我有这个数据列表，我按摩了这个。有些数字丢失了 - 正如第7行以CPB开头所见

我在这个黑客脚本中添加了一个前缀。数字是多少并不重要 - 我在其余部分之后 - 不完全是唯一标识符。他们是一个更优雅的方式 - 没有回应$ line替换为sed。

while read line ; do 
 if  [[ $line =~ ^[0-9] ]] ; then 
   echo $line ; 
 else 
   echo $line | sed -e 's/^/0000000000 /';
fi ; 
done < /tmp/comeandplaywithus > /tmp/danny

Answer 2

Sed本身就完全做到了

sed '/^[0-9]\{9\}/! s/^/000000000/' YourFile

从9位（!）开始选择不是（/^[0-9]\{9\}/）的行，并在这种情况下添加9（仅限）

bash脚本为行添加前缀。
