Filesys::POSIX::Userland - Provide implementations for higher-level, "userland" functionality in Filesys::POSIX
This module is a mixin imported by Filesys::POSIX into its own namespace, and provides a variety of higher-level calls to supplement the normal suite of system calls provided in Filesys::POSIX itself.
$fs->mkpath($path)
$fs->mkpath($path, $mode)
Similar to the -p flag that can be passed to mkdir(1), this method attempts to create a hierarchy of directories specified in $path. Each path component created will be made with the mode specified by $mode, if any, if a directory in that location does not already exist. Exceptions will be thrown if one of the items along the path hierarchy exists but is not a directory.
-p
$path
$mode
A default mode of 0777 is assumed; only the permissions field of $mode is used when it is specified. In both cases, the mode specified is modified with exclusive OR by the current umask value.
$fs->getcwd
Returns a string representation of the current working directory.
$fs->realpath($path)
Returns a string representation of the full, true and original path of the inode specified by $path.
Using $fs->stat, the inode of $path is resolved, then starting at that inode, each subsequent inode's name is found from its parent and appended to a list of path components.
$fs->stat
$fs->opendir($path)
Returns a newly opened directory handle for the item pointed to by $path. Using other methods in this module, the directory can be read and closed.
$fs->readdir($directory)
Read the next member of the directory passed. Returns undef if there are no more entries to be read.
$fs->closedir($directory)
Closes the directory handle for reading.
$fs->touch($path)
Acts like the userland utility touch(). Uses $fs->open with the $O_CREAT flag to open the file specified by $path, and immediately closes the file descriptor returned. This causes an update of the inode modification time for existing files, and the creation of new, empty files otherwise.
$fs->open
$O_CREAT
