示例
查看 dnf makecache; 命令修改了哪些文件
[root@dameng linuxscript]# T="$(date "+%F %T.%N")"; dnf makecache; find / -xdev -newermt "$T" CentOS-8.5.2111 - Base - mirrors.aliyun.com 279 kB/s | 3.9 kB 00:00 CentOS-8.5.2111 - Extras - mirrors.aliyun.com 119 kB/s | 1.5 kB 00:00 CentOS-8.5.2111 - AppStream - mirrors.aliyun.com 331 kB/s | 4.3 kB 00:00 Metadata cache created. /tmp /var/log/dnf.log /var/log/dnf.librepo.log /var/log/dnf.rpm.log /var/log/hawkey.log /var/lib/rpm/__db.002 /var/lib/rpm/__db.001 /var/lib/rpm/__db.003 /var/cache/dnf /var/cache/dnf/extras-e503dfa263573efa/repodata/86501a1d822eea269ca494f23adb73be14166b426a1a2bcdaaacf5cef2859b5e-primary.xml.gz /var/cache/dnf/AppStream-c40f4caedb6d900a/repodata/d8472d61c5e53a3e9cbffb68e0dddbd04a07c2b7d864b07ddd211c6ad1380c6e-primary.xml.gz /var/cache/dnf/base-c446c86678567d00/repodata/ca039bbfe8297c592cdc0e7251689f5d597771d39b2ddede01106ad0a7f0ba60-primary.xml.gz /var/cache/dnf/expired_repos.json
验证
[root@dameng linuxscript]# T="$(date "+%F %T.%N")"; tarthis ;find / -xdev -newermt "$T" /root/#linuxscript#-2024-12-16.tgz /tmp /usr/local/uniagent/log/uniagent.log /var/log/hostguard/hostwatch.log
延伸方法
查看某脚本 script.sh 修改的文件
[root@dameng ~]# T="$(date "+%F %T.%N")"; ./script.sh; find / -xdev -newermt "$T"
例如：
[root@dameng linuxscript]# T="$(date "+%F %T.%N")"; ./file_size_distribution.sh /dmbak/; find / -xdev -newermt "$T" From To Count 1KB 10KB 2 10KB 100KB 5 100KB 1MB 13 1MB 10MB 2 10MB 100MB 1 100MB 1GB 1 Total: 281.9 MB in 24 files /usr/local/hostguard/run/heartbeat.tick /var/log/hostguard/containers.log /var/log/hostguard/hostguard.log
由于上述脚本 file_size_distribution.sh 没有操作文件的步骤，所以只列出了系统执行日志变化的文件。
