@tsmaeder Don't we support this?

[tsmaeder]

According to the code in vsc-cli.ts we do. @agreedSkiing if this is not working for you, could you give steps to reproduce, please?

Message ID: ***@***.***>Should probably have tried it, but was mostly going by that the theia appimage cli didn't show me any help when I passed the -h or --help flag.

If I recall correctly, the AppImage should ask you to install the theia cli command upon first start. I don't think the app image processes cli commands. Command line handling could use a bit of rework, probably.

That is what I got, but yesterday I removed the AppImage with the help of AppImageLauncher from my Arch install since the performance wasn't that great :/. Need to check if that also removed the cli parts.
