command

问题 I'm trying to create a batch file that performs different 'choice' command based on the version of Windows being executed on. The choice command's syntax is different between Windows 7 and Windows XP. Choice command returns a 1 for Y and 2 for N. The following command returns the correct error level: Windows 7: choice /t 5 /d Y /m "Do you want to automatically shutdown the computer afterwards " echo %errorlevel% if '%errorlevel%'=='1' set Shutdown=T if '%errorlevel%'=='2' set Shutdown=F

问题 I'm writing a PHP script that downloads a series of generated files (using wget ) into a directory, and then zips then up, using the zip command. The downloads work perfectly, and the zipping mostly works. I run the command: zip -r /var/www/oraviewer/rgn_download/download/fcst_20100318_0319.zip /var/www/oraviewer/rgn_download/download/fcst_20100318_0319 which yields a zip file with all the downloaded files, but it contains the full /var/www/oraviewer/rgn_download/download/ directories, before

问题 What is the difference between git clone and git checkout ? 回答1: The man page for checkout: http://git-scm.com/docs/git-checkout The man page for clone: http://git-scm.com/docs/git-clone To sum it up, clone is for fetching repositories you don't have, checkout is for switching between branches in a repository you already have. Note: for those who have a SVN/CVS background and new to Git, the equivalent of git clone in SVN/CVS is checkout . The same wording of different terms is often

问题 Note: My question has nothing to do with Command schedule in Laravel which schedule not work. But in my question the scheduling works, but it cannot call the artisan command. I use laravel scheduling artisan command. I run the command directly from the console like this sudo -u www-data /var/www/market/artisan command:printer-serving 281H28 .

Specifically, I'd be most interested in knowing the lexical/practical difference between alias this=that and export that=this I have both forms ... all over the place - and would prefer to stop arbitrarily choosing one, over the

问题 I was wondering if there is a way to get Bazel to list, output, display, etc., all of the commands that can be executed from a command line that are run during a build after a clean. I do not care if the output is to the screen, in a file, etc. I will massage it into a usable form if necessary.

The command would have to

问题 is there a way to call a program from python without waiting for it to return? i created a script which copies a program to a directory and runs that program. but when i call the program from python, the python script does not exit until the program i launched exits. i have tried os.system and Popen. is there another way to do this?

问题 My current project is leveraging Spring, and our architect has decided to let Spring manage Services, Repositories and Factory objects, but NOT domain objects. We are closely following domain driven design. The reasoning behind not using spring for domain objects is primarily that spring only allows static dependency injection. What i mean by static dependency injection is that dependencies are specified inside xml configuration and they get "frozen". I maybe wrong, but my current
