Q connection

WebSocket Close .z.wc¶Introduced in q3.3, the system variable .z.wc can be assigned a handler that is called when a WebSocket connection is closed. Prior to q3.3 this was handled in .z.pc.Your handler is executed immediately after a WebSocket connection has been closed. Since the connection has been closed by the time the handler is called, there are no valid remote values for .z.a, .z.u or .z.w. Consequently the local values are returned.This is useful to clean up things like a table of users keyed by handle, in which case you use the just-closed handle that is passed as a parameter to .z.wc.13.3.39 On WebSocket Open .z.wo¶Introduced in q3.3, the system variable .z.wo can be assigned a handler that is called when a WebSocket connection is opened. Prior to q3.3 this was handled in .z.po.Your handler is executed just after a WebSocket connection to a kdb+ session has been initialized – i.e., once it has been validated against a -u/-U file (if specified) and .z.pw checks. The argument is the just-opened handle.This handler is typically used to build a dictionary of handles associated with session information such as .z.a or .z.u.13.3.40 On WebSocket Message .z.ws¶Assign a function to the system variable .z.ws to be evaluated whenever a message arrives over a WebSocket. See §11.7 for examples.13.3.41 Command-Line Parameters .z.x¶The system variable .z.x is a list of strings representing the command-line parameters provided after the name of the file or directory on the command-line invocation of the q process. For example, if q is invoked from the OS console with,q convertargs.q 42 forty 2.0we find,q).z.f`convertargs.qq).z.x("42";"forty";"2.0")13.3.42 Raw Command Line .z.X¶The system variable .z.X was introduced in q3.3. It is a string representing the unprocessed command line that invoked the q process, beginning with the invocation of q. For example,$rlwrap m32/q trade.q -p 12345

So scp -q file host:file and scp -q host:file file are both quiet, i.e. don't give the progress meter. But when I run scp -q host1:file host2:file, I still get the progress meter as well as a Connection to host1 closed. message. The progress meter can be gotten rid of by redirected stdout to /dev/null (although I'd rather not have to), but the connection closed messages comes on stderr, which I definitely want to keep in case there's a real error. How can I make scp quiet? Do I have to run ssh host1 "scp -q file host2:file"? asked Nov 16, 2012 at 21:33 in host1, edit ~/.ssh/config and add something like thisHost host2 LogLevel=QUIETthis will turn the messages off for you.because -q only controls the ssh client connection from your localhost, not from host1. answered Nov 16, 2012 at 22:37 2 You must log in to answer this question.
