问题 I am using bash scripting to check whether two specific directories are containing some specific number of files. lets assume 20. Is it possible to check it in a line inside a if statement? #!/bin/bash if [ [ls /path/to/dir1 | wc -l ] != 20 || [ ls /path/to/dir2 | wc -l ] != 50 ]; then echo "do this!" elif echo "do that!" fi 回答1: The syntax is incorrect: if [[ $(ls /path/to/dir1 | wc -l) != 20 || $(ls /path/to/dir2 | wc -l) != 50 ]] then echo "do this!" else echo "do that!" fi (I move the

问题 pracl is a sysinternal command that can be used to list the ACLs of a directory. I have a list of shares and I want to create a csv file such that for each ACL entry, I want the share path in one column and share permission in the next.

问题 I'm trying to call an ImageMagick command from Python 2.7 using subprocess.call. My problem is that the argument parser in subprocess puts a double quotation mark around every argument, and ImageMagick seems to have a problem with quotes around non-file arguments. What I'd like is something like this "imagemagick.exe" "im1.png" "im2.png" -alpha off ( ... ) -composite "im3.png" So far I couldn't find a way to do it with subprocess, other than manually constructing the string with ugly + " " +

问题 I guess the question in the title is clear enough.What happens when i call ApplicationCommands.Close.Execute(null,null) from my viewmodel class. I have a modeldialog which shows a usercontrol.I have a commandbinding to a button in the usercontrol which is executed in the viewmodel.I want to close the dialog after the command is executed.It can be done by using the above command to the end of the executed event.

问题 I am writing a C# winform application that starts a second process to execute shell commands like "dir" and "ping". I redirect the second process's output so my app can receive the command result. It roughly works fine. The only problem is my winform app receives the command line output as a whole instead of line by line. For example, it has to wait for the external "ping" command to finish (which takes many seconds or longer) and then receives the whole output (many lines) at once. What I
