Try using the %ENV hash.
system("expand perfc009.DA_ $ENV{WINDIR}\\system32\\perfc009.DAT") && die
"no $!";

Hi everyone,
I am pretty new to perl so I assume you guys and girls will starting getting
to know me really well.
I have a one line snippet of code that I am trying to run. The system is
win2k sp3. I am trying to run the expand command and pass to it some
arguments that contain system variables.
The code:
#Ok we have renamed the files now we need to run the expand command:
system("expand perfc009.DA_ %windir%\\system32\\perfc009.DAT") && die "no
$!";
and when I run I get it:
C:\Perf>perl -w maintest.pl.txt
Microsoft (R) File Expansion Utility Version 5.00.2134.1
Copyright (C) Microsoft Corp 1990-1999. All rights reserved.
Expanding perfc009.da_ to %windir%\system32\perfc009.dat.
Can't open output file: %windir%\system32\perfc009.dat.
no at maintest.pl.txt line 5.
My first question is; did I do the right thing by putting a \ before the \
in the path?
My second question is whether or not the % sign is messing things up?
Finally I am wondering how best to solve this? DO you think hard coding the
actual path (instead of using %windir% would help?
Thx again!
Leon
