Use Python to traverse (Linux) subdirectories and find out the specified string with (extension) black-and-white list feature

One of the notes of software & Web Architects _ complements the imperfect second of Linux commands with a Python script:

Traverse (Linux) subdirectories (or folders) with a Python script and find the specified string, and display:

1, directory location;

2, (string) where the file name;

3. The line number where the string is located (in the file);

4. And display the bank's information, showing the 256 characters of the bank (starting from the bank).

#并且支持把扩展名放进脚本中 the list of black and white (extensions) that are stored in an array:

Both in the "white extension" type of file: Search, such as *.txt, *.log, *.cnf, *.conf, *.php and other (type) files contained, find out ...

Then look again at the "black extensions" that are not included, either: not including *.myd, *.jpg, *.bmp, *. RAR, *.class, etc. file, traverse find again ...

The script (code) is as follows:

#!/use/bin/env python

Python (written) script is really concise!

But put the csdn to Python's "indentation" all messed up ... So I think this is Python's only "nasty" place ...

In the Learning solution ...!!

In order to display indentation, a portion of the code is displayed on the screen ...

The code in the article is complete, but the "indentation" in Python code is "eaten" by Csdn's article publishing system!?
