I'm not sure I quote understand. Can you show the code block this is in, some sample input and the output you get?
When you exec a process, it will replace the current shell, so (depending on your OS and version) the redirect you have might be ignored. Can you post the output from uname -a to show your OS and the output from ps to show your shell.
Thanks, in advance,
Robin

bup-ls
bup-ls(1) General Commands Manual bup-ls(1)
NAME
bup-ls - list the contents of a bup repository
SYNOPSIS
bup ls [-s] [-a]
DESCRIPTION
bup ls lists files and directories in your bup repository using the same directory hierarchy as they would have with bup-fuse(1).
The top level directory contains the branch (corresponding to the -n option in bup save), the next level is the date of the backup, and
subsequent levels correspond to files in the backup.
When bup ls is asked to output on a tty, it formats its output in columns so that it can list as much as possible in as few lines as possi-
ble. However, when bup ls is asked to output to something other than a tty (say you pipe the output to another command, or you redirect it
to a file), it will output one file name per line. This makes the listing easier to parse with external tools.
Note that bup ls doesn't show hidden files by default and one needs to use the -a option to show them. Files are hidden when their name
begins with a dot. For example, on the topmost level, the special directories named .commit and .tag are hidden directories.
Once you have identified the file you want using bup ls, you can view its contents using bup join or git show.
OPTIONS
-s, --hash
show hash for each file/directory.
-a, --all
show hidden files.
EXAMPLE
bup ls /myserver/latest/etc/profile
bup ls -a /
SEE ALSO
