    Hi, 

    How can I make the following works:

    $logParams = '-noclobber -append'
start-transcript -path ".\log.txt" $logParams

    So far I get 

    A positional parameter cannot be found that accepts argument '-noclobber -append'

    error. 

    Thanks

    This will work:

    $logParams=@{
     NoCLobber=$true
     Append=$true
     Path-".\log.txt"
}
start-transcript @logParams

    ¯\_(ツ)_/¯

    thanks. That works. Now, 

    - how to write that $logParams=@ assignment in one line?

    - how to construct it gradually?

    $logParams=@{
         NoCLobber=$true
         Append=$true
    }

    $logParams+= @{Path=".\log.txt"}

    ?

    Thanks

    There is no point to what you are doing.

    $logFile='.\log.txt'
Start-Transcript @{
     NoCLobber=$true
     Append=$true
    Path=$logfile
}
OR ---
Start-Transcript -NoCLobber -Append -Path $logfile
# both are equivalent.

    ¯\_(ツ)_/¯

    That will work, provide that key isn't already present in the hash table (if it is, you'll get an error)  Also  
    $logparms[Path] = '.\log.txt'

$logparms.Path = '.\log.txt'
    will work, and will replace the existing value if there is already a key by that name in the hash table.

    [string](0..33|%{[char][int](46+("686552495351636652556262185355647068516270555358646562655775 0645570").substring(($_*2),2))})-replace " "

    There is no point to what you are doing.

    FYI, I want to warp it with my function 

    function MyLogging ($logFile, $logParams = '-noclobber -append')

    then call start-transcript from within MyLogging.

    Why?

    What does it do that the regular calling methods cannot do?

$logparms.Path = '.\log.txt'

    PS C:\temp> $logParams

Name                           Value
----                           -----
NoCLobber                      True
Append                         True


PS C:\temp> $logParams[Path] = '.\log.txt'
At line:1 char:12
+ $logParams[Path] = '.\log.txt'
+            ~
Array index expression is missing or not valid.
At line:1 char:12
+ $logParams[Path] = '.\log.txt'
+            ~~~~~
Unexpected token 'Path]' in expression or statement.

    The other one works. 

    Thanks
