From 2e210b2387904ada0417ad5a7502e4e40b852e02 Mon Sep 17 00:00:00 2001 From: Eelco Dolstra Date: Wed, 6 Sep 2006 14:23:04 +0000 Subject: [PATCH] * Convenience option `nix-collect-garbage -d' (--delete-old): removes old generations of *all* profiles in /nix/var/nix/profiles, then runs the garbage collector. Quick way to get rid of all old stuff. Of course, one cannot roll back to earlier points in time after this. --- scripts/nix-collect-garbage.in | 44 ++++++++++++++++++++++++++++++++-- 1 file changed, 42 insertions(+), 2 deletions(-) diff --git a/scripts/nix-collect-garbage.in b/scripts/nix-collect-garbage.in index 7ec9f349b..81975d2d3 100644 --- a/scripts/nix-collect-garbage.in +++ b/scripts/nix-collect-garbage.in @@ -1,2 +1,42 @@ -#! @shell@ -e -exec @bindir@/nix-store --gc "$@" +#! @perl@ -w + +use strict; + +my $profilesDir = "@localstatedir@/nix/profiles"; + + +# Process the command line arguments. +my @args = (); +my $removeOld = 0; + +for my $arg (@ARGV) { + if ($arg eq "--delete-old" || $arg eq "-d") { + $removeOld = 1; + } else { + push @args, $arg; + } +} + + +# If `-d' was specified, remove all old generations of all profiles. +# Of course, this makes rollbacks to before this point in time +# impossible. +if ($removeOld) { + + opendir DIR, $profilesDir or die; + + foreach my $name (sort (readdir DIR)) { + $name = $profilesDir .
