Suppose I have the following
[uri]$URL = "https://www.example.com/folder/folder2"
I would like to get this part along with the first local path, i.e. https://www.example.com/folder
In other words, I dont want folder2 etc... because i plan to append this portion to an api path, so eventually i'd have something like $URL + "/api/v2.0/" or https://www.example.com/folder/api/v2.0/
I figured it out using -split
($URL -split "folder2")[0]
this gives https://www.example.com/folder/

If you want to write to a file, append this at the end: -o file.txt
I am trying to batch rename multiple files and so far I am pretty close to what I am trying to achieve. I have some files called "website.txt", "website1.txt", "website2.txt", "website3.txt" and I am trying to rename only the files that have a number associated with them (so excluding "website.txt"). My first attempt is as follows (I'm using -n for testing):
rename -n 's/website/website_edit/' *txt
Result:
rename(website1.txt, website_edit1.txt)
rename(website2.txt, website_edit2.txt)
rename(website3.txt, website_edit3.txt)
rename(website.txt, website_edit.txt)
As you can see this almost works but it is renaming the "website.txt" file as well which I don't want. So to try and remove it I did this:
rename -n 's/website\w/website_edit/' *txt
Result:
rename(website1.txt, website_edit.txt)
rename(website2.txt, website_edit.txt)
rename(website3.txt, website_edit.txt)
This time it did remove "website.txt" from the list but it also removed the the numbers from the end on the new names. I have also tried messing around with some regular expressions as well but to no avail.
Try this :
rename -n 's/website(\d+)/website_edit$1/' *txt

Let me start with I am very new to powershell and programming for that matter. I have a powershell script that takes some arguments and that outputs a value.
The result of the script is going to be something like 9/10 where 9 would be the number active out of the total amount of nodes. I want to assign the output to a variable so I can then call another script based on the value.
This is what I have tried, but it does not work:
$active = (./MyScript.ps1 lb uid **** site)
I have also tried the following which seems to assign the variable an empty string
$active = (./MyScript.ps1 lb uid **** site | out-string)
In both cases they run and give me the value immediately instead of assigning it to the variable. When I call the variable, I get no data.
I would embrace PowerShell's object-oriented nature and rather than output a string like "9/10", create an object with properties like NumActiveNodes and TotalNodes e.g. in your script output like so:
new-object psobject -Property #{NumActiveNodes = 9; TotalNodes = 10}
Of course, substitute in the dynamic values for num active and total nodes. Note that uncaptured objects will automatically appear on your script's output. Then, if this is your scripts only output, you can do this:
$obj = .\MyScript.ps1
$obj.NumActiveNodes
9
$obj.TotalNodes
10
It will make it nicer for those consuming the output of your script. In fact the output is somewhat self-documenting e.g.:
C:\PS> .\MyScript.ps1
NumActiveNodes TotalNodes
-------------- ----------
9 10
P.S. When did StackOverflow start sucking so badly at formatting PowerShell script?
If you don't want to change the script ( and assuming only that $avail_count/$total_count line is written by the script), you can do:
$var= powershell .\MyScript.ps1
Or just drop the write-host and have just $avail_count/$total_count
and then do:
$var = .\MyScript.ps1
you could just do a $global:foobar in your script and it will persist after the script is closed
I know, the question is a bit older, but it might help someone to find the right answer.
I had the similar problem with executing PS script with another PS script and saving the output into variable, here are 2 VERY good answers:

I have a power-shell script with which I am trying to back up a constantly changing number of SQL databases. Fortunately all of these databases are listed in a registry key. I am leveraging this in a for-each loop. The issue that I am having is that after grabbing the registry value that I want, when I try to pass it into my function to back up the databases there seems to be information in the variable that I can get rid of. If I output the contents of the variable to the screen by just calling the variable ($variable) is shows just fine. But if I write-host the variable to the screen the extra "content" that shows up when calling the function also shows up.
Here is the part of the script that generates the contents of the variable.
foreach ($childitem in get-childitem "HKLM:\SOFTWARE\Wow6432Node\Lanovation\Prism Deploy\Server Channels")
{$DBName = get-itemproperty Registry::$childitem | select "Channel Database Name"
write-host $DBname}
Here is what write-host displays :
#{Channel Database Name=Prism_Deploy_Sample_268CBD61_AC9E_4853_83DE_E161C72458DE}
but what I need is only this part :
Prism_Deploy_Sample_268CBD61_AC9E_4853_83DE_E161C72458DE
I have tried looking online at how to do this, and what I've found mentions things similar to $variable.split and then specifying my delimiters. But when I try this I get an error saying "Method invocation failed because [System.Management.Automation.PSCustomObject] doesn't contain a method named 'split'."
I'm at a loss as to where to go from where I'm at currently.
select-object will return an object that has the named properties that you "select". To get just value of that property, just access it by name:
write-host $DBname."Channel Database Name"
Sounds like it's returning a hash table row object.
Try
write-host $DBName.value
or, failing that, do a
$DBName | Get-member
When in doubt, get-member gives you a nice idea of what you are dealing with.
You should be able to write
foreach ($childitem in get-childitem "HKLM:\SOFTWARE\Wow6432Node\Lanovation\Prism Deploy\Server Channels")
{$DBName = get-itemproperty Registry::$childitem | select "Channel Database Name"
write-host $DBname.Name}
to get what you are looking for
I cannot seem to get the following to work
directory <- "./"
files.15x16 <- c("15x16-70d.out", "15x16-71d.out")
data.15x16<-rbind( lapply( as.array(paste(directory, files.15x16, sep="")), FUN=read.csv, sep=" ", header=F) )
What it should be doing is pretty straightforward - I have a directory name, some file names, and actual files of data. I paste the directory and file names together, read the data from the files in, and then rbind them all together into a single chunk of data.
Except the result of the lapply has the data in [[]] - i.e., accessing it occurs via a[[1]], a[[2]], etc which rbind doesn't seem to accept.
Suggestions?
Use do.call:
data.15x16 <- do.call(rbind, lapply(paste(directory, files.15x16, sep=""),
FUN=read.csv, sep=" ", header=F))
You also don't need the as.array - it does not really do anything here.
