Powershell posh-ssh：如何存储Invoke-SSHCommand的结果？

Question

How can I store the result of Invoke-SSHCommand for use after I close the connection?

I've tried 2 different ways:

#method 1
$result = Invoke-SSHCommand -Index 0 -Command "ls /somepath"

#method 2
Invoke-SSHCommand -Index 0 -Command "ls /somepath" -OutVariable $result

The variable $result is empty after both methods

Answer 1

This worked well for me :

# Create SSH Session
$ssh = New-SSHSession -ComputerName $PC01 -Credential $credential -AcceptKey 1

# Invoke SSH command and capture output as string (you can return the full object if you like, I just needed the string Out)
$ret = $(Invoke-SSHCommand -SSHSession $ssh -Command "racadm getconfig -g cfgUserAdmin -i 2").Output

# return object is a String - if you want it as an array of strings for each row returned
$ret = $ret.split("`n")

Answer 2

This was working for me:

#method 1
$CurrentSession=New-SSHSession -ComputerName x.x.x.x -Credential (Get-Credential) 
$result = Invoke-SSHCommand -SSHSession $CurrentSession -Command "ls /somepath"
$result.Output

Answer 3

Remove the $ from your -OutVariable $result and it should work.

Invoke-SSHCommand -Index 0 -Command "ls /somepath" -OutVariable result

Your $result in the command was being processed, returning null, then trying to output the results of Invoke-SSHCommand to null as far as I can tell
