Exporting the `code` command of VS Code

export-vscode-code-command.sh

# Sometimes when opening a remote terminal in VS Code,
# the command `code` is not found. In such case, we
# can simply add the corresponding directory within
# ~/.vscode-server/ to $PATH.
if ! command -v code &> /dev/null
then
  hash_dir=`(cd ~/.vscode-server/bin && ls -trld * && cd ~-) | tail -n1 | awk '{print $NF}'`
