The following is a "safe" use of a tmp file - the && only on success will continue with the following command, and the cp leaves the inode/owner/group/permissions/linkage intact.
Or use perl - like sed it will alter inode and linkage.

PERLDGUX(1) Perl Programmers Reference Guide PERLDGUX(1)NAME
perldgux - Perl under DG/UX.
SYNOPSIS
One can read this document in the following formats:
man perldgux
view perl perldgux
explorer perldgux.html
info perldgux
to list some (not all may be available simultaneously), or it may be read as is: as README.dgux.
DESCRIPTION
Perl 5.7/8.x for DG/UX ix86 R4.20MU0x
BUILDING PERL ON DG /UX
Non-threaded Perl on DG/UX
Just run ./Configure script from the top directory. Then give "make" to compile.
Threaded Perl on DG/UX
If you are using as compiler GCC-2.95.x rev(DG/UX) an easy solution for configuring perl in your DG/UX machine is to run the command:
./Configure -Dusethreads -Duseithreads -Dusedevel -des
This will automatically accept all the defaults and in particular /usr/local/ as installation directory. Note that GCC-2.95.x rev(DG/UX)
knows the switch -pthread which allows it to link correctly DG/UX's -lthread library.
If you want to change the installation directory or have a standard DG/UX with C compiler GCC-2.7.2.x then you have no choice than to do an
interactive build by issuing the command:
./Configure -Dusethreads -Duseithreads
In particular with GCC-2.7.2.x accept all the defaults and *watch* out for the message:
Any additional ld flags (NOT including libraries)? [ -pthread]
Instead of -pthread put here -lthread. CGCC-2.7.2.x that comes with the DG/UX OS does NOT know the -pthread switch. So your build will fail
if you choose the defaults. After configuration is done correctly give "make" to compile.
Testing Perl on DG/UX
Issuing a "make test" will run all the tests. If the test lib/ftmp-security gives you as a result something like
lib/ftmp-security....File::Temp::_gettemp:
Parent directory (/tmp/) is not safe (sticky bit not set
when world writable?) at lib/ftmp-security.t line 100
don't panic and just set the sticky bit in your /tmp directory by doing the following as root:
cd / chmod +t /tmp (=set the sticky bit to /tmp).
Then rerun the tests. This time all must be OK.
Installing the built perl on DG/UX
Run the command "make install"
