问题 Assuming you can get a dynamic interpreter; can statically compiled languages replace scripting language? I never quite understood why anyone would use a scripting language? I am talking about on PC, not a limited system which needs a simplistic interpreter. I seen some python install scripts and seen similar python and C# solutions to a problem. So why use a scripting language? NOTE: There are things that bother me about C#, i am not asking why not use C# instead. I am asking why use a

问题 What is the difference between the two below: find . -type f -name \*.bmp find . -type f -name *.bmp I have tested,they both return the same result,so is there anything different _deep inside_ ? Added from the removed answer: So it is to avoid the shell expansion for the special ***** character,solely pass * as a argument to the find command and let it process it. But on my machine,they are all good, both return the bmp files in and below the current directory,to name a few,the result is like

问题 I wrote this script but it's not working properly.Anyone can help? It's supposed to check download limit and download used by a user and then do some action i.e to remove the user from active ppp list but it has some flaws which is that I can't get the actual-profile value in a variable so instead I save the Profile name in Comment with the user manager user account so then I can get the profile name in the variable but that's not how I want it to be..So that's why how to get the actual

问题 When I write a simple script and pass it to runhaskell, it works fine, but not when I add a shebang and try executing it directly.
