DESCRIPTION

FUNCTIONS

list_common_files

Usage:

 list_common_files(%args) -> any

List files that are found in {all,more than one} directories.

This routine lists files that are found in all specified directories (or, when min_occurrences option is specified, files that are found in at least a certain number of occurrences. Note that only filenames are compared, not content/checksum. Directories are excluded.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

  • detail => bool

    Whether to return detailed result per file.

    If set to true, instead of an array of filenames:

     ["file1", "file2"]

    it will instead return a hash with filename as key and another hash containing detailed information:

     {
         "file1" => {
             dirs => ["dir1", "dir2"], # in which dirs the file is found
         },
         "file2" => {
             ...
         },
     }
  • dirs* => array[dirname]

  • min_occurrence => posint

Return value: (any)
