I think what I'm trying to do is pretty straightforward but I just can't find a way to do it.
I'm trying to run a double pattern match in a three column file. If the first two columns match, I need to output the third.
So in the file
If the pattern match 'BBB' && 'CCC' is run, the output if '5'. Only one line in the file could ever match the precise pattern.
So far straightforward. But if no single line matches the pattern, I need it to output 'NaN' or something to indicate that there is no pattern in the file.
So the output is always a single line, either '5' or 'NaN'.
Conceptually this seems straightforward but I can't get it to work or find an example where you can generate a simple one-line output.
Thank you for any help

Task is to identify files like code.1 , code.23 and so on ... (the files which are ending with a number) but it should not match files like code.123abc. So the search will normally search for files with "code." and at the end we should extract for the correct match. Now I have to remove these files... (6 Replies)

tcl_stringcasematch
Tcl_StringMatch(3) Tcl Library Procedures Tcl_StringMatch(3)__________________________________________________________________________________________________________________________________________________NAME
Tcl_StringMatch, Tcl_StringCaseMatch - test whether a string matches a pattern
SYNOPSIS
#include <tcl.h>
int
Tcl_StringMatch(str, pattern)
int
Tcl_StringCaseMatch(str, pattern, flags)
ARGUMENTS
const char *str (in) String to test.
const char *pattern (in) Pattern to match against string. May contain special characters from the set *?[].
int flags (in) OR-ed combination of match flags, currently only TCL_MATCH_NOCASE. 0 specifies a case-sensitive search.
_________________________________________________________________DESCRIPTION
This utility procedure determines whether a string matches a given pattern. If it does, then Tcl_StringMatch returns 1. Otherwise
Tcl_StringMatch returns 0. The algorithm used for matching is the same algorithm used in the string match Tcl command and is similar to
the algorithm used by the C-shell for file name matching; see the Tcl manual entry for details.
In Tcl_StringCaseMatch, the algorithm is the same, but you have the option to make the matching case-insensitive. If you choose this (by
passing TCL_MATCH_NOCASE), then the string and pattern are essentially matched in the lower case.
KEYWORDS
match, pattern, string
