My Command.java looks like this: public class Command { Process process; public String executeCommand(String command) { StringBuffer output = new StringBuffer(); try { process = Runtime.getRuntime().exec(command); process.waitFor(); BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream())); String line = ""; while ((line = reader.readLine())!= null) { output.append(line + "\n"); } }

问题 I have a C++ program that writes to stdout that I am trying to compile into a command line utility in XCode. I need the program compiled into a release build (which it seems, XCode calls an Archive - go figure), not run it as debug. I basically want to pipe the output of my program into a textfile like this MyProgram > TextFile.txt I can compile the program into a command line and run it like this via a Bash shell like this: Open MyProgram This spawns a new process (not what I want). However,

问题 I am writing a program in Java that needs to use terminal command to work. My function basically looks like this : public void sendLoginCommand() throws IOException { System.out.println("\n------------Sending Login Command------------\n"); String cmd="qskdjqhsdqsd"; Runtime rt = Runtime.getRuntime(); Process p=rt.exec(cmd); } public Process sendPassword(String password) throws IOException { System.out.println("\n------------Sending Password------------\n"); String cmd=password; Runtime rt =

问题 I have been trying to execute a set of commands in a powershell session through java, with no luck yet. My aim is to search a computer object in AD with the domain = "domain.com". I started with a single command. Unfortunately, the following command successfully runs in my powershell prompt: Get-ADComputer -Filter { Name -like "hostname" } –Server a.b.c.d:3268 -SearchBase 'DC=domain,DC=com' | FT DNSHostName # hostname is actual hostname provided by user and accepted in argument of Java

问题 I have this chess engine Rybka.exe, that i have to execute in java Here is an example how you run Rybka: Once you clicked on it, console opens and waits for input. So then you enter "uci" and you press enter and you wait for it to load (approx. 1 sec) and then you have to enter a few more lines as options and stuff. The problem is that I don't know how to pass those commands from java to Rybka. The fact is that those commands need to be entered one at a time, because you have to wait for some

问题 I'm running multiple commands in my Linux shell at the same time, e.g. echo "Line of text 1" && echo "Line of text 2" && complexthing | xargs printf "complexspecifier" I want to redirect all output to file1 . I know I can add >file1 after each individual command but this seems bulky. How can I do this? 回答1: exec >file1 # redirect all output to file1 echo "Line of text1" echo "Line of text2" exec > /dev/tty # direct output back to the terminal Or, if you are on a machine that doesn't have /dev

问题 I already posted similar question, but still could not get my job done, so this a a second attempt, where I would like to more clearly state my stumbling block. So basically I am in Android phone's adb shell, communicating with the GPRS modem by sending AT commands. I am able to do it by redirecting at command to the device file representing the modem; and I can read back the response using cat utility running on the background (started earlier). I implemented it in a script which can send a
