A reader<\/a> (thanks Jeff<\/a>!) of my previous post<\/a> wrote to mention that there’s an even easier way to insert a space between characters. Use the -replace<\/code> operator thus:<\/p>\n

-replace '([0-9a-f]{2})', '$1 '<\/pre>\n
So simple!\u00a0<\/p>\n
The -replace<\/code> help page<\/a> doesn’t give much details on using regular expressions. Jeff pointed to the Regex.Replace()<\/code> method help page<\/a>, which is where he got the idea from. I tried to search for more info on this and came across this post<\/a> by Don Jones and this Wiki page<\/a> on TechNet.\u00a0<\/p>\n
I had\u00a0wanted to use the -replace<\/code> operator initially\u00a0but was stumped at how to get automatic variables like $1<\/code>, $2<\/code>, $3<\/code>, … for each of the (bracketed) matches it finds. Turns out there’s no need to do that! Each match is\u00a0a $1<\/code>.<\/p>\n
ps.<\/strong>\u00a0From Jeff’s code I also realized I was over-matching in my regular expression. The thumbprints are hex characters so I only need to match [0-9A-F]<\/code> rather than [0-9A-Z]<\/code>. For reference here’s the final code to get certificate thumbprints and\u00a0display with a space:<\/p>\n
Get-ChildItem Cert:\\LocalMachine\\Root | Format-Table @{ Name = \"Thumbprint\"; Expression = { $_.Thumbprint -replace '([0-9A-f]{2})', '$1 ' }}, Subject -AutoSize<\/pre>\n","protected":false},"excerpt":{"rendered":"
