I'm trying to execute the following command using Java

Process acquirInterfaces = Runtime.getRuntime().exec("dumpcap -D");

and getting error as

java.io.IOException: Cannot run program "dumpcap": java.io.IOException: error=2, No such file or directory

Linux box where im executing this command has got installed with dumpcap which is located under (/usr/local/bin)

Use the following line, with exact path:\n\nProcess acquirInterfaces = Runtime.getRuntime().exec(\"/usr/local/bin/dumpcap -D\");\n",

Then try\n\nProcess acquirInterfaces = Runtime.getRuntime().exec(\"/usr/local/bin/dumpcap -D\");\n\n\nAnd in case you have any problem with the slash, use File.separator:\n\nProcess acquirInterfaces = Runtime.getRuntime().exec(File.separator + \"usr\" + File.separator + \"local\" + File.separator + \"bin\" + File.separator + \"dumpcap -D\");\n",
