Trying to create a symbolic link will fail if the name of the symlink to be created already exists. Try this instead:

Code:

#!/bin/ksh
################################################################################
#
# Create Desktop shortcut for Swedish Menu Commands Document
#
################################################################################
swedishKeyboardDocPath1="$APPSUPPORT_PATH/Finale Extra/PrintMusic 2014 Menykommandon.pdf"
swedishKeyboardShortcut1=~"/Desktop/PrintMusic 2014 Menykommandon.pdf"
if [ -e "$swedishKeyboardDocPath1" ]
then	rm -f "$swedishKeyboardShortcut1"
	ln -s "$swedishKeyboardDocPath1" "$swedishKeyboardShortcut1"
else	printf '%s: "%s" not found.\n' "${0##*/}" "$swedishKeyboardDocPath1"
	exit 1
fi

Note, however, that this will not work unless APPSUPPORT_PATH is an exported variable in your environment when you invoke this script.

Sub::Install(3) User Contributed Perl Documentation Sub::Install(3) NAME
Sub::Install - install subroutines into packages easily VERSION
version 0.926 SYNOPSIS
use Sub::Install; Sub::Install::install_sub({ code => sub { ... }, into => $package, as => $subname }); DESCRIPTION
This module makes it easy to install subroutines into packages without the unslightly mess of "no strict" or typeglobs lying about where just anyone can see them. FUNCTIONS
install_sub Sub::Install::install_sub({ code => &subroutine, into => "Finance::Shady", as => 'launder', }); This routine installs a given code reference into a package as a normal subroutine. The above is equivalent to: no strict 'refs'; *{"Finance::Shady" . '::' . "launder"} = &subroutine; If "into" is not given, the sub is installed into the calling package. If "code" is not a code reference, it is looked for as an existing sub in the package named in the "from" parameter. If "from" is not given, it will look in the calling package. If "as" is not given, and if "code" is a name, "as" will default to "code". If "as" is not given, but if "code" is a code ref, Sub::Install will try to find the name of the given code ref and use that as "as". That means that this code: Sub::Install::install_sub({ code => 'twitch', from => 'Person::InPain', into => 'Person::Teenager', as => 'dance', }); is the same as: package Person::Teenager; Sub::Install::install_sub({ code => Person::InPain->can('twitch'), as => 'dance', }); reinstall_sub This routine behaves exactly like "install_sub", but does not emit a warning if warnings are on and the destination is already defined. install_installers This routine is provided to allow Sub::Install compatibility with Sub::Installer. It installs "install_sub" and "reinstall_sub" methods into the package named by its argument. Sub::Install::install_installers('Code::Builder'); # just for us, please Code::Builder->install_sub({ name => $code_ref }); Sub::Install::install_installers('UNIVERSAL'); # feeling lucky, punk? Anything::At::All->install_sub({ name => $code_ref }); The installed installers are similar, but not identical, to those provided by Sub::Installer. They accept a single hash as an argument. The key/value pairs are used as the "as" and "code" parameters to the "install_sub" routine detailed above. The package name on which the method is called is used as the "into" parameter. Unlike Sub::Installer's "install_sub" will not eval strings into code, but will look for named code in the calling package. EXPORTS
Sub::Install exports "install_sub" and "reinstall_sub" only if they are requested. exporter Sub::Install has a never-exported subroutine called "exporter", which is used to implement its "import" routine. It takes a hashref of named arguments, only one of which is currently recognize: "exports". This must be an arrayref of subroutines to offer for export. This routine is mainly for Sub::Install's own consumption. Instead, consider Sub::Exporter. SEE ALSO
Sub::Installer This module is (obviously) a reaction to Damian Conway's Sub::Installer, which does the same thing, but does it by getting its greasy fingers all over UNIVERSAL. I was really happy about the idea of making the installation of coderefs less ugly, but I couldn't bring myself to replace the ugliness of typeglobs and loosened strictures with the ugliness of UNIVERSAL methods. Sub::Exporter This is a complete Exporter.pm replacement, built atop Sub::Install. AUTHOR
