Echo eval xargs and other siblings

It always seemed to me that these utils are siblings.
All they do are that substitute values for variables, rearrange the parameters, and confuse the input with the output. Smilie
I tried to display their main signature in table together. To show their similarities

NAME
psbook - rearrange pages in PostScript file into signatures SYNOPSIS
psbook [ -q ] [ -ssignature ] [ infile [ outfile ] ] DESCRIPTION
Psbook rearranges pages from a PostScript document into ``signatures'' for printing books or booklets, creating a new PostScript file. The input PostScript file should follow the Adobe Document Structuring Conventions. The -s option selects the size of signature which will be used. The signature size is the number of sides which will be folded and bound together; the number given should be a multiple of four. The default is to use one signature for the whole file. Extra blank sides will be added if the file does not contain a multiple of four pages. Psbook normally prints the page numbers of the pages rearranged; the -q option suppresses this. AUTHOR
