Hi cfajohnson,

Yes I was thinking about doing that. However, the pattern that I would like to match is condition dependent. I would like to do something like this:

Code:
if [ $START_LEVEL = 0 ]; then
        PATTERN_ARRAY=('[AT]*.L0_LAC' 'MOD00.[AP]*.PDS')
elif [ $START_LEVEL = 1 ]; then
        PATTERN_ARRAY=([AST]*.L1A_[GL]AC* S*.L1A_MLAC*)
elif [ $START_LEVEL = 2 ]; then
        PATTERN_ARRAY=([AST]*.L2_[GL]AC* S*.L2_MLAC*)
elif [ $START_LEVEL = 3 ]; then
        PATTERN_ARRAY=([AST]*_*_*.L3)
fi

for ENTRY in *; do
     for PATTERN in ${PATTERN_ARRAY[@]}; do
          case $ENTRY in
               $PATTERN)
               echo 'Entry matches pattern'
               ;;
               *)
               echo 'Entry does NOT match pattern'
               ;;
          esac
     done
done

However, the shell appears to be performing the pattern matching in if statements. Is there a way to get around that? Thank you.

Mike

tcl_stringmatch

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
