This change causes
bash
to substitute a null string for variables that are referenced, but unset. This prevents error messages when running bash withset -u
.e.g. "bash: VSCODE_INJECTION: unbound variable"
To test:
set -u
in your~/.bashrc
, to show an error message when unset variables are referenced
