Bash进度条

Question

我正在使用以下脚本浏览whois中的大型域名列表并找到注册商(对于服务器/ DNS迁移非常有用),并且工作正常.

但是,为了方便起见,我想将进度条纳入其中.这是我的脚本,如果可以改进,请告诉我:

#!/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."

我先试过这个:http://moblog.bradleyit.com/2010/02/simple-bash-progress-bar-function.html

然后这个,但没有运气.

您认为在该脚本中实现进度条的最简单方法是什么？

这是一个你可能喜欢的花哨的进度条...

看起来像这样:

Answer 2

你可以使用pv另一种方式.

 for ... # outer loop
 do
   ...
   echo -n X
 done | pv -s $(wc -l 'your_file_list') - >/dev/null 

所以你用echo X来说当另一部分工作完成并且这是由pv计算的,它知道整个工作规模是由-s选项决定的.

我建议你使用 Xdialog、Kdialog 或 zenity 以及它的进度选项。
