使用 rdiff-backup 时遇到问题

Question

我在 rdiff-backup 自动化方面遇到了麻烦。目前有 2 个问题。

脚本本身：

#!/bin/bash
​# This is backup script for rdiff-backup

# Backup command
​rdiff-backup --include-globbing-filelist /home/administrator/backup.list / /mnt/backup/dst

#Checking rdiff-backup command success / error
status=$?
if [ $status != 0 ]; then
        # Append error message in ~/backup.log file
        echo "rdiff-backup exit Code: $status - Command Unsuccessful">>~/varundus.log;
        exit 1;
fi
# Remove incremental backup files older than two weeks
​rdiff-backup --force --remove-older-than 1W /mnt/backup/dst/

第一个问题是，终端在执行时出现错误：

rdiff-backup --force --include-globbing-filelist backup.list / /mnt/backup/dst/

错误：

Found interrupted initial backup. Removing...
Fatal Error: Last selection expression:
Command-line include glob: /var/www
only specifies that files be included.  Because the default is to
include all files, the expression is redundant.  Exiting because this
probably isn't what you meant.

是什么原因造成的？

第二个错误是，如果我运行我的脚本，我会得到：

./inc-backup.sh: line 5: ​rdiff-backup: command not found
./inc-backup.sh: line 9: syntax error near unexpected token `then'
./inc-backup.sh: line 9: `​if [ $status != 0 ]; then'

为什么那个 shell 找不到命令，但是如果我手动输入它，它就可以工作（但第一部分有错误）。有人能解释一下我做错了什么吗？谢谢 :)
