Made the code more readable, Fixed code and typo

[arafatx]

• Made the code more readable with the new syntax and fixed some variable declarations that should follow variable scope. Also removed unnecessary semicolons in code and formatting the code indention in beautiful way.

eg:

$? == 0 (BAD)
$? -eq 0 (GOOD)

$? != 0 (BAD)
$? -ne 0 (GOOD)

BAD:

function ansure_accesstoken () {
local NOW = date +%s
}

GOOD:

ansure_accesstoken () {
local now = $(date +%s)
}

BAD:

let NUMBEROFCHUNK=($FILE_SIZE/1024/1024+$CHUNK_SIZE-1)/$CHUNK_SIZE

GOOD:

((number_of_chunk = (file_size / 1024 / 1024 + CHUNK_SIZE - 1) / CHUNK_SIZE))

• Add little more test for config file before source it to prevent error

• Fixed return code when calling check_http_response function, it did not have an argument of '$?' at the end.

• Fixed typo

$? == 0 (BAD)
$? -eq 0 (GOOD)

$? != 0 (BAD)
$? -ne 0 (GOOD)

Even better if you check the command directly. Like:

command && echo "Success" || echo "Failed"

or

if command; then
  echo "Success"
else
  echo "Failed"
fi

Otherwise, the repository owner hasn't updated their code in four years, so unfortunately, I don't think there will be a merge...
