# NAME

bup-drecurse - recursively list files in your filesystem

# SYNOPSIS

bup drecurse [-x] [-q] [--exclude path] [--exclude-from filename] [--exclude-rx pattern] [--exclude-rx-from filename] [--profile] <path>

# DESCRIPTION

`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.
