• Delete System Files containing string

  - by Fuzz Evans

  I am trying to write a batch file that will examine a given directory, read each file for a given string "Example" and then delete any files that contain the string. The files are also System Files so I don't know what the exact extension is or if that matters (maybe you can just omit a file type filter and have it read all files?). Some of the files will be locked from reading as well so it needs to handle access denial errors if that occurs, not sure how batch files handle that.

• Way to partialy match a Ruby string using Regexp

  - by Fabiano PS

  I'm working on 2 cases: assume I have those var: a = "hello" b = "hello-SP" b = "not_hello" 1 - Any partial matches I want to accept any string that has the var a inside, so b and c would match. 2 - Patterned match I want to match a string that has a inside, followed by '-', so b would match, c does not.

• String literals in python

  - by kjakeb

  Hello, Is there a way to declare a string variable in python such that everything inside of it is automatically escaped, or has its literal character value? I'm NOT asking how to escape the quotes with slashes, that's obvious. What I'm asking for is a general purpose way for making EVERYTHING in a string literal so that I don't have to manually go through and escape everything for very large strings. Anyone know of a solution? Thanks!
