将文件夹名称用作文本文件中的列

Question

懒惰的我正考虑在一些文本文件中添加一列.

文本文件位于目录中,我想将目录名添加到文本文件中.

就像文件text.txt夹中的文本文件一样the_peasant:

has a wart    
was dressed up like a witch     
has a false nose

会成为:

the_peasant has a wart    
the_peasant was dressed up like a witch    
the_peasant has a false nose

然后我在其他文件夹中有类似的文本文件,名为"the_king"等.

我认为这是find命令,bash脚本和sed的组合,但我无法看透.有任何想法吗？

之前的目录和内容：

\n\n

% find . -name \'text.txt\' -print -exec cat {} \\;       \n./the_king/text.txt\nhas a wart    \nwas dressed up like a witch     \nhas a false nose\n./the_knight/text.txt\nhas a wart    \nwas dressed up like a witch     \nhas a false nose\n./the_peasant/text.txt\nhas a wart    \nwas dressed up like a witch     \nhas a false nose\n

\n\n

代码（wart.py）：

\n\n

#!/usr/bin/env python\n\nimport os\n\ntext_file = \'text.txt\'\ncwd = os.path.curdir # \'.\'\n\n# Walk thru each directory starting at \'.\' and if the directory contains\n# \'text.txt\', print each line of the file prefixed by the name containing\n# directory.\nfor root, dirs, files in os.walk(cwd):\n    if text_file in files: # We only care IF the file is in this directory.\n        print \'Found %s!\' % root\n        filepath = os.path.join(root, text_file) # \'./the_peasant/text.txt\'\n        root_base = os.path.basename(root)       # \'./the_peasant\' => \'the_peasant\'\n        output = \'\'\n        with open(filepath, \'r\') as reader:      # Open file for read/write\n            for line in reader:                  # Iterate the lines of the file\n                new_line = "%s %s" % (root_base, line)\n                print new_line,\n                output += new_line               # Append to the output\n\n        with open(filepath, \'w\') as writer:\n            writer.write(output)                 # Write to the file\n\n        print\n

哪个输出：

\n\n

之后的目录和内容：

\n\n
