I have requirement of parsing file names from given directory based on the pattern ( pattern will be parameter to script and can be any ).
for example, user enterred 2 params :
1) directory name : /dirname/
2) filename_pattern : *.dat_????
and there are 2 files in the directory as :
now I need to parse and retrive filename with static portion :
result :
1) a.dat_
2) b.dat_
Can you please give some pointers to solution, what are the ways this can be implemented.
Thanks in advance ...
Thanks

I don't understand what you're trying to do. The only static data matched by the pattern *.dat_???? is .dat_. The 1st character of each filename is matched by the asterisk in the pattern and the 4 characters at the end of each filename is matched by the question marks.

Hi, I have 2 files that I have modified to basically match each other, however I want to determine what (if any) line in file 1 does not exist in file 2. I need to match column $1 and $2 as a single string in file1 to $1 and $2 in file2 as these two columns create a match.

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
