Copy and unzip files from windows to remote linux machine - powershel script - powershell

Question

I have a ./build folder (inside a project on a Windows machine) that I need to compress and send to a remote Linux server where I need to unzip it.
Here's the cmdlet function that I wrote (it doesn't work as intended):
function scpFileFromBuildFolder {
param (
[string]$userAndHost,
[string]$targetDirectory,
)
Compress-Archive -Force -Path "./build/" -Destinationpath "./build/main.zip" -CompressionLevel Optimal
Write-Host -fore Cyan "`r`nCopying archive from ./build/ to ${targetDirectory}"
. scp "./build/main.zip" "${userAndHost}:${targetDirectory}"
Write-Host -fore Cyan "`r`nDecompressing archive on a remote directory:"
. ssh $userAndHost ". cd ${targetDirectory}"
. ssh $userAndHost ". unzip main"
. ssh $userAndHost ". cd build/"
. ssh $userAndHost ". find . -maxdepth 1 -exec mv {} .. \" # move all files to a parent dir
. ssh $userAndHost ". cd .."
. ssh $userAndHost ". rm -rf build build.zip main"
. ssh $userAndHost ". exit"
}
As you can see, I tried to perform multiple commands on a remote server via ssh. All of that works if I do things manually through PowerShell: I compress the file, scp it, and ssh to the server where I unzip the file and do all the other things. But it doesn't work this way through a .ps1 script — it only copies the file but doesn't do anything after the print statement ("Decompressing archive on a remote directory:").
Please, help me finish this function.

You should only run ssh once, with any remote commands getting fed to ssh up through to exit. Otherwise it will just pause and wait for more commands. For example:
ssh $UserAndHost "cd /tmp; hostname; pwd; exit"
You can put them on separate lines like a bash script, BUT be careful of crlf line endings (or strip them):
Write-Host -fore Cyan "`r`nDecompressing archive on a remote directory:"
ssh $userAndHost "cd ${targetDirectory}
unzip main
cd build/
find . -maxdepth 1 -exec mv {} .. \ # move all files to a parent dir
cd ..
rm -rf build build.zip main
exit"
# ERROR if crlf like:
bash: line 1: $'\r': command not found
