Pattern: Use of number with leading 0
Issue: -
ShellCheck found an integer literal with a leading zero, but containing the digits 8 or 9.
This is invalid, as the integer will be interpreted as an octal value (e.g. 0777 == 0x1FF == 511).
To have the value parsed in base 10, either remove the leading zeros as in the example, or specify the radix explicitly:
echo $((10#08))
Example of incorrect code:
echo $(( 16 - 08 ))Example of correct code:
echo $(( 16 - 8 ))
