基线脚本执行时报perl: command not found

现象

某次基线安全检查，执行脚本是，报错:
86c221be-6ab2-ef53-1589-fe16877914f4.sh: line 32: perl: command not found
环境：CentOS Linux release 7.4.1708 (Core)

原因：

脚本内容如下:

#!/bin/sh
[ $# -ne 2 ] && { 
 echo "Usage: sh 86c221be-6ab2-ef53-1589-fe16877914f4.sh  <SU用户(SU或高权限用户)> <SU密码>";
 exit 1;
}
# 获取当前路径

pathname=`pwd`

# 执行pl脚本
perl $pathname/86c221be-6ab2-ef53-1589-fe16877914f4.pl "${1}" "${2}"

可知环境中没有perl解释器，故报上述错误，安装即可。

处理：

yum -y install perl perl-devel
其中，perl-devel是perl开发环境依赖包，linux中，很多*-devel结尾都是相关环境的开发包，其内主要包括一些头文件和静态链接库。

再次执行成功：
