We can also interpolate Ruby code directly into the shell by
using the normal `#{}` string interpolation syntax.
In the code below we're going to switch to `shell-mode` and use the
`gem-cd` command to enter the home directory for a gem and examine
some of the files there, we will also show off some interpolation.
some of the files there:
pry(main)> shell-mode
pry main:/home/john/ruby/projects/pry $ .ls
bin CHANGELOG examples lib LICENSE pkg Rakefile README.markdown TAGS test TODO wiki
pry main:/home/john/ruby/projects/pry $ gem-cd yard
pry main:/home/john/.rvm/gems/ruby-1.9.2-head/gems/yard-0.6.4 $ .ls
benchmarks bin ChangeLog docs LEGAL lib LICENSE Rakefile README.md spec templates
pry main:/home/john/.rvm/gems/ruby-1.9.2-head/gems/yard-0.6.4 $ .cd lib
=> /home/john/.rvm/gems/ruby-1.9.2-head/gems/yard-0.6.4/lib
pry main:/home/john/.rvm/gems/ruby-1.9.2-head/gems/yard-0.6.4/lib $ .ls

We can also interpolate Ruby code into the Shell commands. In the
example below we use the shell command `cat` on a random file from the
current directory and count the number of lines in that file with
`wc`:
pry main:/home/john/.rvm/gems/ruby-1.9.2-head/gems/yard-0.6.4/lib $ .cat #{Dir['*.*'].sample} | wc -l
