问题 As you can see from the output below, I'm using the MySQL shell to change the session's wait_timeout variable to 30 seconds. It works. However, Is there anyway to set this variable from the command line? $ mysql -u root -h 127.0.0.1 -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g.

问题 I'm using argcomplete to have Tab completion in Bash. argcomplete offers global completion for bash , but doesn't for zsh . I would like to create a file ~/.zsh_completion , to contain the to be completed files. This file should generate autocompletion for those files when it's sourced from ~/.zshrc . How do I do that? 回答1: Alright there is a way to do it, but it's not the way I really wanted it to be. Anyway, here goes: Install argcomplete : $ pip install argcomplete Activate argcompolete :

问题 We're calling a PowerShell script via TeamCity. We want to pass a parameter which contains quotes, e.g.: Build step : PowerShell Script file : foo/bar/my.ps1 Script arguments : -MyParam "%system.MyParam%" Where system.MyParam is set to <xml><elem attr="value"></elem></xml> . Unfortunately, this fails with: Cannot process argument transformation on parameter MyParam . Cannot convert value " <xml><elem " to type " System.Xml.XmlDocument ". Error: "Unexpected end of file while parsing Name has

问题 I have 2 Java classes which have a symbiotic relationship. Class 1 produces some output files and Class 2 consumes the output of class 1 and validates it. Both of these classes take input from the commandline. This project is maven based. Given this symbiotic nature, I am unsure how to "connect them"? My thinking was, to write another Java class which takes in command line inputs and calls the 2 classes. However there is another uncertainty here, how could I run class 1 (in order to produce

问题 For example I am using ffplay and want to run this command -bufsize[:stream_specifier] integer (output,audio,video) At the moment I have this: subprocess.call(["ffplay", "-vn", "-nodisp","-bufsize 4096", "%s" % url]) But this says it is invalid. 回答1: As JBernardo mentioned in a comment, separate the "-bufsize 4096" argument into two, "-bufsize", "4096" . Each argument needs to be separated when subprocess.call is used with shell=False (the default). You can also specify shell=True and give

问题 I have a script that reads a configuration file that results in a set of name value pairs that I would like to pass as arguments to a function in a second PowerShell script. I do not know what parameters will be placed in this configuration file at design time, so right at the point where I need to invoke this second PowerShell script, I basically just have one variable that has the path to this second script, and a second variable that is an array of arguments to pass to the script

问题 I have to debug a program that has errors in it as part of my assignment. However, I must first pass command line arguments in order to solve this problem. I do: gdb -tui InsertionSortWithErrors which works, but after that I don't know how to pass arguments. I used gdb -help and it says something about --args which I also tried and it didn't work. I want to be able to get the debugger+the GUIand pass command line arguments. 回答1: Once gdb starts, you can run the program using "r args ". So if
