Bash raspberry pi，脚本中的apt get update不起作用

当我跑步时：

sudo apt-get update
sudo apt-get upgrade

在命令行中，它可以工作

如果我将同一行放在脚本文件maintain.script中：

echo UPDATING SYSTEM SOFTWARE – UPDATE
sudo apt-get update
echo UPDATING SYSTEM SOFTWARE – UPGRADE
sudo apt-get upgrade

并运行：

sudo ./maintain.sh

我发现错误：

E: Invalid operation update
E: Invalid operation upgrade

我已将脚本标记为可执行文件

在FSQ发表评论后更新

以下是脚本文件：

#!/bin/bash
echo "UPDATING SYSTEM SOFTWARE – UPDATE"
apt-get update
echo "UPDATING SYSTEM SOFTWARE – UPGRADE"
apt-get upgrade
echo "UPDATING SYSTEM SOFTWARE – DISTRIBUTION"
apt-get dist-upgrade
echo "REMOVING APPLICATION ORPHANS"
apt-get autoremove –purge
echo "UPDATING FIRMWARE"
rpi-update

sed -i 's/\r//' maintain.sh

命令如下：

pi@raspberrypi2 ~/projects $ sudo ./maintain.sh

结果如下：

: not foundsh: 1: ./maintain.sh: #!/bin/bash
UPDATING SYSTEM SOFTWARE – UPDATE
E: Invalid operation update
UPDATING SYSTEM SOFTWARE – UPGRADE
E: Invalid operation upgrade
UPDATING SYSTEM SOFTWARE – DISTRIBUTION
E: Invalid operation dist-upgrade
REMOVING APPLICATION ORPHANS

UPDATING FIRMWARE
: not foundsh: 11: ./maintain.sh: rpi-update

将此添加到脚本的开头/bin/bash

这就是它在ubuntu上的工作方式不确定raspbian的情况这是一个文件格式问题。我正在使用Windows记事本通过文件夹共享编辑文件，该记事本使用与Linux不同的\r\n版本

以下是更正我的脚本文件的命令：

#!/bin/bash
echo "UPDATING SYSTEM SOFTWARE – UPDATE"
apt-get update
echo "UPDATING SYSTEM SOFTWARE – UPGRADE"
apt-get upgrade
echo "UPDATING SYSTEM SOFTWARE – DISTRIBUTION"
apt-get dist-upgrade
echo "REMOVING APPLICATION ORPHANS"
apt-get autoremove –purge
echo "UPDATING FIRMWARE"
rpi-update

sed -i 's/\r//' maintain.sh

下面是一个脚本文件，我用来处理文件夹中的所有脚本文件，并确保它们是可执行的：

#!/bin/bash
echo "Correcting script file formats"
for file in *.sh
do
    echo $file
    sed -i 's/\r//' $file
    chmod +x $file
done
