编辑脚本以发送电子邮件?

编辑脚本以发送电子邮件?

我基本上试图将我在网上找到的两个脚本放在一起。第一个部分分为两部分,检查目录是否存在,如果不存在则创建目录,如果输入了错误的登录密码,则继续通过网络摄像头拍照。据我所知,这部分工作正常。

#!/bin/bash

## Variables
dir=/tmp/gotcha
got=/tmp/gotcha/gotcha.jpg
[email protected]
[email protected]
SMTPSERVER=smtp.googlemail.com:587
[email protected]
SMTPPASS=xxxxx
SUBJECT="Someone tried to access your computer while you were away."

if test [ -d  "$dir" ]
then 
    echo "Found directory /tmp/gotcha/" ]
else 
    mkdir /tmp/gotcha/
fi

ts=`date +%s`
ffmpeg -f video4linux2 -s vga -i /dev/video0 -vframes 1 $got
exit 0  ## NOTE - must exit with status 0

第二个是应该通过电子邮件将拍摄的照片发送给我,然后从存储目录中删除照片,但据我所知,即使我可以通过命令行和 GUI 找到有问题的文件,它也找不到照片。

## sendEmail script, found in /home/josh/scripts/emailscript
if test -f [ "$got" ]
then
        sendemail -f $SMTPFROM -t $SMTPTO -u $SUBJECT -a $got -s $SMTPSERVER -$
fi

## Remove gotcha.jpg
if test -f [ "$got" ]
then
       rm $got

当我在终端中运行脚本时,输出如下:

/usr/local/bin/gotcha: line 13: test: too many arguments

就像我说的,我是 bash 脚本新手,所以我可能忽略了一些愚蠢的事情,但是任何帮助都是值得赞赏的!

答案1

1) 使用[ -d ...]或者test -d ...但是不是 test -d [ ... ](同样适用于-f

2)test -f [ $file ]

将要

  • 查找名为的文件[
  • 抱怨额外的争论

3)在

if test [ -d  "$dir" ]
then 
    echo "Found directory /tmp/gotcha/" ]
else 
    mkdir /tmp/gotcha/
fi

你可以使用dirvar

if test  -d  "$dir" 
then 
    echo "Found directory $dir" ]
else 
    mkdir "$dir"
fi

答案2

我设法找出我的(重大)错误。我尝试清理很多内容,在此过程中我注意到我使用的 sendEmail 脚本缺少一个选项:

-o tls=yes

最后,脚本完全可以工作,并且看起来更加整洁:

#!/bin/bash

##########
## variable key
file=/tmp/gotcha/pic.jpg
dir=/tmp/gotcha
[email protected]
[email protected]
SMTPSERVER=smtp.googlemail.com:587
[email protected]
SMTPPASS=xxxxx
SUBJECT="Someone tried to access your computer while you were away."
MESSAGE="Someone tried to access your computer while you were away. Here's a photo!"

##########
## create directory if it doesn't exist
if test -d "$dir"
then
        echo "Found directory...";
else
        echo "Directory not found..."
        sleep 1.5
        echo "Creating directory $dir..."
        mkdir -p $dir
        sleep 1.5
        echo "Directory created...";
fi

##########
## ensures directory is clear before beginning script
if test -f "$file"
then 
        echo "Clearing directory of any past files..."
        sudo rm $file;
fi

##########
## takes picture with webcam if incorrect password is entered
## stores picture in created directory
ts=`date +%s`
ffmpeg -f video4linux2 -s vga -i /dev/video0 -vframes 1 $file
#exit 0  ## NOTE - must exit with status 0

##########
## send $file in email
sudo sendemail -f $SMTPFROM -t $SMTPTO -o tls=yes -a $file -u $SUBJECT -m $MESSAGE -s $SMTPSERVER -xu $SMTPUSER -xp $SMTPPASS

##########

不要介意所有额外的哈希值,只要我的组织方式即可。我确信我还有很多地方可以做得更好,也有很多不必要的事情,但它确实有效!感谢所有的投入!
