how to install perl package in cygwin for windows

In most ways it works like other Unix and Unix-like environments, but in a few key aspects it works like Windows. CygwinĬygwin provides a Unix-like environment for Microsoft Windows users. If File::Which finds such an environment variable, it parses the list and uses it as the different extensions. Usually, it will contain a list in the form. Windows NT has a special environment variable called PATHEXT, which is used by the shell to look for executable files. Modern Windows (including NT, XP, Vista, 7, 8, 10 etc) The current directory will not be searched unless it is explicitly added to the path. bat to identify them, File::Which takes extra steps to assure that you will find the correct file (so for example, you might be searching for perl, it'll try perl.exe, perl.bat, etc.) Linux, *BSD and other UNIXes Under Win32 systems, which do not have a notion of directly executable files, but uses special extensions such as. Implementationsįile::Which searches the directories of the user's PATH (the current implementation uses File::Spec#path to determine the correct PATH), looking for executable files having the name specified as a parameter to 'which'.

If you need a portable which on the command line in an environment that does not provide it, install App::pwhich which provides a command line interface to this API. As a consequence platforms where the current directory is implicitly part of the search path such as Microsoft Windows will find executables in the current directory, whereas on platforms such as UNIX where this is not the case executables in the current directory will only be found if the current directory is explicitly added to the path. The focus of this module is correctness and portability. This module provides a consistent API to this functionality regardless of the underlying platform. On some platforms, such as Microsoft Windows it is not provided as part of the core operating system. which is typically implemented as either a program or a built in shell command. This is normally the function of which utility.
