升级后重命名脚本不起作用。需要一个新的

升级后重命名脚本不起作用。需要一个新的

递归文件重命名器 - 非常有用的 python 脚本在升级 Python（Pyt2 到 Pyt3）后停止工作。有人能找到并解决问题吗？谢谢你！

例如，这些文件：

'Linux příručka českého uživatele.pdf'
'LINUXTERO příkazy které se vždy hodí.pdf'
“Práce s archívy příkazové řádka.pdf”
'Rekurzivní grep.txt'

更改这些文件：

linux_prirucka_ceskeho_uzivatele.pdf'
linuxtero_prikazy_ktere_se_vzdy_hodi.pdf
prace_s_archivy_prikazove_radka.pdf
rekurzivni_grep.txt

程序员是捷克人，所以我必须通过谷歌翻译成英语......

当我启动脚本时，按摩失败，如下所示：

linq@legion5:~/test-renamer/ask_stackexchange_folder$ vycisti.py
文件“/home/linq/bin/vycisti.py”，第 62 行
print "警告：'%s' 仍然不是有效名称" % fileName
    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ^^^^^^
语法错误：调用“打印”时缺少括号。您的意思是 print(...) 吗？

这是脚本：

#!/usr/bin/python
# -*- coding:  utf-8

'''Renames all files and directories in the current directory to
    to have some culture. It also works recursively in nested ones
     directories. The changes are as follows:
     Czech characters -> English
     cancels all dashes and spaces at the beginning of the name (damn, what kind
             the names make up would deserve a few slaps)
     special characters are replaced by '_', I take the hyphen at mercy, but not at the beginning
     the (unnecessary) '_' around the hyphen is discarded
     multiple '_'s are replaced by a single occurrence
     everything will be converted to lowercase

     The result should be a title where there are only letters, underscores,
     numbers, periods and dashes (but not at the beginning).
     It writes exactly what it does to standard output
     Usage: vycisti.py [ > logfile ]

正如评论中所说，Python2 已被弃用。还有其他工具可以解决这个问题...

使用珀尔的rename:

$ rename -u utf8 -n  '
    BEGIN{use Text::Unidecode} # 'import' needed extra module
    s/.*/unidecode($&)/e;      # decode utf8 -> ascii
    s/\s+/_/g;                 # s/[[:space:]]/_/g
    y/A-Z/a-z/                 # translate uppercase to lower
' ./**/*.*                     # ** enable recursion¹

1zsh默认情况下，bash 需要shopt -s globstar在命令之前运行。

需要sudo apt install rename libtext-unidecode-perl包（Debian*/Ubuntu/Mint...）。

当输出看起来令人满意时删除-n（又名）。dry-run

输出

rename(Linux příručka českého uživatele.pdf, linux_prirucka_ceskeho_uzivatele.pdf)
rename(LINUXTERO příkazy které se vždy hodí.pdf, linuxtero_prikazy_ktere_se_vzdy_hodi.pdf)
rename(Práce s archívy příkazové řádka.pdf, prace_s_archivy_prikazove_radka.pdf)
rename(Rekurzivní grep.txt, rekurzivni_grep.txt)

答案2

Python 2 现在是一种死亡语言（2020 年 1 月 1 日日落）

很长一段时间以来，人们编写的代码都与 python 2 和 3 兼容。所以它们很相似，但仍然存在差异。

也许最著名的是错误中提到的一个。 “print”语句现在需要括号：

打印“富”

就是现在

打印（“富”）
