For example, if you are redirecting a shell script ! 17: to a file and someone sends you a message, that message will land ! 18: in your file. Therefore, COHERENT supplies the command mesg, ! 19: which, lets you permit or suppress messages from other users. ! 20: The argument y allows messages, whereas argument n disallows mes- ! 21: sages. With no argument, mesg tells you whether you can receive ! 22: messages (as yes or no) without changing the message state. ! 23: ! 24: ***** Files ***** ! 25: ! 26: /dev/* ! 27: ! 28: ***** See Also ***** ! 29: ! 30: commands, msg, write ! 31: ! 32: ***** Notes ***** ! 33: ! 34: The owner-execute mode bit of the user's tty indicates whether ! 35: messages are allowed. ! 36: ! 37: ! 38: ! 39: ! 40: ! 41: ! 42: ! 43: ! 44: ! 45: ! 46: ! 47: ! 48: ! 49: ! 50: ! 51: ! 52: ! 53: ! 54: ! 55: ! 56: ! 57: ! 58: ! 59: ! 60: ! 61: ! 62: ! 63: ! 64: COHERENT Lexicon Page 1 ! 65: ! 66:
