Top Forums Shell Programming and Scripting awk - To retrieve an expression from the last line containing a pattern Post 302913461 by Antonio Fargas on Sunday 17th of August 2014 10:33:17 AM

Thanks RudyC for your reply on this

Please find below what i'm getting keying your command :
Code:
[val@REDHAT-1 tmp]$ awk -F, 'match ($0,pattern) {T=$4} END {print T}' pattern="00527072" test
3P3

Same Result by including the pattern value directly between the brackets :
Code:
[val@REDHAT-1 tmp]$ awk -F, 'match ($0,"00527072") {T=$4} END {print T}' test3P3

It looks like awk is not returning the latest expression matching with the pattern.

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 Tcl 8.5 Tcl_StringMatch(3)
