Method: Net::SFTP::Operations::Dir#glob
- Defined in:
- lib/net/sftp/operations/dir.rb
#glob(path, pattern, flags = 0) ⇒ Object
Works as ::Dir.glob, matching (possibly recursively) all directory entries under path
against pattern
. If a block is given, matches will be yielded to the block as they are found; otherwise, they will be returned in an array when the method finishes.
Because working over an SFTP connection is always going to be slower than working purely locally, don’t expect this method to perform with the same level of alacrity that ::Dir.glob does; it will work best for shallow directory hierarchies with relatively few directories, though it should be able to handle modest numbers of files in each directory.
