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:

Postscript:

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