SHARYANTO::File::Util - File-related utilities
use SHARYANTO::File::Util qw(file_exists l_abs_path dir_empty); print "file exists" if file_exists("/path/to/file/or/dir"); print "absolute path = ", l_abs_path("foo"); print "dir exists and is empty" if dir_empty("/path/to/dir");
None are exported by default, but they are exportable. file_exists($path) => BOOL This routine is just like the -e test, except that it assume symlinks with non-existent target as existing. If "sym" is a symlink to a non-existing target: -e "sym" # false, Perl performs stat() which follows symlink but: -l "sym" # true, Perl performs lstat() -e _ # false This function performs the following test: !(-l "sym") && (-e _) || (-l _) l_abs_path($path) => STR Just like Cwd::abs_path(), except that it will not follow symlink if $path is symlink (but it will follow symlinks for the parent paths). Example: use Cwd qw(getcwd abs_path); say getcwd(); # /home/steven # s is a symlink to /tmp/foo say abs_path("s"); # /tmp/foo say l_abs_path("s"); # /home/steven/s # s2 is a symlink to /tmp say abs_path("s2/foo"); # /tmp/foo say l_abs_path("s2/foo"); # /tmp/foo Mnemonic: l_abs_path -> abs_path is analogous to lstat -> stat. Note: currently uses hardcoded "/" as path separator. dir_empty($dir) => BOOL Will return true if $dir exists and is empty. None are exported by default, but they are exportable.
Where is file_empty()? For checking if some path exists, is a regular file, and is empty (content is zero- length), you can simply use the "-z" filetest operator.
