Hello techedipro,

Which AIX version are you running? It might make a difference.

Are these conditions to be AND-ed together or OR-ed together? Please be specific else we might go the wrong way about this. As RudiC mentions, it would be better to know what to positively look for rather than try to strip out the unwanted.

Perhaps (depending on the size of the file list being processed) you could use these tests to build a list of files that you want to exclude and then use something like grep -vfF remove_these main_file_list > wanted_file_list to get you close, but if the remove list gets large then results can be less predictable and slow. It would cost processing and IO to go this long way round, but it's possible if there is not better logic to positively select what you want to report.

The easiest way to get your actual output file when you have a list of names may be something like:-

Code:

awk 'BEGIN {print "<Files>"} ; {print "<FileName>"$0"</FileName>"} ; END {print "</Files>"} ' wanted_file_list  >  output_file

Of course, there may be a better way to blend it into a single operation, saving the processing and IO cost, but you need to help us understand the context. Some examples would be good.

I hope that this helps,
Robin

MatchEditor(3I) 					    InterViews Reference Manual 					   MatchEditor(3I)

NAME

       MatchEditor - StringEditor with pattern matching

SYNOPSIS

       #include <InterViews/matcheditor.h>

DESCRIPTION

       MatchEditor  is	a StringEditor subclass that checks the validity of its contents against a specified pattern.  It is suitable for entering
       strings that must conform to a particular format such as a number or a file name.  The matching pattern is specified according to the rules
       of  scanf(3).   For  example, a pattern of "%3d" will match a 3-digit integer, a pattern of "%[ab]" will match a string containing only a's
       and b's, and a pattern of "(%f, %f)" will match the string "(12.0, 5E23)".

PUBLIC OPERATIONS

       MatchEditor(ButtonState*, const char* sample, const char* done)
	      Create a new MatchEditor object.	The ButtonState, sample string, and termination string are passed to the StringEditor constructor.

       void Match(const char* pattern, boolean keystroke = true)
	      Specify the pattern to match against.  When MatchEditor performs matching, it will highlight any trailing part of  the  edit  string
	      that  does  not  conform to pattern.  The user can then correct the string.  If keystroke is true, matching will occur on every key-
	      stroke; otherwise matching will only occur on the completion of the edit.  The initial pattern matches any string, and  the  initial
	      value of keystroke is true.

RESTRICTIONS

       MatchEditor  uses  sscanf  internally to check the pattern match.  Different versions of sscanf have different scanning capabilities; check
       with your local version to see what patterns you can use.
