command

问题 I'm a beginner at this so just mind me if I ask anything obvious. I'm trying to install an apk to my device using adb install apk.apk however, the apk is around a few hundred MB big and it takes some time. Is there some sort of progress bar that I could implement in the command window to show the progress? I've seen stuff for adb push/pull . I'm not sure if it's the same. I'm running this in Windows 8.1 . I also have an adb environment variable set up. Thanks so much. 回答1: Well, adb install

问题 How can I define an emacs command X that does something and then calls another emacs command Y and also copying the interactive interface of the command Y too? I want to define an altenative version of query-replace with temporarilly toggled value of case-fold-search: (defun alt-query-replace (a b c d e) (interactive) (let ((case-fold-search (not case-fold-search)) (query-replace a b c d e))) This doesn't work.

问题 I want to call SVN commands (update , commit) from a java program. any help ? SVN : Tortoise SVN Environment : java program will be running inside a jBoss server. 回答1: It's a really, really bad idea to use a GUI SVN client from within an app server.

It,s much, much better ot use a Java implementation of SVN, such

问题 It seems that xargs doesn't pass all the arguments at once, in says in the manual that xargs executes the command (default is /bin/echo) one or more times , I heard that the reason for this is that xargs chops the passed in arguments into groups and pass them to the command group by group. If this is correct, anyone knows how this group size is determined? Thanks 回答1: Use the --show-limits argument. It will list the existing limits on your system. $ xargs --show-limits Your environment

问题 I need to rename a directory in hdfs. What is the command for that ? hadoop fs -mv <src> <dest> The above command moves the src folder into dest folder. Instead of, I want the src folder to be renamed as dest . 回答1: Rename is not in hadoop, but you can move, hadoop fs -mv oldname newname 回答2: I think you are missing the point about mv command(linux/hdfs). When the destination already exists, if it's a file, an error message mv: 'dest': File exists . In case of directory, the source will go

问题 I was wondering how a window opened through ShowDialog is treated in the Visual Tree. For example, Window A opens Window B through a ShowDialog. When firing a routed command on Window B, Window A does not receieve the command (even though it is listening for it). Is there any way to make this work? Thanks! Jon 回答1: We run into this situation all the time in our application. We use the Window.Owner property and ICommandSource.CommandTarget property for this. For example, in Window A:
