tr '\verb|\|000' '\verb|\|\n'?

[Johann Spies <jhspies@adept.co.za>]

Can somebody explain the subject line to me please.  I have read it in
a linux training document and it is not doing what the document says
it should do.  What I do not understand and do not know where to find
documentation on it is the '\verb|\|000' '\verb|\|\n' part.  I know tr
but what is '\verb|\|000'?  And the use of |\|?  

The whole command according to the document is

cat /proc/$$/environ | tr '\verb|\|000' '\verb|\|\n' 

which is supposed to put each variable it shows on a separate line.

Johann.

     "Beloved, think it not strange concerning the fiery 
      trial which is to try you, as though some strange 
      thing happened unto you; But rejoice, inasmuch as ye 
      are partakers of Christ's sufferings; that, when his 
      glory shall be revealed, ye may be glad also with 
      exceeding joy."       I Peter 4:12,13
