scripting

问题 I'm writing a deployment script and have run in to a strange problem... ian@baster:~$ sudo echo "Build: "$REVISION" - Deployed: "$(date +%Y-%m-%d) > /home/www/prod/www/revision.html -bash: /home/www/prod/www/revision.html: Permission denied but... root@baster:~# echo "Build: "$REVISION" - Deployed: "$(date +%Y-%m-%d) > /home/www/prod/www/revision.html root@baster:~# more /home/www/prod/www/revision.html Build: - Deployed: 2011-01-28 then... ian@baster:~$ sudo ls -l /home/www/prod/www total 28

问题 I am looking as the title says to kill a process (for example name.exe) on multiple remote machines. I can do it individually using pskill or taskkill using (for example): pskill -t \ -u -p name.exe but this becomes impractical with 50+ machines. Is there a way to make it read a text file of IP Addresses like psexec does using the @C:\name.txt or in powershell or something similar? All devices are on the same domain. Thank you in advance for your help. 回答1: If you have a text file with a list

问题 I am working on this complicated (for me...) automation and one part is a batch script Started (not Called) from another one. Now, it's all work-in-progress and I'd like to be able to replace the Started batch script with a simple instruction that would do such that the Start-ing script, after having started the child script, has: %ERRORLEVEL% EQU 1 (And then I could work on the error-handling aspects and test stuff) But also something nice that doesn't put the system in an unnatural state

问题 This seems like it should be easy. I've never used JScript before and I'm looking at the JScript api provided by microsoft but no luck. Here's what I have: var fso, tf; fso = new ActiveXObject("Scripting.FileSystemObject"); tf = fso.CreateTextFile("New Tracks.txt", true); var objShell = new ActiveXObject("Shell.Application"); var lib; lib = objShell.BrowseForFolder(0,"Select Library Folder",0); items = lib.Items() for (i=0;i<items.Count;i++) { fitem = items[i]; tf.WriteLine(fitem.Name); }

问题 I have two variables: X and Y. The value of X will be a date given in the format mmddyy and I want to calculate the date preceding that date and have it be returned in in the format yyyymmdd . Let me give you an example. When X="091509" ( mmddyy format) Y should be "20090914" ( yyyymmdd format) 回答1: ~$ date -d "20090101 -1 day" Wed Dec 31 00:00:00 CET 2008 And if you want to retrieve the date in a custom format you just throw in some format strings. ~$ date -d "2009-09-15 -1 day" +%Y%m%d

问题 Say you were mainly a C-syntax like programmer and Linux systems administrator, and you were tasked with creating some simple automation tasks on Windows (monitoring of back-up files, process monitoring, ...). Which language would you prefer to write your scripts in? There's a large collection of VBS-scripts out there (using VB syntax), but I'd prefer anything more C-related. What are your best experiences in using scripts for Windows? Any obvious down- or upside to a certain language? 回答1: I

问题 I'm trying to set a variable based on a bunch of input conditions. Here's a small sample of the code: #!/bin/bash INSTANCE_SIZE="" case "$1" in "micro") $INSTANCE_SIZE="t1.micro" ;; "small") $INSTANCE_SIZE="m1.small" ;; esac echo $INSTANCE_SIZE When I run the script with the -ex switch and specify the proper argument: + case "$1" in + =m1.small ./provision: line 19: =m1.small: command not found 回答1: You need to remove the $ sign in the assignments - INSTANCE_SIZE="m1.small" . With the dollar

问题 I would like to telnet into my router, and I want to automate it so I do not have to login all the time, as I do it several times a day. Is there another method apart from sendkeys in VBS? This is because that physically types, so the telnet window needs to be active, with is rather annoying. I tried a batch file, but I am getting really strange results. Here it is: telnet 192.168.1.254 REM This is the router IP ping 255.255.255.255 -n 1 -w 1000 > nul REM This is to wait for the router if its

问题 Does anybody know if there is any tool for packing a Python project that uses several files and modules into a single script? 回答1: Save this as python_header.py : #!/bin/env/python # -*- coding: ascii -*- import os import sys import imp import tarfile import tempfile RUN_MODULE = "__run__" SENTINEL = 'RzlBTXhya3ljIzl6PFFkQiRKLntEdHF+c2hvWid0IX5NVlxWd' \ 'FxcJ0NWQ2xKVUI0TVEuNl0rWUtnKiRr'.decode('base64') class FileOffset(object): def __init__(self, fileobj, offset=0): self._fileobj = fileobj

问题 This Lua code, creates a table and dynamically adds a new member. Running this I can get "hello" on the screen as expected: foo = {} foo.x = "hello" print(foo.x) But now I'm using SWIG to bind some C++ classes to Lua. For that purpose, in a test.i (SWIG module file) I created a simple class like this: %module test %inline %{ class Foo { public: Foo() { X = 0; } void SetX(int x) { X = x; } int GetX() { return X; } private: int X; }; %} Then I wrote a test Lua code like that: obj = test.Foo()
