command

In Java, how do I execute a linux program with options, like this: ls -a (the option is -a), and another: ./myscript name=john age=24 I know how to execute a command, but cannot do the option. You need to execute an external process, take a look at ProcessBuilder and just because it almost answers your question, Using ProcessBuilder to Make System Calls UPDATED with Example I ripped this straight from the list example and modified it so I could test on my PC and it runs fine private static void copy(InputStream in, OutputStream out) throws IOException { while (true) { int c = in.read(); if (c

I'm writing a maven plugin which has to initialize another java project with specific VM arguments. according to the exec:java, they only take in arguments but not VMarguments, so my question is how to launch a java project with specific VMarguments from the command line? thanks You can't supply extra VM arguments if you use Maven's exec:java plugin because it runs in the same VM (i.e. it's already been initialized). You'll need to use exec:exec, and construct the java command line yourself. 来源： https://stackoverflow.com/questions/7305090/how-to-run-a-java-project-with-vm-arguments-from

I am able to run the below powershell command through Powershell itself, invoke-command -ComputerName "compName" -filepath "c:\script.ps1" -credential "admin" but when I try running that through Java, I get an error. Sounds like "Invoke-command" is not recognized as a program to be run though Java. If this is the case, is there any other solution? Process p = new ProcessBuilder() .inheritIO() .command("invoke-command", "-computername", "compName", "-filepath", "C:\\script.ps1").start(); The error, Cannot run program "invoke-command": CreateProcess error=2, The system cannot find the file

I want to run something like cat file.tar | base64 | myprogram -c "| base64 -d | tar -zvt " I use execlp to run the process. When i try to run something like cat it works, but if i try to run base64 -d | tar -zvt it doesn't work. I looked at the bash commands and I found out that I can run bash and tell him to run other programs. So it's something like: execlp ("bash", "-c", "base64 -d | tar -zvt", NULL); If I run it on the terminal, it works well, but using the execlp it dont work. If I use execlp("cat", "cat", NULL) it works. Someone knows how to use the -c param on execlp to execute

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 = Runtime.getRuntime(); Process p=rt.exec(cmd); return p; } public void login(String password) throws

I'm not really familiar with TCSH I would like run a command2 if a command1 was entered in the shell, something like this: if command1 then echo "Command succeeded" command2 else echo "Command failed" fi I tried this code but it doesn't work. Step two would be to read and print in a file a part some variable that command1 changed (making a kind of history only for some variables). You can use $? to get exit code from last command. #!/bin/tcsh # command below can fail or succeed command1 if ( $? == 0 ) then command2 else echo "command1 failed" endif 来源： https://stackoverflow.com/questions
