gid [OPTION]... PATTERN...
Query ID database and report results. By default, output consists
    of multiple lines, each line containing the matched identifier followed by
    the list of file names in which it occurs.
  - -f,
    --file=FILE
 
  - file name of ID database
 
  - -i,
    --ignore-case
 
  - match PATTERN case insensitively
 
  - -l, --literal
 
  - match PATTERN as a literal string

  - match PATTERN as a regular expression
 
  - -w, --word

  - -s,
    --substring
