# Shell implements an idiomatic Ruby interface for common UNIX shell commands.
#
# It provides users the ability to execute commands with filters and pipes,
# like +sh+/+csh+ by using native facilities of Ruby.
#
# == Examples
#
# === Temp file creation
#
# In this example we will create three +tmpFile+'s in three different folders
# under the +/tmp+ directory.
#
#   sh = Shell.cd("/tmp") # Change to the /tmp directory
#   sh.mkdir "shell-test-1" unless sh.exists?("shell-test-1")
#   # make the 'shell-test-1' directory if it doesn't already exist
#   sh.cd("shell-test-1") # Change to the /tmp/shell-test-1 directory
#   for dir in ["dir1", "dir3", "dir5"]
#     if !sh.exists?(dir)
#       sh.mkdir dir # make dir if it doesn't already exist
#       sh.cd(dir) do
#         # change to the `dir` directory
# 	  f = sh.open("tmpFile", "w") # open a new file in write mode
# 	  f.print "TEST\n"            # write to the file
# 	  f.close                     # close the file handler
#       end
#       print sh.pwd                  # output the process working directory
#     end
#   end
#
# === Temp file creation with self
#
# This example is identical to the first, except we're using
# CommandProcessor#transact.
#
# CommandProcessor#transact executes the given block against self, in this case
# +sh+; our Shell object. Within the block we can substitute +sh.cd+ to +cd+,
# because the scope within the block uses +sh+ already.
#
#   sh = Shell.cd("/tmp")
#   sh.transact do
#     mkdir "shell-test-1" unless exists?("shell-test-1")
#     cd("shell-test-1")
#     for dir in ["dir1", "dir3", "dir5"]
#       if !exists?(dir)
# 	  mkdir dir
# 	  cd(dir) do
# 	    f = open("tmpFile", "w")
# 	    f.print "TEST\n"
# 	    f.close
# 	  end
# 	  print pwd
#       end
#     end
#   end
#
# === Pipe /etc/printcap into a file
#
# In this example we will read the operating system file +/etc/printcap+,
# generated by +cupsd+, and then output it to a new file relative to the +pwd+
# of +sh+.
#
#   sh = Shell.new
#   sh.cat("/etc/printcap") | sh.tee("tee1") > "tee2"
#   (sh.cat < "/etc/printcap") | sh.tee("tee11") > "tee12"
#   sh.cat("/etc/printcap") | sh.tee("tee1") >> "tee2"
#   (sh.cat < "/etc/printcap") | sh.tee("tee11") >> "tee12"
