I can't for the love of me figure out how to work with double quotes and single quotes in variables in bash scripts. For instance, I added the following line to my .bash_aliases file:
I want this so that I can go straight to 'My Documents' in my Windows installation (which is mounted at /host) by using cd in the terminal. This is my issue though:
What do I have to change the code in .bash_aliases to to make this work? Also, if you know of any good sites that explain this sort of thing, that would be great.
I have a script that I'm trying to shorten (below) by removing repetitive code.

Sometimes it is handy to protect long scripts in C++.
The following syntax works fine for simple commands:
#define SHELLSCRIPT1 "\
#/bin/bash \n\
echo \"hello\" \n\

cout <<system(SHELLSCRIPT1);
return 0;

Perl::Critic::Policy::Variables::ProhibitPerl4PackageNamUserpContributed Perl DocumPerl::Critic::Policy::Variables::ProhibitPerl4PackageNames(3pm)NAME
Perl::Critic::Policy::Variables::ProhibitPerl4PackageNames - Use double colon (::) to separate package name components instead of single
quotes (').
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
Perl 5 kept single quotes ("'") as package component separators in order to remain backward compatible with prior "perl"s, but advocated
using double colon ("::") instead. In the more than a decade since Perl 5, double colons have been overwhelmingly adopted and most people
are not even aware that the single quote can be used in this manner. So, unless you're trying to obfuscate your code, don't use them.
package Foo::Bar::Baz; #ok
package Foo'Bar'Baz; #not ok
CONFIGURATION
This Policy is not configurable except for the standard options.
