7.5 Print ‘bash’ Environment
============================

This script strips the definition of the shell functions from the output
of the ‘set’ Bourne-shell command.

     #!/bin/sh

     set | sed -n '
     :x

     # if no occurrence of "=()" print and load next line
     /=()/! { p; b; }
     / () $/! { p; b; }

     # possible start of functions section
     # save the line in case this is a var like FOO="() "
     h

     # if the next line has a brace, we quit because
     # nothing comes after functions
     n
     /^{/ q

     # print the old line
     x; p

     # work on the new line now
     x; bx
