设置Linux环境的欢迎登陆信息

1、编辑/etc/profile文件添加如下内容：

for i in /etc/profile.d/*.sh ; do
    if [ -r "$i" ]; then
        if [ "${-#*i}" != "$-" ]; then
            . "$i"
        else
            . "$i" >/dev/null 2>&1
        fi
    fi
done

　　

2、在/etc/profile.d放置相关脚本

[root@typhoeus79 ice_test_m profile.d]# ll
