问题 I am trying to run the command "sudo service awslogs start" from a python script. I cannot use 'sudo' so I change the command to "su -c 'service awslogs start'" but that does not seem to work either. I still get the error su: user if=/dev/null does not exist or standard in must be a tty Any ideas as to how to fix this? 回答1: sudo -S reads from stdin, see man sudo : -S, --stdin Write the prompt to the standard error and read the password from the standard input instead of using the terminal

问题 Just discovered MacRuby this afternoon; man is that ever COOL! However, I've run into some difficulties while attempting to extend an old project with some MacRuby-fu. Here's the deal: So I have a superclass in Objective-C that looks like this: @implementation Foo - (id) init { if (self = [super init]) { //Do nothing, don't have enough data... } return self; } - (id) initWithName:(NSString*)n andLocation:(NSString*)loc andSomethingElse:(Bar*)b { if (self = [super init]) { //Set a LOT of

问题 I've asked a question similar and can be found here: Python Login Script; Usernames and Passwords in a separate file However, I'm now looking to extend the script so that it can look at multiple passwords per user account in the text file and know that the first password is the legitimate password while any other specified password linked to that account will throw up an error message. So right now the external username file is set up so that its: Admin:AdminPW Now I'm looking to extend it to

问题 When I run a SAP script in VBA (excel) over a long period of time, the SAP session starts to slow down. If I interrupt the code and start it again, the SAP session still runs at the slow speed it was at. If I close excel and run the code again, the SAP session still runs at the slow speed. However, if I close the SAP session and reopen it and then run the code (not closing excel), the speed goes back to optimal speed again. I ran the below code (as a test) to see the speed decrease. When the

问题 I have a Swift script I'm writing to calculate the file size of an iOS framework. However, I have weird results. In one framework I have this file structure as shown in the Finder: /{FrameworkName}.framework/Modules/{FrameworkName}.swiftmodule/ /{FrameworkName}.framework/Modules/{FrameworkName}.swiftmodule/x86_64.swiftmodule /{FrameworkName}.framework/Modules/{FrameworkName}.swiftmodule/x86_64.swiftdoc HOWEVER!

问题 I'm using google docs, and some templates we are using were created using MS-Office. The resulting HTML is fat and ugly, and the 500KB per doc limitation on google makes some cleanup mandatory. I was able to find redundant "style" attributes and move them to some CSS class, and rename the most redundant classes names to shorter ones, which makes me save about 50% of the original size. Are you aware of some existing tools/scripts/lib which could do this painful job for me, or at least help me
