Maybe I am missing something, but the simplest fix may be just to set an
environment variable named COMPUTERNAME during login on the Unix/Linux system
and it will be available to env.
Sometimes things get more complicated than is necessary...

There
really
isn't
a
standard
environment
variable
name
for
storing
the
system
name
on
the
various
flavors
of
Unix.
This
is
usually
set
when
users
log
in.
Some
shells
do
set
the
environment
variable
HOSTNAME,
but
not
all.
Even
on
Windows,
the
environment
variable
COMPUTERNAME
cannot
be
trusted
because
it
can
changed
by
the
user.
On
Linux,
the
environment
variable
HOSTNAME
is
set
by
the
default
shell
(BASH),
but
not
by
other
shells
like
Bourne,
Csh,
or
Kornshell.
You
could
simply
make
it
a
policy
that
HOSTNAME
should
be
set
on
Unix
logins
in
order
for
your
build
to
work.
This
will
find
the
hostname
whether
it
is
set
in
COMPUTERNAME
(as
on
Windows)
or
HOSTNAME
(as
normally
done
on
Linux/Unix):
<target
name="getname">
<property
environment="env"/>
<condition
property="hostname"
value="${env.HOSTNAME}">
<isset
property="env.HOSTNAME"/>
</condition>
<condition
property="hostname"
value="${env.COMPUTERNAME}">
<isset
property="env.COMPUTERNAME"/>
</condition>
<fail
unless="hostname"
message="You
must
set
the
environment
variable
HOSTNAME
or
COMPUTERNAME
to
use
this
build
script"/>
<echo
message="The
computer's
name
is
"${hostname}"/>
</target>

Ant

But
in

it
prints
the

like
"${env.COMPUTERNAME}".
