问题 I am having trouble with variable text encoding when opening text files to find a match in the files' contents. I am writing a script to scan the file system for log files with specific contents in order to copy them to an archive. The names are often changed, so the contents are the only way to identify them. I need to identify *.txt files and find within their contents a string that is unique to these particular log files. I have the code below that mostly works. The problem is the logs may

问题 In a C# program I am importing a large text file (300mb) into a MySQL database via the MySqlBulkLoader function of the MySql .Net Connector. The import takes quite a long time and results in almost 100% disk usage on the Windows 2003 Server it is running on. In an attempt to speed up the import the program nows splits the big file into smaller chunks. Would it be possible to read the small file chunk (8mb) into memory (ie array) and then pass it to the MySQLBulkLoader as a file? The bulk

Now, the question is: how to explode this file into an array, so I can search for a specific name and display that block´s contents? I´ve tried to explode like this: header("Content-type:text/plain"); $file = fopen("cc/cc.txt", "r"); while (!feof(

问题 Suppose I have a 400K text file which I want to read from a javascript. The problem is, my target audience have a slow connection, so 400k might take too long to load. I suppose I need to compress the file, but well, how can I decompress it via javascript on the client side? Is it worth it, or will the time needed for decompression negate the time saved in downloading? UPDATE Just to be clear, the file is text (data) not code. 回答1: You can GZip the text file, and sent it to the browser. That

问题 I have a program that outputs many calculations and results to the console through the print statement. I want to write some code to export (or save) all the contents of the console to a simple text file. I searched StackOverflow and other sites but I found some methods to redirect the print statement to print to a file directly, but I want the program to work normally, to display outputs to the console, then to save its contents AFTER all operations of the program done. I am using PyCharm
