bup-drecurse1

Usage

Overview

bup drecurse traverses files in the filesystem in a way similar to find(1). In most cases, you should use find(1) instead.

This program is useful mainly for testing the file traversal algorithm used in bup-index(1).

Note that filenames are returned in reverse alphabetical order, as in bup-index(1). This is important because you can’t generate the hash of a parent directory until you have generated the hashes of all its children. When listing files in reverse order, the parent directory will come after its children, making this easy.

Options

-x, --xdev, --one-file-system

don’t cross filesystem boundaries – though as with tar and rsync, the mount points themselves will still be reported.

-q, --quiet

don’t print filenames as they are encountered. Useful when testing performance of the traversal algorithms.

--exclude=path

exclude path from the backup (may be repeated).

--exclude-from=filename

read –exclude paths from filename, one path per-line (may be repeated). Ignore completely empty lines.

--exclude-rx=pattern

exclude any path matching pattern. See bup-index(1) for details, but note that unlike index, drecurse will produce relative paths if the drecurse target is a relative path. (may be repeated).

--exclude-rx-from=filename

read –exclude-rx patterns from filename, one pattern per-line (may be repeated). Ignore completely empty lines.

--profile

print profiling information upon completion. Useful when testing performance of the traversal algorithms.
