Perl Shell

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Perl Shell (psh) is a command line environment that can be used as the user's primary post-login shell on Unix-like operating systems. Being itself written in Perl, psh can also be used under Microsoft Windows (with or without Cygwin or Interix) and other operating systems. Perl Shell combines aspects of bash (and other Unix shells) with the power of Perl scripting.
