Is it possible to define n assign a value to multiple variables using a loop??
I was trying to achieve something like the following.
for (( i=0, i<=10, i++ ))
do
var_$i="value"
done
upon execution, it throws something like command not found...
thanks.
I think you would be better off with arrays. That said, you can do:
for (( i=0; i<=10; i++ ))
do
eval "var_${i}='value'"
done
echo $var_3
with array:
for i in $(seq 1 10); do
array[$i]=$(($i * $i))
done
echo ${array[7]} # -> 49
As rici notes in the comments, also consider:
declare var_$i="$value"
eval forces you to figure out how to quote value for double-expansion. Better is declare var_$i="$value" (also less subject to injection attack)
