Top Forums UNIX for Dummies Questions & Answers problem with grep on search string in a txt file over multiple files Post 302196464 by jim mcnamara on Sunday 18th of May 2008 01:06:17 PM

A 25k long search string? Is your text so similar that you need to search 25000 characters to be sure of a match. Assuming the regex engine can even deal with that, the search efficiency is going to be pretty poor.

Or do you mean 25000 different strings? That has problems as well.

I think, rather than you tell us how you think it should be done, give us the problem you are trying to solve - in detail. This whole thing sounds wrong from the start, as I read it.

There are a lot of other tools out there like comm for example.

XmTextFindStringWcs -- A Text function that finds the beginning position of a wide character text string SYNOPSIS
#include <Xm/Text.h> Boolean XmTextFindStringWcs( Widget widget, XmTextPosition start, wchar_t *wcstring, XmTextDirection direction, XmTextPosition *position); DESCRIPTION
XmTextFindStringWcs locates the beginning position of a specified wide character text string. This routine searches forward or backward for the first occurrence of the string, starting from the given start position. If a match is found, the function returns the position of the first character of the string in position. If the match string begins at the current position, this routine returns the current position. widget Specifies the Text widget ID. start Specifies the character position from which the search proceeds. This is an integer number of characters from the beginning of the text buffer. The first character position is 0 (zero). wcstring Specifies the wide character search string. direction Indicates the search direction. It is relative to the primary direction of the text. The possible values are XmTEXT_FORWARD The search proceeds toward the end of the buffer. XmTEXT_BACKWARD The search proceeds toward the beginning of the buffer. position Specifies the pointer in which the first character position of the string match is returned. This is an integer number of char- acters from the beginning of the buffer. The first character position is 0 (zero). If the function returns False, this value is undefined. For a complete definition of Text and its associated resources, see XmText(3). RETURN
