Dear wise monks,

I have a unix shell which will launch an interacive tool (with its own interactive shell/prompt) and another unix shell which will launch a Tcl shell (prompt). This means that there are 2 processes running on 2 unix shells.
What I want is that there should be a socket communication between these 2 processes, with the Tcl shell as the master of the two. Any command on the Tcl shell will be checked for error and then executed either on its own shell or on the other (tool) shell over the socket link.
Can you please provide me pointers as to how I can achieve the above (if possible, optimally)?

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
