nix-sweep

nix-sweep aims to provide a nice interface for cleaning up old Nix profile generations and left-over garbage collection roots.

Size Calculations

Calculating the size of the Nix paths may take a few moments, especially on older hardware. If you want to avoid that overhead you can use --no-size to skip size calculations.

Presets

nix-sweep allows you to create presets for clean out criteria, that can then be used with nix-sweep cleanout.

Preset configs are stored as TOML files. If a preset is present in multiple of those files, then the ones further down in the list override ones further up. The following locations are checked for preset files:

/etc/nix-sweep/presets.toml
$XDG_CONFIG_HOME/nix-sweep/presets.toml/~/.config/nix-sweep/presets.toml
configuration files passed via -C/--config

Example:

[housekeeping]
keep-min = 10
remove-older = 14d
interactive = true
gc = false

Presets can be used with the -p (--preset) flag:

nix-sweep -p housekeeping system
nix-sweep -p only-remove-really-old system
nix-sweep -p nuke-everything system
