PowerShell : How Can I Rename Files Using File Names I've Written to a Text File?



and an other Hey Scripting Guy Item translation to PowerShell,

How Can I Rename Files Using File Names I've Written to a Text File?

import-csv names.csv %| {ren $_.old $_.new}

as this line (as remarked by Scott Hansellman), see Upgrading MSH, My first Windows PowerShell Commands

is a bit awkward opposed to ren *.msh *.ps1 in the CMD shell.

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

you can see, by this example, if you compare it to the VBscript version is not that bad ;-)

Here the commandline code of the sample I made for this :

# make testdir

MowPS>md ren


Directory: Microsoft.PowerShell.Core\FileSystem::C:

Mode LastWriteTime Length Name
---- ------------- ------ ----
d---- 2006-05-11 5:06 PM ren

# create test files

MowPS>cd ren
MowPS>ls
MowPS>sc 001.jpg 'bla'
MowPS>sc 002.jpg 'bla'

# make List

MowPS>copycon
Old,New
001.jpg,foo.jpg
002.jpg,bar.jpg
^Z

cmdlet out-file at command pipeline position 1
Supply values for the following parameters:
FilePath: Names.csv

# CopyCon is a custom Function I like

MowPS>gc function:copycon
if ($args[0] -eq $null) {[system.console]::in.readtoend() out-file}
Else {[system.console]::in.readtoend() out-file $args[0]}

# the "script" itself

MowPS>import-csv names.csv %| {ren $_.old $_.new}

# Checking

MowPS>ls


Directory: Microsoft.PowerShell.Core\FileSystem::C:\ren


Mode LastWriteTime Length Name
---- ------------- ------ ----
-a--- 2006-05-11 5:07 PM 5 bar.jpg
-a--- 2006-05-11 5:06 PM 5 foo.jpg
-a--- 2006-05-11 5:10 PM 88 Names.csv


Enjoy,

Greetings /\/\o\/\/

Marc,

I think you have omitted to split your first two commands into pipeline steps. The | character appears to have been omitted in each line.

Andrew,

thanks for the comment.

I fixed them,

that [censored] blogger interface does eat my pipelines,

if ($args[0] -eq $null) {[system.console]::in.readtoend() out-file}
