Creating a Shortcut in a User Driectory

One correct way to communicatin is to say 'create a link'. There are two primary kinds of links, hard links and symbolic links. Directories are normally linked by symbolic links; files by hard links, but not always and YMMV. For example:
Your mail spool directory (located at /usr/spool/mail for example) is always full of big files and filling up your disk partition. You go out to ebay and purchase a 60GB drive for $100 bucks from SuperHardDisks.com. You pay with Paypal and it ships the same day
When it arrives, you have a spare slave port on one of your EIDE channels, so you power down and add the slave device and reboot. The drive is recognized by the BIOS (yippie!), so you run FDISK and create one big 60GB partition (because you get a lot of mail, mostly from spammers offering the fountain of youth and freedom from worries forever!!!).
You then create a directory (normally in the root partition) and then mount the new partition, call it (/usr/spool/supermaildisk). Then you shutdown your mail daemon and move all the mail in /usr/spool/mail to /usr/spool/supermaildisk. Then you remove the /usr/spool/mail directory and create a new symbolic link from /usr/spool/supermail to /usr/spool/mail.
You test to make sure you did not fat-finger any commands and make some goofy error, restart your mail daemon and 'poof!!', you just increased your mail spool directory to many GB.
Perhaps someone else will explain hard links and files, how to use symbolic links for library files, and other exciting fun with links

image::exiftool::shortcuts
Image::ExifTool::Shortcuts(3pm) User Contributed Perl Documentation Image::ExifTool::Shortcuts(3pm) NAME
Image::ExifTool::Shortcuts - ExifTool shortcut tags SYNOPSIS
This module is required by Image::ExifTool. DESCRIPTION
This module contains definitions for tag name shortcuts used by Image::ExifTool. You can customize this file to add your own shortcuts. Individual users may also add their own shortcuts to the .ExifTool_config file in their home directory (or the directory specified by the EXIFTOOL_HOME environment variable). The shortcuts are defined in a hash called %Image::ExifTool::UserDefined::Shortcuts. The keys of the hash are the shortcut names, and the elements are either tag names or references to lists of tag names. An example shortcut definition in .ExifTool_config: %Image::ExifTool::UserDefined::Shortcuts = ( MyShortcut => ['createdate','exif:exposuretime','aperture'], MyAlias => 'FocalLengthIn35mmFormat', ); In this example, MyShortcut is a shortcut for the CreateDate, EXIF:ExposureTime and Aperture tags, and MyAlias is a shortcut for FocalLengthIn35mmFormat.
