Vista - More.com?? Quirk

I've found a real oddity in PowerShell 1.0 RTW on two machines (one
XP, one Windows 2003)

Run this command:

get-childitem function:he* | format-list

Pay attention to the value of Definition.

Notice that there are several references to "more.com" where I think
it ought to be simply "more". At least that's what I see on my
machines.

Can others confirm this?

One for Connect, I suspect, if it's confirmed.

Why did I turn this up? On one machine running the command

help about_reserved_words

produced an error as below.

PS script:\> help about_reserved_words
The term 'more.com' is not recognized as a cmdlet, function, operable
program, or script file. Verify the term and try
again.
At line:94 char:64
+ get-help $Name -Category $Category | more.com <<<<
PS script:\>

Oddly, on the other machine the command produces the desired output.

I have tested on two machines running Windows XP w/ SP2 and Windows 2003 w/
SP1. But i have not been able to confirm for that oddity.

On both systems, running the previous commands resulted in the following
output

[^_^]PS[10]> get-childitem function:he* | format-list
Name : help
CommandType : Function
Definition : get-help $args[0] | out-host -paging

I have a feeling that your profile might dot source a custom "help" function
<... 5 minutes later...>

Oh, i have just started a powershell instance with "-noprofile"
flag(powershell -nologo -noprofile) and when i ran (get-childitem
function:he* | format-list) command again, the definition is a lot longer
than what I pasted above...

Now I can see a lot of places where "more.com" is used.

Even with "-noprofile" i wasn't able to get above errors,
but instead of getting powershell "more" prompt "<SPACE> next page; <CR>
next line; Q quit",
powershell prompted with "-- More --", which more.com should be responsible

lol, never noticed as I had ...

set-alias more more.com

.... in my profile allready ;-)

Hi Andrew,

Yes. There are at least 17 references to more.com:

0:29 > (get-childitem function:he* | % {$_.Definition.Split("`r`n")} |
?{$_ -match "more.com";} | measure-object).Count
17

To confirm your error message, you only have to rename more.com and
watch for the output of "help about_reserved_words":

0:30 > ren "$env:windir\System32\more.com" more.com.bak
0:31 > help about_reserved_words
Die Benennung "more.com" wurde nicht als Cmdlet, Funktion, ausführbares
Programm oder Skriptdatei erkannt. Überprüfen S
ie die Benennung, und versuchen Sie es erneut.
Bei Zeile:94 Zeichen:64
+ get-help $Name -Category $Category | more.com <<<<

That's the error message you already posted - in German as you might
have guessed ;-)

btw: don't forget to rename more.com thereafter ;-)

0:32 > ren "$env:windir\System32\more.com.bak" more.com

hth

Max

btw:

Tested on the following machines:
- Win XP Pro SP2 with PoSh 1.0 RTM
- W2k3 Standard SP1 with PoSh 1.0 RTM

both a German versions

hth

I didn't see it either. This is what I got

PS> Get-ChildItem function:he* | Format-List


Name : help
CommandType : Function
Definition : clear-host
get-help $args[0] -full

I am seeing what you are seeing (references to more.com).

Could this be something to do with the PSCX community extensions (a wild
guess, but it's the only think I can think of).

Hi Thomas,

I haven't had PSCX on any of my machines. So, at least at this end,
that can't be the explanation.

Andrew Watt MVP

Hi Andrew,

Help function uses more.com as the experience using more.com is a little
better than the default more (out-host -p)

For example:

*****************************
PS C:\temp> help -full add-content > temp.txt
PS C:\temp> gc temp.txt

NAME
Add-Content

SYNOPSIS
*****************************

PS C:\temp> (get-help -full add-content | more ) > temp.txt

will not redirect output.

We want to improve out-host in our feature releases.

Thanks, Krishna, for the background information.

As you say it's a "feature" that needs to be improved in a future
release of PowerShell.
