Simple xargs replacement for Windows Shell

xargs builds the command from the standard input - however, it is not available for Windows command shell... therefore I 've decided to build one and it turns out a Batch script is enough...

Source: https://github.com/DoctorLai/BatchUtils/blob/master/xargs.cmd

@echo off
:: example:   git branch | grep -v "develop" | xargs git branch -D
:: example    xargs -a input.txt echo
:: https://helloacm.com/simple-xargs-batch-implementation-for-windows/
setlocal enabledelayedexpansion

set args=
set file='more'

:: read from file
if "%1" == "-a" (
    if "%2" == "" (
        echo Correct Usage: %0 -a Input.txt command
        goto end
    )
    set file=%2
    shift
    shift
    goto start
)

:: read from stdin
set args=%1
shift

:start
    if [%1] == [] goto start1
    set args=%args% %1
    shift
    goto start

:start1
    for /F "tokens=*" %%a in (!file!) do (
        %args% %%a
    )

:end

Delegate to @justyy

@justyy runs a automatic delegation service for nearly a year now. Delegate to @justyy for at least 5 SP and start receiving daily payout as interests (from 8% to 10% APR). Also, as a supporter, the delegators will start to receive complimentary/curation upvotes (as a thank you) per day from e.g @justyy and a few other curation trails. For more information, read this. The voting weight algorithm is open source.

• Delegate to @justyy - at least 5 SP to join (automatically)
• Undelegate to @justyy (Quit) - SP returned by steem blockchain in 5 days
• View Current Delegators/Supporters

Please note that the SP you enter is the final amount to delegate. For example, if you already delegate 10 SP and you want to delegate another 5 SP, you will need to enter 15 SP (instead of 5 SP) in the delegation form.
