Jeff wrote at errors in parameter expansion on filenames named after negative numbers
My best direction at this point is to do something like
[[ $b =~ ^-0+([0-9]+)$ ]] && b=-$BASH_REMATCH[1]to strip leading zeroes from possibly-negative numbers
I was wondering if the starting digit 0 in the pattern is necessary.
In other words, is pattern ^-0+([0-9]+) the same as ^-0+([1-9]+)? Thanks.
