This is extended question of Howto check against zsh script's parameter in a pattern or not

While the link above solved the problem that a zsh script check agaist its first argument to list of patterns in a file separated by newline. I'd like to extend it as:

  1. Check against patterns that in multiple files in multiple folders that probably in an array of folders.

  2. Keep tracking of that matched pattern to do another task, i.e: call a .conf that setup something else.

While I ask this question, I still in multitasks and will update it later, if you have a solution, I'll much appreciated.

files=($^array_of_folders/**/*.pattern(.N)) # assuming pattern files
                                            # have a .pattern extension
pattern="($(cat -- $files | paste -sd '|' -))"
if [[ $1 = $~pattern ]]; then
   print -r -- "$1 matches $pattern"
fi

Though if you want to know which of the patterns matched, you'd need:

files=($^array_of_folders/**/*.pattern(.N))
patterns=(${(f)"$(cat -- $files)"})
matching_patterns=()
for pattern ($patterns) {
   [[ $1 = $~pattern ]] && matching_patterns+=$pattern
}
print -r -- "$1 matched by $#matching_patterns patterns: $matching_patterns"

  • What would you define array_of_folders? Something like array_of_folders=(~/fder1 ~/smt/fder2 /tmp/fder3)? Also pattern is $1 - first argument of zsh script: script.zsh my_pattern

    @TuyenPham, that array_of_folders is meant to be the array of folders you refer to in your question. And yes array_of_folders=(~/fder1 ~/smt/fder2 /tmp/fder3) could be one way to define it. In your question, you say $1 is the string to match against patterns, not a pattern. Aug 28 '18 at 15:42
  • Ah yes, correct, $1 is string to match against patterns in files that inside folders.
