BASH_SOURCE[0] is unbound when bash reads from a pipe; set -u turns this into a fatal error that no amount of :- or set +u reliably fixes across bash versions. $0 is always set: 'bash' when piped (dirname gives '.' where no setup.sh exists), and the correct path when run directly.

#
|
|
# THREE ways to use this:
|
|
#
|
|
# 1. Public repo — paste on any new box (internet required):
|
|
# curl -fsSL https://raw.githubusercontent.com/outis1one/ubuntu-post-install/main/bootstrap.sh | sudo bash
|
|
#
|
|
# 2. Private repo — copy just this file, supply a fine-grained read-only PAT:
|
|
# sudo bash bootstrap.sh --pat ghp_xxxxxxxxxxxxxxxxxxxx
|
|
#
|
|
# 3. USB / offline — copy the WHOLE REPO to a thumb drive, run from there
|
|
# (no auth, no internet needed for the scripts themselves):
|
|
# sudo bash /media/user/DRIVE/ubuntu-post-install/bootstrap.sh
|
|
#
|
|
# Option 3 is the recommended approach for private repos: clone once on a
|
|
# connected machine, put the directory on a USB drive, done.
|
|
set -euo pipefail
|
|
|
|
# Self-elevate: if double-clicked or run without sudo, ask for password.
