击进度条 [英] Bash progress bar

问题描述

我用下面的脚本要经过的whois域的大名单，并找到登记处（用于服务器/ DNS迁移很有用），它工作正常。

I'm using the following script to go through a large list of domains in whois and find the registrar (useful for server/DNS migrations) and it works fine.

不过，我想结合一个进度条到它只是为了方便起见。这里是我的剧本，如果它可以提高让我知道：

However I am wanting to incorporate a progress bar into it just for the sake of convenience. Here's my script, if it can be improved let me know:

#!/bin/bash
for f in `cat /var/www/vhosts/domainlist`
 do
   if
   domain=$f
   [ "$domain" ] ;
   then
    whois $f | grep -i domainregistrar > /dev/null
     if
     [ $? -le 0 ] ;
     then
      echo $f >> our_registrar
     else
      echo $f >> external_registrar
     fi
   fi
 done
echo "Done, check our_registrar file."

我已经试过这首：<一href=\"http://moblog.bradleyit.com/2010/02/simple-bash-progress-bar-function.html\">http://moblog.bradleyit.com/2010/02/simple-bash-progress-bar-function.html

然后这但没有运气。

你有什么估计是让落实到该脚本的进度条最简单的方法？

What do you reckon is the easiest way to get a progress bar implemented into that script?
