I have separated some tracks from mp3 mixes using mp3splt.

BASH: (mp3splt -c('**!!***use .cue file***!!**') [cuefile.cue] [nonstopmix.mp3] ~for anyone interested, is in the Ubu repos~)

And I ended up with these filenames: "Antares" - 01 - "Xibalba".mp3 which is not a format I prefer, now I've made it a little project to change them with a shell script but its more difficult than I anticipated.

I want to change the filename from:

"Antares" - 01 - "Xibalba".mp

to:

01-Antares_-_Xibalba.mp3

so far I've used :

for var in *.mp3; do mv $var {var/"/}; done

and I could repeat that until I'm through, delete the 0x number and add one but I'd like to do it more efficient.

Could anyone give me a pointer (!not a script!) ? I'd still like to write it myself but there's so much options that I'm a bit lost.

so far I thought to use this program flow:

  1. read all the filenames containing .mp3 and declare as variable $var

  2. strip $var from quotes

  3. select 0x number, append delimiter _ (0x_)

  4. move 0x_ to the beginning of the string

  5. select remaining ' - - ' and change to '-'

done

which bash programs to use? especially changing the 0x puzzles me cuz I need a loop which increments this number and test if it is present in the filename variable and then it has to be changed.

在 python 2.x 中很容易做到。您可以在任何您想要的语言中使用此逻辑。

import string
a=raw_input('Enter the name of song')
a=a.replace('"', "")
a=a.replace('.mp', ' .mp3')
words = a.split()
print words[2]+'-'+words[0]+'_-_'+words[4]+words[5]

逻辑：

我删除了“，然后将 .mp 转换为 .mp3，然后拆分字符串，创建一个列表（数组），然后根据需要打印元素。

尝试这样做：

rename -n 's/"(\w+)"\s+-\s*(\d+)\s*-\s*"(\w+)"\.mp/$2-$1_-_$3.mp3/' *mp

从shell提示。它非常有用，您可以像我一样将一些技巧放在替换中。

当您的测试有效时，您可以移除-n（试运行模式开关）。

警告 还有其他同名的工具可能会也可能不会这样做，所以要小心。

如果您运行以下命令 ( linux)

$ file $(readlink -f $(type -p rename))

你有一个像

.../rename: Perl script, ASCII text executable

那么这似乎是正确的工具=）

如果不是，则使其成为默认值（通常已经如此）Debian和衍生，例如Ubuntu：

$ sudo update-alternatives --set rename /path/to/rename

最后但同样重要的是，这个工具最初是由 Perl 的父亲 Larry Wall 编写的。
