Filtering and copying with PowerShell
- by Bergius
In my quest to improve my PowerShell skills, here's an example of an ugly solution to a simple problem. Any suggestions how to improve the oneliner are welcome.
Mission: trim a huge icon library down to something a bit more manageable. The original directory structure looks like this:
/Apps and Utilities
/Compile
/32 Bit Alpha png
/Compile 16 n p.png
/+ 10 or more files
/+ 5 more formats with 10 or more files each
/+ 20 or so icon names
/+ 22 more categories
I want to copy the 32 Bit Alpha pngs and flatten the directory structure a bit. Here's my quick and very dirty solution:
$dest = mkdir c:\icons; gci -r | ? { $_.Name -eq '32 Bit Alph
a png' } | % { mkdir ("$dest\" + $_.Parent.Parent.Name + "\" + $_.Parent.Name); $_ } | gci | % { cp $_.
FullName -dest ("$dest\" + $_.Directory.Parent.Parent + "\" + $_.Directory.Parent) }
Not nice, but it solved my problem. Resulting structure:
/Apps and Utilities
/Compile
/Compile 16 n p.png
/etc
/etc
/etc
How would you do it?
