upstream-seaweedfs/test/samba/run.sh

#!/usr/bin/env bash
#
# Run the SMB (Samba) integration test against a SeaweedFS FUSE mount.
#
# Pipeline:
#   1. start a self-contained "weed mini" (master + volume + filer in one)
#   2. mount the filesystem with "weed mount"
#   3. export a subdirectory of the mount over SMB with smbd
#   4. drive the share with smbclient (test/samba/smb_tests.sh)
#
# Everything runs as the current user on unprivileged ports, so no sudo is
# required. State lives under a temp work dir and is removed on exit.
#
# Requirements: weed in $PATH, fusermount3, and Samba's smbd / smbclient /
# smbpasswd (Debian/Ubuntu: apt-get install samba smbclient).
#
# Usage:
#   test/samba/run.sh
