| One of the Linux command line tools I had initially under-estimated is netcat or just nc. By default, netcat creates a TCP socket either in listening mode (server socket) or a socket that is used in order to connect to a server (client mode). Actually, netcat does not care whether the socket is meant to be a server or a client. All it does is to take the data from stdin and transfer it to the other end across the network. | |
| The simplest example of its usage is to create a server-client chat system. Although this is a very primitive way to chat, it shows how netcat works. In the following examples it is assumed that the machine that creates the listening socket (server) has the 192.168.0.1 IP address. So, create the chat server on this machine and set it to listen to 3333 TCP port: | |
| $ nc -l 3333 | |
| On the other end, connect to the server with the following: |
| #include <glob.h> | |
| #include <vector> | |
| #include <string> | |
| inline std::vector<std::string> glob(const std::string& pat){ | |
| using namespace std; | |
| glob_t glob_result; | |
| glob(pat.c_str(),GLOB_TILDE,NULL,&glob_result); | |
| vector<string> ret; | |
| for(unsigned int i=0;i<glob_result.gl_pathc;++i){ | |
| ret.push_back(string(glob_result.gl_pathv[i])); |
| // Use Gists to store code you would like to remember later on | |
| console.log(window); // log the "window" object to the console |
| #!/bin/bash | |

Basically, you need to open domain.xml under WILDFLY_HOME/domain/configuration and find the <deployments> session. In that session, each deployment contain a <content> tag. The attribute sha1 contains details where the file is storaged on the filesystem. EG:
<deployments>
