我想01.从文件名中删除。我发现了几个与我相同的问题，但在我的 centos 7 安装中没有答案对我有用。

/^\d\d. /g

这是我想出的正则表达式，当我在这里测试它时它匹配

http://regexr.com/

但我完全不知道如何用 sed 来实现它，或者用 rename 来查找。真是让我大吃一惊...

答案1

和zsh：

autoload zmv # best in ~/.zshrc
zmv -n '<->. (*)' '$1'

高兴的时候就删掉-n。

<x-y>x匹配和之间的十进制数y。<->是任意数字。

答案2

仅sed和 的解决方案sh：

for FILE in *.mp3
do mv "$FILE" "$(echo $FILE | sed -r 's/^[[:digit:]]{2}\. //g')"
done

答案3

要删除文件名中的前四个字符：

for fpath in path/to/songs/*.mp3; do
  fname="${fpath##*/}"
  newname="${fname:4}"
  echo mv "${fpath}" "${fpath%/*}"/"$newname"
done

echo一旦您确定它正在做正确的事情，请将其删除。
