how to edit a file in powershell remoting session (powershell) - powershell

Question

I am connecting to another computer using powershell remoting, really nice. can do lots, but how do I edit a file?
PS C:\Users\guutlee> Enter-PSSession -ComputerName appprod
[appprod]: PS C:\Users\guutlee\Documents> cd \myapp
[appprod]: PS C:\myapp>
what can I do to open a file editor on a file on the remote machine?
[appprod]: PS C:\myapp> edit app.config
so edit "filename" just seems to hang, from powershell.exe or from powershell_ise.exe
The only thing I can think of is back out of the pssession and "start \webprod\c$\inetpub\myapp\web.config", which would open visual studio.
[appprod]: PS C:\myapp> exit
PS C:\Users\guutlee> start \agobuild\c$\myapp\app.config
PS C:\Users\guutlee> Enter-PSSession -ComputerName appprod
[appprod]: PS C:\Users\guutlee\Documents> cd \myapp
[appprod]: PS C:\myapp> myapp.exe
Of course with this I have to re-find the file, hope that the c$ share is available and accessible, and the reconnect my pssession and re-find my working directory when I want to go on. It doesn't seem very elegant.
I could maybe wrap this is a function, but having a hard time wrapping my head around that..
so how do I conveniently edit a file with a remote pssession?
EDIT
kbrimington's post got me thinking me about the -X option to ssh. probably would be an awesome thing for powershell sessions to be able to forward windowed apps back to the original windowing environment...
but still I'd be happy just to edit the file.
EDIT
tests using vi, emacs, cmd and edit
PS C:\Users\Meredith> Enter-PSSession -ComputerName appprod
[appprod]: PS C:\Users\guutlee\Documents> C:\vim\vim72\vim filename.txt
[appprod]: PS C:\Users\guutlee\Documents> C:\emacs-23.2\bin\emacs.exe -nw filename.txt
emacs.exe : emacs: standard input is not a tty
+ CategoryInfo \: NotSpecified: (emacs: standard input is not a tty:String) [], RemoteException
+ FullyQualifiedErrorId \: NativeCommandError
[appprod]: PS C:\Users\guutlee\Documents> cmd
Microsoft Windows [Version 6.1.7600]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.
C:\Users\guutlee\Documents>
[appprod]: PS C:\Users\guutlee\Documents> edit filename.txt
vi and edit hang (Control-C to get a prompt back)
cmd runs, producing a prompt, but immediately exits back to the powershell prompt
emacs produces the error (standard input is not a tty)
EDIT
Jered suggests pulling the file back locally to edit. I embellished his answer to copying using pssessions rather than UNCs (perhaps this is what he intended)
PS C:\Users\Meredith> Invoke-Command -Session $ps -ScriptBlock {get-content c:/inetpub/myapp/web.config} > web.config
edit web config
PS C:\Users\Meredith> get-content web.config | Invoke-Command -Session $ps -ScriptBlock {set-content c:/inetpub/myapp/web.config}
Potentially we could run the invoke-commands in either direction, local to remote or remote back to local.

Answer 1

If you are using Powershell 5, you can use command called PSEdit. It only works from ISE.
So first, open PowerShell ISE
Then open remote session to the remote computer using Enter-PSSession
Then edit the file using PsEdit 'filename'
The remote file will be opened in a new tab in your (local) ISE window.
Actually I found this answer from the comments section of this SO question , but I think it will be helpful for others if I post it as answer here.

Answer 2

Can you not pull the file locally, edit it and post it? I know this is tedious and not elegant but it seems editors are presently having issue with remote sessions.
E.g.,
Get-Content REMOTE\Filename.txt > LOCAL\Filename.txt
Make your changes locally and then
Set-Content -path REMOTE\Filename.txt -value (get-content LOCAL\Filename.txt)
EDIT
Also if you are only replacing certain instances you can do this pretty easily.
E.g.,
Get-Content REMOTE\Filename.txt | foreach-object { $_ -replace "OLD", "NEW" } | Set-Content REMOTE\Filename.txt

