with the command `hostname` you are searching for the output of the command hostname in the /etc/hosts and /dev/null...

note the back tilts - command executed and the output is used

say if the node name is unixcom
much similiar to searching like

>hostname
unixcom

>grep unixcom /etc/hosts /dev/null

HOST_ALIASES(5) 					   Sun Grid Engine File Formats 					   HOST_ALIASES(5)

NAME
host_aliases - Sun Grid Engine host aliases file format DESCRIPTION
All Sun Grid Engine components use a hostname resolving service provided by the communication library to identify hosts via a unique host- name. The communication library itself references standard UNIX directory services such as DNS, NIS and /etc/hosts to resolve hostnames. In rare cases these standard services cannot be setup cleanly and Sun Grid Engine communication daemons running on different hosts are unable to automatically determine a unique hostname for one or all hosts which can be used on all hosts. In such situations a Sun Grid Engine host aliases file can be used to provide the communication daemons with a private and consistent hostname resolution database. The location for the host aliases file is <sge_root>/<cell>/common/host_aliases. FORMAT
For each host a single line must be provided with a blank, comma or semicolon separated list of hostname aliases. The first alias is defined to be the unique hostname which will be used by all Sun Grid Engine components using the hostname aliasing service of the communi- cation library. SEE ALSO
