PERL_ROOT - Need info how it works
|
|
| Rathna N 2005-03-28, 8:55 am |
| Hi,
I've a very basic question for clarification.
1.c:/script1 has below lines
$ENV{PERL_ROOT} ='D:/';
open(fh,'perl script2.pl |');
$x=<fh>;
close fh;
print $x;
2. Script2 has just one line
print "hello";
When I execute the script 1, it doesn't execute or find script2.
It works fine, if I give complete path.
Any idea, why its happening so.. ?
any pointers to some documentation, how PERL_ROOT really works is also welcome.
thanks in advance.
Regards,
Rathna.

perldoc perlrun
PERL_ROOT (specific to the VMS port)
A translation concealed rooted logical name that contains
perl and the logical device for the @INC path on VMS only.
Other logical names that affect perl on VMS include
PERLSHR, PERL_ENV_TABLES, and SYS$TIMEZONE_DIFFERENTIAL but
are optional and discussed further in perlvms and in
README.vms in the Perl source distribution.
So, are you running your programs on the VMS operating system?

| Hi, thanks for the response,
I observed this behavior on Windows, Linux and NetWare.

'D:/' would make little sense on Linux and IIRC on NetWare either? (Unless
you have the directory D: in the current directory, for example
/home/rathna/D:.) The documentation says that it affects the @INC path but
your example doesn't reference the @INC path.
