I recently netposted my approach to providing an "executable prompt" for csh, as well as a request for some inside info on csh. I no longer need this info, because I have successfully modified cshell to provide me with an arbitrary preprompt execution. With this, I have been able to put the time of day, the current directory, or any other command sequence, into my prompt (i.e. just prior to printing my prompt, my csh executes the command, if any, that it finds in the shell variable "preprompt".) There is potential for abuse (such as setting that variable to a value which immediately causes an infinite cascade of csh processes), but so far I have had no problems. I won't netpost or distribute the source, as the csh on which my modification is based is surely licensed. However, I will (after a sufficient test period) mail anyone interested a copy of my two small added routines and the single call that invokes them (along with directions on where to put them). (Unless I learn of some reason not to.) --dmy-- (David Yablon, decvax!harpo!seismo!dmy, No.Vi., 83/1/18)