Answer 3

After much digging around, I found something that seems relevant in the powershell help documentation. At the powershell prompt, type:
help about_remote_troubleshooting
At the very end of the help file that is displayed, there is a section entitled 'TROUBLESHOOTING UNRESPONSIVE BEHAVIOUR', which states:
TROUBLESHOOTING UNRESPONSIVE BEHAVIOR
This section discusses remoting problems that prevent a command from
completing and prevent or delay the return of the Windows PowerShell
prompt.
HOW TO INTERRUPT A COMMAND
Some native Windows programs, such as programs with a user interface,
console applications that prompt for input, and console
applications that use the Win32 console API, do not work
correctly in the Windows PowerShell remote host.
When you use these programs, you might see unexpected behavior, such
as no output, partial output, or a remote command that does not
complete. To end an unresponsive program, type CTRL + C. To view any
errors that might have been reported, type "$error" in the
local host and the remote session.
Thus it would seem even non-GUI console applications such as VIM won't work unfortunately. Anyone
care to shed a little light on why this might be the case and/or whether it can be worked
around? I would REALLY love it if I could use vim over powershell remoting.

Answer 4

First, create a temp folder on the local machine (LOCALTEMPFOLDER). Then, use the following function:
function vimrem {param([parameter(position=0,mandatory=$true)][string]$Session, [parameter(position=1,mandatory=$true)][string]$Path)
$TempFile = split-path -path $Path -leaf
copy-item -fromsession $Session -path $Path -destination LOCALTEMPFOLDER\$TempFile
vim $LOCALTEMPFOLDER\$TempFile
copy-item -tosession $Session -path LOCALTEMPFOLDER\$TempFile -destination $Path
remove-item -path LOCALTEMPFOLDER\$TempFile
}
This should work, but you will have leave an interactive session before using this function.

Answer 5

PowerShell_ISE.exe \\REMOTE\...\File.txt
will load and edit the file directly and save it back to the remote computer in one step and, since its command line, easy to build functions using it. Doesn't get around sharing problems, but the easiest way I've found.

Answer 6

Try it out using a console-based editor such as VI or Emacs. As in my comment, I think the problem is that the edit command is bound to a windowed application which, in turn, is not virtualized across a remote session.

Answer 7

I try all the above suggestion and even other microsoft related solution but none works the way you and I want --"full interactive and responsive shell"--. If you really want to have the ssh experience that unix users have from the beggining of time i recomend you install an ssh server. I personally use freesshd, you can find it here http://www.freesshd.com and instructions of how to configure it here http://www.windowsnetworking.com/articles_tutorials/install-SSH-Server-Windows-Server-2008.html. After you make all that it says in the instructions you only need to use any ssh client app to connect to your computer and use powershell full interactive. Vim, edit, emacs or whatever you use to edit a file is going to work without any problem.
i encourage you to not waste your time with psremoting, telnet, winrs, psexec, trying to achieve what a real interactive shell provide (i already lost it, T_T). Try that ssh server an see for your self.

Answer 8

Inspired by the answer provided by #chenz, this can also be done using Visual Studio Code when inside the Powershell Integrated Shell. I tried this with Powershell 7 over SSH remoting, but should also work with WinRM remoting as well.
Enter-Session ...
[RemoteSystem] PS> psedit service.log
The filename will follow this pattern:
C:\users\dev\appdata\local\temp\2\pses-15960\remotefiles\1702137071\winboxname\service.log

Answer 9

I got nano to work easily over SSH to PowerShell. It's available in Chocolatey so you can just do...
choco install nano -y
Then you can just do...
nano filename

Answer 10

I've been looking into this quite thoroughly given the limitations of PSRemoting and the possible work arounds or solutions.
Console editors do not work as they are native (exe) commands and are character based. (I'm wondering if cmd over ssh works with these) It needs to be a cmdlet to properly interact with the console host over a psremote session.
A PSRemote session is line based. You edit the line locally push enter and then it is sent to the remote end, the command is executed and the result returned. So it does support line interactivity but not character interactivity.
Given all these limitations, GNU's ed appears to be a perfect fit. I'm surprised that no one has looked at implementing it as a cmdlet.
I decided to investigate this further, I checked that the powershell cmdlet read-host works and then the C# equivalent PSHostUserInterface.ReadLine() work over a PSRemote session and they do, which is all that is needed to make a working line editor.
So here's what I've done so far. I could probably use some help on the more exotic regex code.
https://github.com/silicontrip/ps-ed
I've used this to edit files via a psremote session. (I wouldn't go editing large source files with it, but for the odd small config file or ps1 script it is perfect.)
Make sure you are familiar with GNU ED before using this cmdlet. It'd be like trying to use VI for the very first time, otherwise.
