Enhanced profile – Display my custom functions
Somehow, I can be compared to a goldfish : my memory is really, really poor… And I do eat fish! But no, I can’t help…
Sometimes I wrote a usefull function that I embed in my profile and some weeks after (ok, even the very next day) I forget about it… So, here’s my solution: list these functions in a MOTD way. Each time I open a PowerShell console, the list is displayed and my memory gets refreshed.
Get-VMsByClusterNode

Get-UptimeDays | Get-Uptime
SafeCopy
A promise is a promise, here’s my second (planned) application around MD5 hash: a function to copy files and check that the MD5 hash of the copied file is equal to the MD5 hash of the source file.
SafeCopy | Check-MD5 | BruteForceMD5
Check-MD5
Here’s a great function to generate the MD5 hash of a specified string.
Let’s have a break
Have a break… No, no panda bears here! Sometimes, we want the user to aknowledge an information before the script continues. We …
PowerShell Menus ($Host.UI.PromptForChoice) – Defined or… Dynamic!
Sometimes, we want to interact with the user who runned a script. The main purpose of this interaction is that the script …
