我想知道通过命令行将磁盘置于待机模式的命令是什么。我的目标是制作一个处理这种情况的特定脚本。

提前致谢。

Bash 脚本 - 删除所有早于的文件，但出于安全原因保留一个

2

我写了一个脚本：

#!/bin/bash
dir=/opt/bla/myfiles
# Check disk usage usep=$(df -H | grep /dev/sda3 | awk '{print $5}' | cut -d '%' -f1)   if [ $usep -ge 90 ]; then
    echo "$(date) Running out of space in /dev/sda3 with $usep percent - so deleting action is taking!" >> /var/log/messages &&
        find $dir/releases/* -mtime +3 -exec rm {} \; else
        echo "$(date) Disk space is $usep percent - no action required!" /var/log/messages   fi

效果很好。但我现在需要更高级的方法。如您所见，它会删除 dir 中超过 3 天的所有文件。我有很多版本，例如：1.31.1 1.31.2 1.31.3 ...... 1.31.150 1.32.1 1.32.2

等等。我想从主要版本 1.31/1.32 中删除除最后一个版本之外的所有版本。如何？它不能是静态名称，因为有一天它会是 2.32.150

sed 字符 (") 不会通过循环

1

我编写了某种脚本，它从数组中获取字符串并在文件中重放它。这里的问题是特殊字符不会通过。有任何想法吗？

#!/bin/bash/
NewParameters=(
scservice.memberServiceEndpoint="http://mywebhere.com"
scservice.memberServiceConpoint="http://example.com"
play.modules.disabled += "play.data.format.FormattersModule"
)

file=/home/conf.conf

for i in "${NewParameters[@]}"                                                           
do
     before=$(printf "%s\n" $i | awk -F'=' '{print $1}')                              
        after=$(printf "%s\n" $i | awk -F'=' '{print $2}')                               
            sed -i "s@$before=.*@$before=$after@g" $file
done

输出结果：

scservice.memberServiceEndpoint=http://mywebhere.com
scservice.memberServiceConpoint=http://example.com
play.modules.disabled += play.data.format.FormattersModule
