SHARYANTO::File::Util - File-related utilities
This document describes version 0.57 of SHARYANTO::File::Util (from Perl distribution SHARYANTO-File-Util), released on 2014-05-17.
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.
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
-l "sym" # true, Perl performs lstat() -e _ # false
This function performs the following test:
!(-l "sym") && (-e _) || (-l _)
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).
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.
Will return true if
$dir exists and is 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.
