`ncs-uninstall` - Command to remove NCS installation

## Synopsis

`ncs-uninstall --ncs-version [Version] [--install-dir InstallDir] [--non-interactive]`

`ncs-uninstall --all [--install-dir InstallDir] [--non-interactive]`

## Description

The `ncs-uninstall` command can be used to remove part or all of an NCS "system installation", i.e. one that was done with the `--system-install` option to the NCS installer (see [ncs-installer(1)](/guides/nso-6.6/resources/man/ncs-installer.1.md)).

## Options

`--ncs-version [ Version ]`

> Removes the installation of static files for NCS version \<Version>. I.e. the directory tree rooted at `InstallDir/ncs-Version` will be removed. The \<Version> argument may also be given as the filename or pathname of the installation directory, or, unless `--non-interactive` is given, omitted completely in which case the command will offer selection from the installed versions.

`--all`

> Completely removes the NCS installation. I.e. the whole directory tree rooted at \<InstallDir>, as well as the directories for config files (option `--config-dir` to the installer), run-time state files (option `--run-dir` to the installer), and log files (option `--log-dir` to the installer), and also the init script and user profile scripts.

`[ --install-dir InstallDir ]`

> Specifies the directory for installation of NCS static files, like the `--install-dir` option to the installer. If this option is omitted, `/opt/ncs` will be used for \<InstallDir>.

`[ --non-interactive ]`

> If this option is used, removal will proceed without asking for confirmation.
