Method: FileUtils.cp_lr

Defined in:
lib/fileutils.rb

.cp_lr(src, dest, noop: nil, verbose: nil, dereference_root: true, remove_destination: false) ⇒ Object

Hard link src to dest. If src is a directory, this method links all its contents recursively. If dest is a directory, links src to dest/src.

src can be a list of files.

If dereference_root is true, this method dereference tree root.

If remove_destination is true, this method removes each destination file before copy.

FileUtils.rm_r site_ruby + '/mylib', force: true
FileUtils.cp_lr 'lib/', site_ruby + '/mylib'

# Examples of linking several files to target directory.
FileUtils.cp_lr %w(mail.rb field.rb debug/), site_ruby + '/tmail'
FileUtils.cp_lr Dir.glob('*.rb'), '/home/aamine/lib/ruby', noop: true, verbose: true

# If you want to link all contents of a directory instead of the
# directory itself, c.f. src/x -> dest/x, src/y -> dest/y,
# use the following code.
FileUtils.cp_lr 'src/.', 'dest'  # cp_lr('src', 'dest') makes dest/src, but this doesn't.
