Module Functions

require 'fileutils'

FileUtils.cd(dir, options)
FileUtils.cd(dir, options) {|dir| .... }
FileUtils.pwd()
FileUtils.mkdir(dir, options)
FileUtils.mkdir(list, options)
FileUtils.mkdir_p(dir, options)
FileUtils.mkdir_p(list, options)
FileUtils.rmdir(dir, options)
FileUtils.rmdir(list, options)
FileUtils.ln(old, new, options)
FileUtils.ln(list, destdir, options)
FileUtils.ln_s(old, new, options)
FileUtils.ln_s(list, destdir, options)
FileUtils.ln_sf(src, dest, options)
FileUtils.cp(src, dest, options)
FileUtils.cp(list, dir, options)
FileUtils.cp_r(src, dest, options)
FileUtils.cp_r(list, dir, options)
FileUtils.mv(src, dest, options)
FileUtils.mv(list, dir, options)
FileUtils.rm(list, options)
FileUtils.rm_r(list, options)
FileUtils.rm_rf(list, options)
FileUtils.install(src, dest, mode = <src's>, options)
FileUtils.chmod(mode, list, options)
FileUtils.chmod_R(mode, list, options)
FileUtils.chown(user, group, list, options)
FileUtils.chown_R(user, group, list, options)
FileUtils.touch(list, options)

The options parameter is a hash of options, taken from the list :force, :noop, :preserve, and :verbose. :noop means that no changes are made. The other two are obvious. Each method documents the options that it honours.

All methods that have the concept of a “source” file or directory can take either one file or a list of files in that argument. See the method documentation for examples.

There are some ‘low level’ methods, which do not accept any option:

FileUtils.copy_entry(src, dest, preserve = false, dereference = false)
FileUtils.copy_file(src, dest, preserve = false, dereference = true)
FileUtils.copy_stream(srcstream, deststream)
FileUtils.remove_entry(path, force = false)
FileUtils.remove_entry_secure(path, force = false)
FileUtils.remove_file(path, force = false)
FileUtils.compare_file(path_a, path_b)
FileUtils.compare_stream(stream_a, stream_b)
FileUtils.uptodate?(file, cmp_list)

module FileUtils::Verbose

This module has all methods of FileUtils module, but it outputs messages before acting. This equates to passing the :verbose flag to methods in FileUtils.

module FileUtils::NoWrite

This module has all methods of FileUtils module, but never changes files/directories. This equates to passing the :noop flag to methods in FileUtils.

module FileUtils::DryRun

This module has all methods of FileUtils module, but never changes files/directories. This equates to passing the :noop and :verbose flags to methods in FileUtils.
