scripting

问题 This question already has answers here : 'echo' without newline in a shell script (8 answers) Closed 2 years ago . Why doesn't $echo '-n' write -n on terminal although -n is written within single quotes ? 回答1: Because the quotes are processed by the shell and the echo command receives plain -n . If you want to echo -n , you can e.g. printf '%s\n' -n 回答2: you should try to use the more portable printf as far as possible. 回答3: You could try echo -e '\055n' 回答4: I found that the following just

问题 Closed. This question is off-topic. It is not currently accepting answers. Want to improve this question? Update the question so it's on-topic for Stack Overflow. Closed 3 years ago . I'm looking for a tool for automated testing. I will use scripting for testing, rather than just automating, which means that it can't just send some key-presses. It needs to examine the app's window to see if it was updated correctly. The cheaper the better, with no downside limit on cost. ;-) I need a real

问题 Inspired by "Getting the source directory of a Bash script from within", what's the Ruby way to do this? 回答1: For older versions of Ruby (< 2.0), the script being run can be found using: File.dirname(__FILE__) - relative path; or File.expand_path(File.dirname(__FILE__)) - the absolute path. For newer versions of Ruby, try: __dir__ Using __dir__ will return the script path even after a call to Dir.chdir ; whereas, using the older syntax may not return the path to the script. 回答2: Use __dir__

问题 import java.lang.management.* final String name = ManagementFactory.getRuntimeMXBean().getName(); final Integer pid = Integer.parseInt(name[0..name.indexOf("@")-1]) I tried this in my code but that gets the pid of the running program. I am running a sleeping script (all it does is sleep) called sleep.sh and i want to get the pid of that. Is there a way to do that? I have not found a very good way myself. I also used a ps | grep and i can see the process id is there a way to output it though?

问题 I have a text file with lots of links-each line has a link (i.e the separator is '\n'). i want to write a script so that each link opens in a different tab in Firefox or Internet explorer.

问题 I would like to run a shell script, from a file or from an objective-c string (within the code). I would also like the shell script's result to be stored to a variable. I would not like the shell script to be split into arguments (such as setLaunchPath when I run it). For example: running this shell script "mount_webdav idisk.mac.com/mac_username /Volumes/mac_username" instead of "/bin/mount_webdav" then the arguments. Is there anyway to do this? I am using NSTask right now, but it has caused

问题 What I currently have. Is this the best way? Have a script with lots of functions and need a way to know what OS is running before running each function. CHECK_architecture() { architecture=`uname -m` if [ "$architecture" != "x86_64" ] && [ "$architecture" != "ia64" ]; then architecture="x86" else architecture="x86_64" fi } CHECK_distro() { DISTRO=""; if [ `uname -r | egrep '(6.2-RELEASE|6.1-RELEASE|5.5-RELEASE|6.1-STABLE|5.4-RELEASE|6.0-RELEASE|5.3-RELEASE|4.10-RELEASE|4.11-RELEASE)'` ];

问题 I was just wonderin' in a .bat file, if there was a way to call an external .bat file, or even an *.exe and make it open so it 'snaps' to the top left hand corner of the screen ? Cheers 回答1: There is no direct way to position a Window from the Windows command prompt. You basically have the following options: Use a GUI automation tool, e.g. AutoHotkey which lets you script window actions. AutoHotkey e.g. offers the WinMove command: Run, calc.exe WinWait, Calculator WinMove, 0, 0 ; Move the

问题 I want to run a script when an email is received on my exchange server. I really don't have a great direction on how to implement this. I've written my script in VB and tested it on outlook. I incorrectly assumed you can run a script from a rule in Exchange like you can in Outlook. Any help would be greatly appreciated. Should I be using smtpreg.vbs or EWS or something completely different? 回答1: Exchange used to rely on event sinks for this kind of processing, but this is deprecated and not
