Network removing leading zero
Hi,

I do have a code as follows:

function deHex {
if [[ ${1:0:1}=0 ]]; then
deHexDate=${1:1:$2}
fi
}

The description given for the above code is as follows:
# description: removes leading zero so value will not be recognized as hex
# usage: deHex <value_parameter> <value_input_length>


But I am not that much comfortable with the code. So can anyone explain the above code..
