Shell error: Value too great for base (error token is "168a")-CodePudding

I get this error message for my shell script below:

./my_script.sh line 17: f1bfab2e-168a: value too great for base (error token is "168a")

data=($( jq -r '.data' data.json  | tr -d '[]," ' ))

for i in "${data[@]}"; do
  echo "${data[i]}"
done

(data is made up of array elements that are a series of letters and numbers such as f1bfab2e-168a-4da7-9677-5018e5f97g0f )

I've referenced other Stack Overflow posts that provide solutions such as variable indirection or characters getting interpreted as octal numbers but I have been unable to resolve this error.

When using variable indirection such as

data=($( jq -r '.data' data.json  | tr -d '[]," ' ))

for i in "${data[@]}"; do
  echo "${data[${!i}]}"
done

"${data[${!i}]}" ends up only referencing the first array element for some reason. So if my array has two elements abc123 and bcd234, then what gets printed is just abc123 abc123 instead of abc123 bcd234. I don't exactly understand why and what's going on there.

Additionally, I don't think that bash is interpreting any of my characters as octal numbers here so a solution for that situation does not apply to my case.

What significance does 168a have to bash?

CodePudding user response：

The i is already the item of the array, not the index, as you seem to believe. This should work:

for i in "${data[@]}"; do
  echo "$i"
done
