Top Forums Shell Programming and Scripting Merge two files based on a 3rd key file Post 302485912 by DGPickett on Thursday 6th of January 2011 12:52:20 PM

Seems a bit fluffy if they have serious amounts of data. I suspect 3-4 sorts, 2 joins and 1 intermediate file would do it in bulk: sort two files, join them, possibly resort the result, sort the third file, join it and the result.

With the right SQL flat file tools, you can just do it as a three way join.

__________________________________________________________________________________________________________________________________________________

NAME
Tk_GetJoinStyle, Tk_NameOfJoinStyle - translate between strings and join styles SYNOPSIS
#include <tk.h> int Tk_GetJoinStyle(interp, string, joinPtr) const char * Tk_NameOfJoinStyle(join) ARGUMENTS
Tcl_Interp *interp (in) Interpreter to use for error reporting. const char *string (in) String containing name of join style: one of "bevel", "miter", or "round". int *joinPtr (out) Pointer to location in which to store X join style corresponding to string. int join (in) Join style: one of JoinBevel, JoinMiter, JoinRound. _________________________________________________________________ DESCRIPTION
Tk_GetJoinStyle places in *joinPtr the X join style corresponding to string, which will be one of JoinBevel, JoinMiter, or JoinRound. Join styles are typically used in X graphics contexts to indicate how adjacent line segments should be joined together. See the X documentation for information on what each style implies. Under normal circumstances the return value is TCL_OK and interp is unused. If string does not contain a valid join style or an abbrevia- tion of one of these names, then an error message is stored in interp->result, TCL_ERROR is returned, and *joinPtr is unmodified. Tk_NameOfJoinStyle is the logical inverse of Tk_GetJoinStyle. Given a join style such as JoinBevel it returns a statically-allocated string corresponding to join. If join is not a legal join style, then "unknown join style" is returned. KEYWORDS
bevel, join style, miter, round Tk Tk_GetJoinStyle(3)
