Vista - variable display?

is there a way to list out all variables?

i tend to leave my console up for days at a time and toss things in here and
there... can i get a list of what variables i have out there? can it show
the values?


also is there a time out period for those or do they last forever? if they
last, there is obviously a bit of a resource issue that could arise huh?

Thanks
Justin

PowerShell keeps the variables in the Variable: PSProvider. You can view them like:

ls variable:

Variables are live throughout the session unless you remove or clear them.

Also, you can just create all variables beginning with $myvar, for
example, then you can easily do something like 'remove-variable myvar*'
to clear out all the variables you created.

Hi Justin,

I just want to add a few more things to what's already been said.

I have posted a powerful one-liner that can be used to retrieve all
variables, their values, descriptions, types, etc. here:

If you don't follow a standard naming scheme as Marco has recommended, you
could always open a new PowerShell window and retrieve the variables in that
session, retrieve the variables in your old session, and compare the two to
see what has changed.

And one last hint: most (but not all!) of the system variables have
descriptions. I suspect your variables don't have descriptions (most people
don't create variables with descriptions). You could write a script to
retrieve all variables without descriptions whose name is not in the list of
system variables that don't have descriptions (and you could retrieve that
list from a new PowerShell session).
