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

fc-pattern

FC-PATTERN(1)                                                                                                                        FC-PATTERN(1)

NAME

       fc-pattern - parse and show pattern

SYNOPSIS

       fc-pattern [ -cdVh ] [ --config ] [ --default ] [ -f format | --format format ] [ --version ] [ --help ]
           [ pattern  [ element ... ]  ]

DESCRIPTION

       fc-pattern  parses  pattern (empty pattern by default) and shows the parsed result.  If --config is given, config substitution is performed
       on the pattern before being displayed.  If --default is given, default substitution is performed on the pattern before being displayed.

       If any elements are specified, only those are printed.

OPTIONS

       This program follows the usual GNU command line syntax, with long options starting with two dashes (`-').  A summary of options is included
       below.

       -c --config
              Perform config substitution on pattern.

       -d --default
              Perform default substitution on pattern.

       -f --format format
              Format output according to the format specifier format.

       -V --version
              Show version of the program and exit.

       -h --help
              Show summary of options.

       pattern
              Parses and displays pattern (uses empty pattern by default).

       element
              If set, the element property is displayed for parsed pattern.
