Is this a homework assignment? Presumably the editor used is VI/VIM,etc.
The initial parameter deals with the scope.
The next deals with the action and the condition under which the action is taken.
The end entry deals with specifying options i.e. case sensitive insensitive, repeat, etc.

1,$  means from line 1 to the end of file

s means substitute

s?/lib/ ?/lib32/ ?g  means substitute all occurances of /lib/ with /lib32/
s?-q64??g means substitute all occurences of -q64 with nothing, ie: delete it
s?/lib/sysliblist?/lib32/sysliblist?g means substitute all ocurrences of /lib/syslibist with /lib32/sysliblist
