for i in "${x[@]}"; do echo $i; done
for in iterates arguments. It doesn't have anything to do with "conditions" and can't do the equivalent of the c-style loop without nesting. for i in "${arrayOne[@]}" "${arrayTwo[@]}"; do would iterate the elements of each array sequentially.
