Upgrading MSH, My first Windows PowerShell Commands



My first 3 Windows PowerShell Commands

$host.version
PS G:\MOWSH> $host.version

Major Minor Build Revision
----- ----- ----- --------
1 0 9567 0

# let me run my scripts No Regedit !!

Set-ExecutionPolicy RemoteSigned

Move Profile to Documents and Settings\All Users\Documents\PSConfiguration\Microsoft.PowerShell_profile.ps1


# rename my scripts (otherwise my profile opens with notepad)

ls . *.msh -rec %| {rename-item $_.fullname ($_.name -replace ".msh",".ps1")}

now cleaning up, all the subscript calls in my profile ;-(

and ofcource the CMDlet name changes :

CMDLET RENAME: combine-path -> join-path
CMDLET RENAME: parse-path -> split-path
CMDLET RENAME: match-string -> select-string
CMDLET RENAME: time-expression -> measure-command
CMDLET RENAME: write-object -> write-output
CMDLET RENAME: All *-property cmdlets renamed to *-itemproperty: clear-itemproperty, copy-itemproperty, get-itemproperty, move-itemproperty, new-itemproperty, remove-itemproperty, set-itemproperty
CMDLET RENAME: trace-expression -> trace-command
CMDLET RENAME: invoke-command -> invoke-expression
CMDLET RENAME: Import-SecureString -> ConvertTo-SecureString
CMDLET RENAME: Export-SecureString -> ConvertFrom-SecureSring
CMDLET RENAME: Get-Provider -> Get-PSProvider
CMDLET RENAME: Get-drive -> Get-PSDrive
CMDLET RENAME: New-drive -> New-PSDrive
CMDLET RENAME: Remove-drive -> Remove-PSDrive

even my Custom Typeformatting has to be renamed
MowTypes.PS1XML

hmm, not a fun upgrade becouse of all that renaming, but tomorrow I will show some cool new tricks, and we will forget all those troubles.

b.t.w. a lot of older script on my blog will need a bit of fixing after this,
I will post updated versions of the bigger scripts later on.

I understand this:

ls . *.msh -rec %| {rename-item $_.fullname ($_.name -replace ".msh",".ps1")}


but I was bummed that this didn't work:

ren *.msh *.ps1

Thanks for the Comment,
that was the first think I did look for also, but .

The -newpath parameter does not take Wildcards (the -path does say it does but does not also) , but you can also use a scriptblock like this :

ls . *.msh -rec | rename-item -newname {$_.name -replace ".msh",".ps1"} -WhatIf

as pointed out to by Bruce Payette in the NG, better as the foreach but still no ren *.msh *.ps1 ;-)

another hack wold be Use good old CMD LOL,

cmd /c 'ren *.foo *.bar'
