scripting

问题 I'm building a javascript application using object oriented techniques and I'm running into a problem that I hope someone here can help me resolve. The following method is designed to return an array populated with rows of data from a web SQL database: retrieveAllStoreSearches : function(){ this.db.transaction( function(transaction){ transaction.executeSql( "SELECT name,store,address FROM searchResults ORDER BY name ASC", [], function(transaction, results){ var returnArr = []; for(var i = 0;

问题 I need a script in any language to capitalize the first letter of every word in a file. Thanks for all the answers. Stackoverflow rocks! 回答1: In Python, open('file.txt').read().title() should suffice. 回答2: Using the non-standard (Gnu extension) sed utility from the command line: sed -i '' -r 's/\b(.)/\U\1/g' file.txt Get rid of the " -i " if you don't want it to modify the file in-place. note that you should not use this in portable scripts 回答3: C#: string foo = "bar baz"; foo = System

问题 Running Fedora 9/10, Apache 2, PHP 5... Can I run a shell script as root, from a PHP script using exec()? Do I just give Apache root priveleges, and then add "sudo" in front of them command?

Currently I have a shell script that just runs the app, start.sh: #!/bin/bash /path/to/my/app/appname And a script that kills the app, stop.sh: #!/bin/bash killall appname Would I just do: <?php exec("sudo start.sh"); ?> Thanks in advance.

问题 I am wondering is there a way to refresh the HKLM registry key HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer - without restarting the shell. I would like to be able to do this without restarting explorer. Is there any known way to do that ? So far, I found only this thing: RUNDLL32.EXE USER32.DLL,UpdatePerUserSystemParameters ,1 ,True which doesn't work for my case. It looks insane to me that MS made Explorer so it can't re-read its configuration while running) but you

问题 I have created a database model in Visio Professional (2003). I know that the Enterprise version has the ability to create a DB in SQL Server based on the data in Visio. I do not have the option to install Enterprise. Aside from going through the entire thing one table and relationship at a time and creating the whole database from scratch, by hand, can anyone recommend any tool/utility/method for converting the visio database model into a SQL Script that can be used to create a new DB in SQL

问题 I've searched high and low, but all the suggestions and tips I've found do not work for some reason. I have a batch file that is being invoked as such: cmd /C "automateMyProgram.bat >> automation.log 2>>&1" That works great: automation.log gets loaded with all the stdout and stderr for that particular batch file. However, within that batch script I have the following command: start php updateDB.php param1 param2 ^> updateDB.log The php script does get executed just fine and reads in the

问题 This is what I have been trying and it is unsuccessful. If I wanted to check if a file exists in the ~/.example directory FILE=$1 if [ -e $FILE ~/.example ]; then echo "File exists" else echo "File does not exist" fi 回答1: You can use $FILE to concatenate with the directory to make the full path as below. FILE="$1" if [ -e ~/.myexample/"$FILE" ]; then echo "File exists" else echo "File does not exist" fi 回答2: This should do: FILE=$1 if [[ -e ~/.example/$FILE && ! -L ~/example/$FILE ]]; then

问题 If you have a hash (or reference to a hash) in perl with many dimensions and you want to iterate across all values, what's the best way to do it. In other words, if we have $f->{$x}{$y}, I want something like foreach ($x, $y) (deep_keys %{$f}) { } instead of foreach $x (keys %f) { foreach $y (keys %{$f->{$x}) { } } 回答1: Here's an option. This works for arbitrarily deep hashes: sub deep_keys_foreach { my ($hashref, $code, $args) = @_; while (my ($k, $v) = each(%$hashref)) { my @newargs =
