Special characters in powershell via QEMU agent

[Furthick]

Hello,
I'm on a symfony project with a php api for proxmox ( https://github.com/CpuID/pve2-api-php-client )
Using QEMU agents, I'm trying to post command in powershell, for example :
powershell.exe Get-DhcpServerv4Scope | Select-Object -Property StartRange,EndRange
But the comma between StartRange and EndRange does not appear and can't be escaped.



Thanks for your help.

hi,

Using QEMU agents, I'm trying to post command in powershell, for example :
powershell.exe Get-DhcpServerv4Scope | Select-Object -Property StartRange,EndRange
But the comma between StartRange and EndRange does not appear and can't be escaped.

could you show us your code?

for me here it works if i try with our qm tool.

for example:

qm guest exec 2000 -- powershell -c 'Get-ChildItem "Env:" | Select-Object -Property Key,Value'

"powershell.exe Get-DhcpServerv4Scope | Select-Object -Property StartRange,EndRange" is in $command

API endpoints seem correct from a glance, so it's most likely because of the specific command

"powershell.exe Get-DhcpServerv4Scope | Select-Object -Property StartRange,EndRange" is in $command

could you try with the -c flag for powershell and the rest of your command quoted? (see my example above)

so your command could be powershell -c 'Get-DhcpServerv4Scope | Select-Object -Property StartRange,EndRange'
