 print "absolute path = ", l_abs_path("foo");
 print "dir exists and is empty" if dir_empty("/path/to/dir");

DESCRIPTION

FUNCTIONS

None are exported by default, but they are exportable.

file_exists

Usage:

 file_exists($path) => BOOL

This routine is just like the -e test, except that it assume symlinks with non-existent target as existing. If sym is a symlink to a non-existing target:

 -e "sym"             # false, Perl performs stat() which follows symlink

but:

 -l "sym"             # true, Perl performs lstat()
 -e _                 # false

This function performs the following test:

 !(-l "sym") && (-e _) || (-l _)

l_abs_path

Usage:

 l_abs_path($path) => STR

Just like Cwd::abs_path(), except that it will not follow symlink if $path is symlink (but it will follow symlinks for the parent paths).

Example:

 use Cwd qw(getcwd abs_path);

 say getcwd();              # /home/steven
 # s is a symlink to /tmp/foo
 say abs_path("s");         # /tmp/foo
 say l_abs_path("s");       # /home/steven/s
 # s2 is a symlink to /tmp
 say abs_path("s2/foo");    # /tmp/foo
 say l_abs_path("s2/foo");  # /tmp/foo

Mnemonic: l_abs_path -> abs_path is analogous to lstat -> stat.

Note: currently uses hardcoded / as path separator.

dir_empty

Usage:

 dir_empty($dir) => BOOL

Will return true if $dir exists and is empty.

This should be trivial but alas it is not. -s always returns true (in other words, -z always returns false) for a directory.

dir_has_files

Usage:

 dir_has_files($dir) => BOOL

Will return true if $dir exists and has one or more plain files in it. A plain file is one that passes Perl's -f operator. A symlink to a plain file counts as a plain file. Non-plain files include named pipes, Unix sockets, and block/character special files.

dir_has_dot_files

Usage:

 dir_has_dot_files($dir) => BOOL

Will return true if $dir exists and has one or more plain dot files in it. See "dir_has_files" for the definition of plain files. Dot files a.k.a. hidden files are files with names beginning with a dot.

dir_has_non_dot_files

Usage:

 dir_has_non_dot_files($dir) => BOOL

Will return true if $dir exists and has one or more plain non-dot files in it. See "dir_has_dot_files" for the definitions. =head2 dir_has_subdirs

dir_has_subdirs

Usage:

 dir_has_files($dir) => BOOL

Will return true if $dir exists and has one or more subdirectories in it.

dir_has_dot_subdirs

Usage:

 dir_has_dot_subdirs($dir) => BOOL

Will return true if $dir exists and has one or more dot subdirectories (i.e. subdirectories with names beginning with a dot) in it.

dir_has_non_dot_subdirs

Usage:

 dir_has_non_dot_subdirs($dir) => BOOL

Will return true if $dir exists and has one or more non-dot subdirectories (i.e. subdirectories with names not beginning with a dot) in it.

FAQ

Where is file_empty()?

For checking if some path exists, is a plain file, and is empty (content is zero-length), you can simply use the -z filetest operator.
