A shell script that replace portable¹ VSCode installations from a vscode tar.gz archive. The script doesn't check the version information of the current installation and that from the provided archive, so it can be used to upgrade/downgrade current installations.

The script makes some assumptions:

1- VSCode installations are under the same root directory, pointed at by the environment variable VSCODE_HOME.

2- if VSCODE_HOME is not defined, it's assumed that the portable installations are under directory ~/VSCode/.

Default VSCODE_HOME value can be changed by changing the variable VSCODE_HOME_DEFAULT in the script

3- Each VSCode installation is in a separate direcory, and the directory contains VSCode in its name, eg: VSCode python, VSCode_JS, VSCode-data-science are all valid names and recognizable by the script as VSCode installation.

• Installation name doesn't have to start with VSCode, it can be anywhere in the installation name
• The script uses the variable VSCODE_INSTALLATION_NAME_SLUG to look for VSCode installation directories. It's default value is VSCode, you can change it in the script to whatever suits you.
• The script uses looks for installations in VSCODE_HOME using the command: ls "$VSCODE_HOME" | grep "$GREP_OPTIONS" "$VSCODE_INSTALLATION_NAME_SLUG". It's possible to pass options to grep for a customized lookup, eg: -E, -i, etc.

4- The script assumes the following nested directory structure:

$VSCODE_HOME/
    |-- VSCode {installation_name}/
    |---- code.png
    |---- {VSCODE_INSTALL_NAME}/
    |------ data/
    |
    |-- VSCode {installation_name}/
    |---- code.png
    |---- {VSCODE_INSTALL_NAME}/
    |------ data/
    |-- .
    |-- .
    |-- .
    |-- .

• VSCODE_INSTALL_NAME is the name of the directory that contains VSCode installation files and folders. Its name differs depending on the installation, eg: for linux-x64 it's named VSCode-linux-x64. Default value is VSCode-linux-x64.
• Change the variable VSCODE_INSTALL_NAME to the value that suits your installation. It must match the directory name inside vscode archive code-version.tar.gz.
• code.png is a custom icon for that installation. If found, it will be copied to replace default VSCode icon (currently fund in $VSCODE_DIR/resources/app/resources/linux)
• Each portable installation contains a data directory (installation's portable data, eg: extensions, settings, etc). The data directory is moved into the installation's parent director (VSCcode {installation_name}) before updating the installation, then moved back into the installation directory after the update.
• During update, the old VSCODE_INSTALLATION_NAME directory is deleted, then replaced with the new director from the deflated VSCode archive.

./vscode_update.sh path/to/code-stable-version_number.tar.gz

./vscode_update.sh -h

./vscode_update.sh path/to/code-stable-version_number.tar.gz
Unpacks given vscode.tar.gz and copies it into VSCode installations under VSCODE_HOME
Uses VSCODE_HOME enviroment variable to look for VSCode installations
Assumes the following directory structure:
VSCODE_HOME/
    |
    |-- Install/
    |-- VSCodeXXX
          |-- VSCode-linux-x64
                |-- data
    |-- VSCODEYYY
          |--VSCode-linux-x64
                |-- data
    .
    .
    .

Each VSCode installation ahs a parent directory, name VSCode[suffix].
The parent directory contains a VSCode-linux-x64 direcotry, that contains VSCode files.
In VSCode-linux-x64, a 'data' directory (where 'user-data', 'extensions' and 'tmp') that is moved into the VSCode installation parent directory (VSCode[suffix]), then moved back.
