Question

我是bash脚本的新手，尝试运行下面的脚本，我应该检查系统百分比并使用case命令运行另一个脚本

#!/bin/bash
clear
echo "will able to see the percentage of hard disk"
for line in $(</home/AAA/BBB/CCCC/pre-prod1.txt)
do
ssh $line 'hostname -s; df -P |grep '/XXX/CCCC' | awk '"'"'{print $5}'"'"
echo '--------------------------------------------------------------------------------------------'
usage = $(< 'hostname -s; df -P |grep '/opt/splunk' | awk '"'"'{print $5}'"'" )
#if [$? -gt 65]
#   then
#        '/home/ BB/DD /remove_old_data.sh'
#
#fi
done

case $usage in
     50% - 2880 minutes) echo "when the hard disk is above 50%"
         /home/BB/DD/remove_old_data.sh 2880
          ;;
     50-75% - 1440 minutes) echo "when the hard disk space is above 75%"
         /home/ BB/DD /remove_old_data.sh 1440
         ;;
     75-90% - 720 minutes) echo "when the hard disk space is above 90%"
        /home/ BB/DD /remove_old_data.sh 720
        ;;
     >90% - 360 minutes) echo "when the hard disk space above 91%"
        /home/ BB/DD /remove_old_data.sh 360
       ;;
esac

我收到以下错误：

./checksize1.sh: line 9: hostname -s; df -P |grep /opt/splunk | awk '{print $5}': No such file or directory
./checksize1.sh: line 9: usage: command not found
./checksize1.sh: line 19: syntax error near unexpected token `-'
./checksize1.sh: line 19: `     50% - 2880 minutes) echo "when the hard disk is above 50%"'

我在您的脚本中做了一些修改，它应该满足您的要求：

#!/bin/bash
clear
echo "will able to see the percentage of hard disk"
for line in $(cat /home/AAA/BBB/CCCC/pre-prod1.txt)
do 
usage=$(ssh $line "df -P |grep '/opt/splunk'" | awk '{print $5}' | cut -d'%' -f1)
echo '-------------------------------------------------------------------------'
#if [$? -gt 65]
#   then
#        '/home/ BB/DD /remove_old_data.sh'
#
#fi
echo "Machine name: $( echo $line | cut -d'@' -f2 )"
    case $usage in
         50 ) echo "when the hard disk is above 50%"
            /home/BB/DD/remove_old_data.sh 2880
            ;;
         [5-6][0-9]|7[0-5] ) echo "when the hard disk space is above 75%"
             /home/BB/DD/remove_old_data.sh 1440
            ;;
         7[6-9]|8[0-9]|90 ) echo "when the hard disk space is above 90%"
            /home/BB/DD/remove_old_data.sh 720
            ;;
         9[1-9]|100 ) echo "when the hard disk space above 91%"
            /home/BB/DD/remove_old_data.sh 360
            ;;
          * ) echo "Disk space is less than 50%"
            ;;
    esac
done

文件/home/AAA/BBB/CCCC/pre-prod1.txt应包含服务器的主机名，如下所示：

user@server1
user@server2
user@server3

请检查此信息，如果您的要求不同，请告知我们。

注意：我更新了脚本。以前，我已将分区设为/dev/sda1，但是，我相信您正在尝试获取分区/opt/splunk的磁盘使用情况。我已经对我的脚本进行了更改，这应该可以正常工作。如果您尝试获取服务器上任何其他分区的磁盘使用情况，请在脚本中更新以下行：

usage=$(ssh $line "df -P |grep '/opt/splunk'" | awk '{print $5}' | cut -d'%' -f1)

我已经在测试服务器上测试了脚本并找到了以下结果。

[12:41]✓ -> bash test.sh 
will able to see the percentage of hard disk
-------------------------------------------------------------------------
Server: server1 
82
when the hard disk space is above 90%
-------------------------------------------------------------------------
Server: server2
87
when the hard disk space is above 90%
-------------------------------------------------------------------------
Server: server3
50
when the hard disk is above 50%

检查文件系统百分比并使用case命令运行脚本
