Module Functions

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

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