Recursively removing directories and/or files is always quicker this way! This particulary instance I needed to clean out the notes folder from an subversion repository (not necessarily necessary, but this can be applied wherever).
|
1 |
C:\Users\SloshDev> gci -include _notes -Recurse | %{ ri $_.FullName -recurse } |
or you could…
|
1 |
C:\Users\SloshDev> Get-ChildItem -include _notes -Recurse | %{ remove-item $_.FullName -recurse } |
Quick way to get all of the ServerName’s values from the Apache configuration? Especially useful if VirtualHosts have been split into multiple files:
|
1 |
cat *.conf | egrep "ServerName (.*)" | sed "s/ServerName\s\(.*\)/\1/" |

Find String in Files with Given Extension Using PowerShell
Here’s a quick one-liner to re-size photos if you have Imagick installed using PowerShell. It also renames the files with the dimensions specified:
|
1 2 |
PS C:\Users\SloshDev> gci("*.jpg") | %{convert $_.FullName -resize 500x500 $_.Name -replace '\.jpg$','-500x500.jpg'} |
Ultimately ended up with this to rename the file based on the actual dimensions of the file in the end:
|
1 2 |
PS C:\Users\SloshDev> gci("*.jpg") | %{convert $_.FullName -resize 500x500 -set filename:area '%wx%h' ($destination + ($_.Name.Trim("\.jpg") + "-%[filename:area].jpg"))} |
This is great if you want to do this within the file itself, however if you need to specify dimensions, source and destination directories, and specific image file extensions you could use a script like this:
|
1 2 3 4 5 6 7 |
$source = 'C:\User\SloshDev\My Pictures\' $destination = 'C:\User\SloshDev\My Pictures\500's\' $ext = "jpg" $size = "500x500" #Resize Images gci("$source*.$ext") | %{convert $_.FullName -resize $size -set filename:area '%wx%h' ($destination + ($_.Name.Trim("\.$ext") + "-%[filename:area]." + $ext))} |
IIS 6.0 did not save configuration files with “.xml” extension automatically. So I needed to add the .xml to the files. So this is what I did:
|
1 |
PS C:\_old-IIS-site-configurations> Get-ChildItem *.com | Rename-Item -NewName { $_.Name + ".xml"; } |
Nice, quick one-liner to quickly eliminate what would be a pain otherwise.
If you’ve ever wanted a tab delimited list of product attributes and prices to update pricing, here’s one way:
Export product attributes through ‘Utilities > Export Data > Export Attributes to XML File’
|
1 2 |
PS C:\>$a = Get-Content .\provide.xml PS C:\>Set-Content .\provide.xml -value "<products>",$a,"</products>" |
Now bring in file as xml:
|
1 |
PS C:\>$xml = [xml] (Get-Content .\provide.xml) |
Run this command to generate a tab delimited list of Product_Code, Code, & Price
|
1 2 |
PS C:\>$xml.Products.ProductAttributeOption_Add | foreach { $_.product_code + "`t" + $_.Price } > .\provide-list.txt |

Here I needed to make sure that the user input was formatted correctly for a MySQL database. The javascript calendar code was set to automatically input the date into the text field in the correct format, but the user still had the option to type it in manually. This was the Prototype validator I used to verify that the user had entered it correctly as ‘YYYY-MM-DD’:
|
1 2 3 4 5 |
<script type="text/javascript"> Validation.add('required-date-format','Please Enter date as YYYY-MM-DD. Click the calendar icon to select a date.', function(v) { return !Validation.get('IsEmpty').test(v) && /^([0-9]{2,4})-([0-1][0-9])-([0-3][0-9])$/.test(v); }); var warrantyregistrationForm = new VarienForm('warrantyregistrationForm', true); </script> |

The public battle between Adobe and Apple over bringing Flash to the iPhone, and now iPad, platforms has heated up the debate over the life expectancy of Flash as newer technologies, specifically the emerging HTML5 standard, enter the scene.
Adobe Flash helped to fill a void for a cross-platform multimedia experience on the Web. With the glaring exception of the iPhone and upcoming iPad, Flash can be found on virtually every other operating system–desktop and mobile, and for every Web browser….
