Top Forums Shell Programming and Scripting Delete lines in file containing duplicate strings, keeping longer strings Post 302556131 by raidzero on Friday 16th of September 2011 05:29:45 PM

The string lengths can vary a lot. Actually it causes issues with long strings, it creates new lines in the file, which doesn't fly.

new lines in the strings is what I meant*

here is an example string that gets mangled:

Code:
%1$s\n\nFrom: %2$s\n\nTo: %3$s

---------- Post updated at 05:11 PM ---------- Previous update was at 05:04 PM ----------

and the reason it is mangled is because of those newline characters in the string... the awk script interprets the newlines when in fact the newline is not supposed to show up until application runtime Smilie

ignoring the "\n"'s would be ideal, can that be done? I don't really understand any of your function...

I got around the newline thing with sed: sed -i -e 's/\\/\\\\/g'

wstring(3C)						   Standard C Library Functions 					       wstring(3C)

NAME
wstring, wscasecmp, wsncasecmp, wsdup, wscol - Process Code string operations SYNOPSIS
#include <widec.h> int wscasecmp(const wchar_t *s1, const wchar_t *s2); int wsncasecmp(const wchar_t *s1, const wchar_t *s2, int n); wchar_t *wsdup(const wchar_t *s); int wscol(const wchar_t *s); DESCRIPTION
These functions operate on Process Code strings terminated by wchar_t null characters. During appending or copying, these routines do not check for an overflow condition of the receiving string. In the following, s, s1, and s2 point to Process Code strings terminated by a wchar_t null. wscasecmp(), wsncasecmp() The wscasecmp() function compares its arguments, ignoring case, and returns an integer greater than, equal to, or less than 0, depending upon whether s1 is lexicographically greater than, equal to, or less than s2. It makes the same comparison but compares at most n Process Code characters. The four Extended Unix Code (EUC) codesets are ordered from lowest to highest as 0, 2, 3, 1 when characters from different codesets are compared. wsdup() The wsdup() function returns a pointer to a new Process Code string, which is a duplicate of the string pointed to by s. The space for the new string is obtained using malloc(3C). If the new string cannot be created, a null pointer is returned. wscol() The wscol() function returns the screen display width (in columns) of the Process Code string s. ATTRIBUTES
