\/\/Re-Use PowerShell Scriptblocks\/\/<\/p>\n
I commented on a blog post today that showed how to use a hash table with Select-Object to format file sizes say as KB.<\/p>\n
dir $env:temp -rec | select fullname,@{Name="KB";Expression={$_.length\/1kb}}<\/p>\n
Since you most likely will want to use something similar for other directories, don't feel you have to re-invent the wheel. Save the hashtable as a scriptblock. Here are some examples:<\/p>\n
$KB=@{Name="SizeKB";Expression={$_.length\/1kb}}
$MB=@{Name="SizeMB";Expression={$_.length\/1mb}}
$GB=@{Name="SizeGB";Expression={$_.length\/1gb}}<\/p>\n
Now, you can get formatted sizes<\/p>\n
dir ~documents -recurse | select fullname,$mb
dir e:vboxdisks -recurse | select name,$gb | format-table -auto<\/p>\n
Or if you want to format the number, just update the hash table:<\/p>\n
$MB=@{Name="SizeMB";Expression={"{0:F2}"-f ($_.length\/1mb)}}<\/p>\n
If you define these ahead of time, you can reuse them as needed depending on how you want to format the data.<\/p>\n
What other custom scriptblock suggestions do you have?<\/p>\n","protected":false},"excerpt":{"rendered":"
