#!/usr/bin/perl # This script takes a command-line arg of a source directory # that will be passed to rsync, and generates a set of excludes # that will exclude all mount points from the list. This is # useful if you have "bind" mounts since the --one-file-system # option won't notice the transition to a different spot on # the same disk. For example: # # mnt-excl /dir | rsync --exclude-from=- ... /dir /dest/ # mnt-excl /dir/ | rsync --exclude-from=- ... /dir/ /dest/ # ssh host mnt-excl /dir | rsync --exclude-from=- ... host:/dir /dest/ # # Imagine that /dir/foo is a mount point: the first invocation of # mnt-excl would have output /dir/foo, while the second would have # output /foo (which are the properly anchored excludes). # # NOTE: This script expects /proc/mounts to exist, but could be # easily adapted to read /etc/mtab or similar. # # ADDENDUM: The addition of the --filter option (which has support for # absolute-anchored excludes) can make this script unneeded in some # scenarios. If you don't need delete protection on the receiving side # (or if the destination path is identical to the source path), then you # can exclude some absolute paths from the transfer based on the mount # dirs. For instance: # # awk '{print $2}' /proc/mounts | grep -v '^/$' | \ # rsync -avf 'merge,/- -' /dir host:/dest/ use strict; use warnings; use Cwd 'abs_path'; my $file = '/proc/mounts'; my $dir = shift || '/'; my $trailing_slash = $dir =~ m{./$} ? '/' : ''; $dir = abs_path($dir) . $trailing_slash; $dir =~ s{([^/]*)$}{}; my $trailing = $1; $trailing = '' if $trailing eq '.' || !-d "$dir$trailing"; $trailing .= '/' if $trailing ne ''; open(IN, $file) or die "Unable to open $file: $!\n"; while (<IN>) { $_ = (split)[1]; next unless s{^\Q$dir$trailing\E}{}o && $_ ne ''; print "- /$trailing$_\n"; } close IN;
