scripting

问题 So I wrote this short script (correct word?) to download the comic images from explosm.net comics because I somewhat-recently found out about it and I want to...put it on my iPhone...3G. It works fine and all. urllib2 for getting webpage html and urllib for image.retrieve() Why I posted this on SO: how do I optimize this code? Would REGEX (regular expressions) make it faster? Is it an internet limitation? Poor algorithm...? Any improvements in speed or general code aesthetics would be greatly

问题 I am writing multi-threaded solution that will be used for transferring data from different sources to a central database. Solution, in general, has two parts: Single-threaded Import engine Multi-threaded client that invokes Import engine in threads. In order to minimize custom development I am using Roslyn scripting. This feature is enabled with Nuget Package manager in Import engine project. Every import is defined as transformation of input table – that has collection of input fields – to

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 4 years ago . I'm looking for a .NET library that does a specific task. Say my app has been sent a program (in some script language) and I want my app to run that script. That script could come from an openly hostile individual, but I want to run it anyway. (Like JavaScript in a browser.) var sc = new SecureScript(

问题 I'm attempting to use C# as a scripting language using CSharpCodeProvider (using VS2010 and .NET 4.0). I want the scripts to be run in a restricted AppDomain with minimal permissions. Currently, I'm getting an exception while trying to instantiate a class in the AppDomain (The call to CreateInstanceAndUnwrap() ). Here is some simplified code that reproduces the exception: using System; using System.Collections.Generic; using Microsoft.CSharp; using System.CodeDom; using System.CodeDom

问题 I want to run a command inside my bash script with or without a -v flag depending on if the environment variable $VERBOSE is defined. Something like this: #!/bin/bash /usr/local/bin/mongo-connector \ -m $MONGO_HOST \ -t $NEO_URI \ [if $VERBOSE then -v ] \ -stdout 回答1: #!/bin/bash /usr/local/bin/mongo-connector \ -m $MONGO_HOST \ -t $NEO_URI \ ${VERBOSE:+-v} \ -stdout If VERBOSE is set and non-empty, then ${VERBOSE:+-v} evaluates to -v . If VERBOSE is unset or empty, it evaluates to the empty

问题 I would to take in some login information for a script have written in to be used by many users. In python I set the input_raw to read from dev/tty but it fails horribly when i am connecting to the script being run on a server through ssh. Thoughts? Workarounds? I would prefer to avoid hard coding usernames into the script. Please and thank you. 回答1: Try using the -t option to ssh: -t Force pseudo-tty allocation. This can be used to execute arbi- trary screen-based programs on a remote

问题 I have to write a bash script that makes lot of things. I'd like to print messages as nice as init scripts do. For example: Doing A... [OK] Doing B... [ERROR] .... Do you know any way to make this? Thanks in advance 回答1: On all my Linux boxes, the code to do that is in the file: /etc/init.d/functions If you include that file ( . /etc/init.d/functions ) and then run your code doing this: action /path/to/prog args you will get the functionality you want. 回答2: The /etc/init.d/* scripts follow a

问题 Using zsh, I'm trying to put a step in my ~/.zprofile where I interactively ask a yes/no style question. At first I tried this bash-style approach, but I saw errors of this form: read: -p: no coprocess (I'm aware that typically the zsh syntax is different from bash's - I tried preceding it with a sh emulation command - emulate -LR sh - but it made no difference). This page implied the syntax might be different, so guided by this page and the zsh man page, I tried this instead: read -q REPLY?

问题 I need to create a script, which concatenates multiple text files into one. I know its simple to use type *.txt > merged.txt But the requirement is "concatenate files from same day into file day_YYYY-DD-MM.txt" I am linux user and windows batch is hell for me. EDIT: Its Windows XP 回答1: Windows type command works similarly to UNIX cat . Example 1: Merge with file names (This will merge file1.csv & file2.csv to create concat.csv) type file1.csv file2.csv > concat.csv Example 2: Merge files with

问题 I've two VB Scripts. Say First.vbs and Second.vbs . Frist.vbs calls Second.vbs each time some action/event happens. I am trying to send two parameters from Frist.vbs to Second.vbs using the following code: Contents of First.vbs : Set objShell = Wscript.CreateObject("WScript.Shell") param1 = "Welcome" param2 = "Gokul Nath" objShell.Run "Second.vbs" & " " & param1 & " " & param2 Set objShell = Nothing Contents of Second.vbs : param1= Wscript.Arguments.Item(0) param2 = Wscript.Arguments.Item(1)
