perldoc error

I have setup perl in environment variable PATH as C:\perl\bin;

When I execute "C:\perl>perldoc perldoc", I get following error message

"C:\Perl>perldoc perldoc
Can't spawn "cmd.exe": No such file or directory at C:/Perl/lib/Pod/Perldoc.pm line 1515.
Can't spawn "cmd.exe": No such file or directory at C:/Perl/lib/Pod/Perldoc.pm line 1515.
Can't spawn "cmd.exe": No such file or directory at C:/Perl/lib/Pod/Perldoc.pm line 1515."

cmd.exe is set in the "ComSpec" environment variable as "C:\WINDOWS\system32\cmd.exe"

Why do I get this error ? How can I get correct output ?

Manish do not see in c:/perl try to see in some other directory for ex c:/perl/bin

Manish do not see in c:/perl try to see in some other directory for ex c:/perl/bin

As long as path for perl is set in environment variable PATH, I shd be able to execute these commands from any directory.
Question is about cmd.exe in perldoc. Why is that not found by the perl interpreter ? As this cmd.exe is set in ComSpec environment variable. Is it supposed to be set some other way ?
Pls explain

bittu

your thinking is correct. Tell me was you able to see perldoc using c:/perl/bin ?
If true.

Please try echo %PATH%

Do it show same path which you mentioned?

bittu

Just try to put in your path C:\perl\bin\;

I added "\" in your path "C:\perl\bin"

bittu

If it user defined variables

use PATH value equal to

".;C:\perl\bin;"

Hope it will help.

What are you talking about? "cmd.exe" is windows Command Shell. Pre-Vista Path is C:\WINDOWS\system32

Just try to put in your path C:\perl\bin\;

I am not sure adding backslash in the path will solve the problem as this problem is related to cmd.exe.

Here is the output for path
"C:\perlfiles>path
PATH=C:\Perl\bin;C:\Program Files\java\jdk1.6.0_11\jre\bin;C:\Program Files\DivX\DivX Player\DivX Player.exe;

Here is the output for echo %ComSpec%
C:\perlfiles>echo %comspec%
C:\WINDOWS\system32\cmd.exe

Its clear that both the path are in place, so why am I getting this error ? Is path for cmd.exe supposed to be in another variable ? Pls explain.

I have setup perl in environment variable PATH as C:\perl\bin;

When I execute "C:\perl>perldoc perldoc", I get following error message

"C:\Perl>perldoc perldoc

Did you ever think to try looking at the line of the file that is referenced in the error message? In my copy of perldoc.pm the line is:

...
         last if system("$pager \"$output\"") == 0;
...

I wonder if the problem is spawning cmd.exe - or spawning cmd.exe to run whatever

$pager

is set to...
Try inserting a line just above the current line 1515 (but within the else statement) like:

...
         warn("PAGER: '$pager'\n");
         last if system("$pager \"$output\"") == 0;
...

and see if that helps shed some light on what is actually failing.

I was suggested to set path as follows

"set path=%windir%\system32
set path=%path%;%windir%
set path=%path%;%windir%\System32\Wbem
set path=%path%;C:\Perl\bin"

when I set path as above, the command "perldoc perldoc" is working fine without any error.

cmd.exe is set in comspec variable which has path C:\WINDOWS\system32\cmd.exe. Does it mean that path for cmd.exe has to be set in "PATH" ?
If the path is set in some other environment variable, will the interpreter not look at those variables for ckecking path ?

why is the path reqiured to be added for Wbem also ?

How do you know what paths are to be set in "PATH" ?(I wb never have thought of setting Wbem in path)

Pls explain

Did you try as Adam's reply?

You can't set the PATH environment variable in another variable. Unless you are setting some other variable like VAR, and then set path to var, like:
SET VAR = c:\windows;c:\windows\system32
SET PATH = %VAR%
It is an environment variable itself, and the cmd.exe or command.exe should be included in any default installation of Windows, unless you manually remove it and then you'll get a bunch of errors. You don't really need to separate all the lines for the path env variable, and can put it in one line.
