[英]Running a Linux command from java
I'm trying to run a command from java. 我正在尝试从java运行命令。 But command is not executing. 但命令没有执行。 Can anyone pointout why? 任何人都可以指出为什么?
String path = dest+"/info_updated.csv";
File file = new File(path);
String command = "sed -i '/" + subscriberId + "/d' "+file;
System.out.println("command "+command);
Runtime run = Runtime.getRuntime();
Process p = null;
try {
p = run.exec(command);
InputStream errorStream = p.getErrorStream();
p.waitFor();
} catch (IOException ioe) {
ioe.printStackTrace();
System.out.println("ERROR.RUNNING.CMD");
} catch (Exception e) {
e.printStackTrace();
} finally {
p.destroy();
}
return true;
}
In the log it is printing the command correctly. 在日志中,它正确地打印命令。
command sed -i '/L13876110226750000/d' /usr/share/apache-tomcat-6.0.37/webapps/SMS/info_updated.csv
But it is not executing. 但它没有执行。
You could add /bin/sh -c
before your command and have a try. 您可以在命令之前添加/bin/sh -c
并尝试一下。
Like this: 像这样:
String[] command = {"/bin/sh", "-c", "sed -i '/" + subscriberId + "/d' "+file};
Process p = run.exec(command);
