linux - tar 备份错误

Question

我关注了这个问题: How to backup filesystem with tar using a bash script?

但是当我运行脚本时它给出了以下错误:

: not found/backup.sh: 2: /etc/init.d/backup.sh: 
: not found/backup.sh: 5: /etc/init.d/backup.sh: 
: not found/backup.sh: 7: /etc/init.d/backup.sh: 
: not found/backup.sh: 10: /etc/init.d/backup.sh: 
: not found/backup.sh: 12: /etc/init.d/backup.sh: 
/etc/init.d/backup.sh: 13: /etc/init.d/backup.sh: Syntax error: "(" unexpected

这是我的脚本:

#!/bin/bash

#TODAY=$(date +%F)
#HOST=$(hostname)

mybackupname="backup-fullsys-$(date +%Y-%m-%d).tar.gz"

# Record start time by epoch second
start=$(date '+%s')

# List of excludes in a bash array, for easier reading.

excludes=(--exclude=/FILES/Media/Programs/Mint/Backup/$mybackupname)
excludes+=(--exclude=/proc)
excludes+=(--exclude=/lost+found)
excludes+=(--exclude=/sys)
excludes+=(--exclude=/mnt)
excludes+=(--exclude=/MEDIA)
excludes+=(--exclude=/BACKUP)
excludes+=(--exclude=/FILES)

if ! tar -czf "$mybackupname" "${excludes[@]}" /; then
  status="tar failed"
elif ! mv "$mybackupname" FILES/Media/Programs/Mint/Backup/ ; then
  status="mv failed"
else
  status="success: size=$(stat -c%s backups/filesystem/$mybackupname) duration=$((`date '+%s'` - $start))"


# Log to system log; handle this using syslog(8).
logger -t backup "$status"

有人看到我哪里出错了吗？

正如“那个人”评论的那样，这里的解决方案是在 bash 文件上运行 dos2unix convert 命令:

sudo dos2unix /etc/init.d/backup.sh

并使用 bash 命令而不是 sh 命令运行它:

sudo bash /etc/init.d/backup.sh
