man 5 crontab says:
[..]
       The ``sixth'' field (the rest of the line) specifies the command 
to  be
       run.   The  entire  command  portion  of the line, up to a 
newline or %
       character, will be executed by /bin/sh or by the shell specified 
in the
       SHELL  variable of the cronfile.  Percent-signs (%) in the 
command, un‐
       less escaped with backslash (\), will be changed into  newline  
charac‐
       ters,  and  all  data  after the first % will be sent to the 
command as
       standard input.

Regards,

Leigh.
