Test::File::ShareDir is some low level plumbing to enable a distribution to perform tests while consuming its own share directories in a manner similar to how they will be once installed.

This module reads a file backwards line by line. It is simple to use, memory efficient and fast. It supports both an object and a tied handle interface.

It is intended for processing log and other similar text files which typically have their newest entries appended to them. By default files are assumed to be plain text and have a line ending appropriate to the OS. But you can set the input record separator string on a per file basis.

The package provides two environments called filecontentsdef and filecontentshere. They are derived from the LaTeX filecontents environment. In addition to the file creation they either store the (verbatim) contents in a macro (filecontentsdef) or typeset them (verbatim) on the spot (filecontentshere). The author developed the package to display TeX code verbatim in documentation and the same time produce the corresponding files during the LaTeX run in order to embed them in the PDF as file attachment annotations (by using Scott Pakin's package attachfile).

This package provides a collection of I/O tools for handling the most commonly used genomic datafiles, like fasta/-q, bed, gff, gtf, ped/map and vcf.

File::ShareDir::Install allows you to install read-only data files from a distribution. It is a companion module to File::ShareDir, which allows you to locate these files after installation.

find-file-in-project finds files or directories quickly in the current project. The project root is detected automatically when Git, Subversion or Mercurial are used. It also provides functions to assist in reviewing changes on files.

Filesys::Notify::Simple is a simple but unified interface to get notifications of changes to a given file system path. It uses inotify2 on Linux, fsevents on OS X, kqueue on FreeBSD, and FindFirstChangeNotification on Windows if they're installed, and falls back to a full directory scan if none of these are available.

Test::Portability::Files module is used to check the portability across operating systems of the names of the files present in the distribution of a module. The tests use the advices given in 'Files and Filesystems' in perlport. The author of a distribution can select which tests to execute.

Show in File Manager is a Python package to open the system file manager and optionally select files in it. The point is not to open the files, but to select them in the file manager, thereby highlighting the files and allowing the user to quickly do something with them.
