Usage: cleanup_i3_after_sway_migration.sh [--apply] [--aggressive]
|
||||
|
||||
One-shot cleanup for removing i3/X11-only packages and dotfiles after a host
|
||||
has already migrated to SwayFX + Noctalia.
|
||||
|
||||
Options:
|
||||
--apply perform the cleanup for real
|
||||
--aggressive also remove extra desktop apps/configs that were mainly useful
|
||||
in the old i3 setup (dunst, rofi, blueman, etc.)
|
||||
-h, --help show this help
|
||||
|
||||
Default mode is dry-run.
