【背景】

想要在Linux下面，找之前不知道放到哪里的一個tomcat的文件。

【折騰過程】

1.最后是參考：

去搜：root@bogon:openfire# find / -name '*tomcat*'

^C

crifan@crifan:~$ sudo find / -name '*dovecot.pem*'

[sudo] password for crifan:

/home/crifan/mail_server/dovecot/certs/dovecot.pem

/home/crifan/mail_server/dovecot/private/dovecot.pem

/etc/pki/dovecot/certs/dovecot.pem

/etc/pki/dovecot/private/dovecot.pem

如圖：

其中的^C是發(fā)現(xiàn)很多文件沒有權(quán)限，所以Ctrl+C去終止了。

然后加上sudo，就有權(quán)限去搜索了。

【總結(jié)】

想要在Linux下面查找文件，尤其是只知道部分文件名，關(guān)鍵字，則可以去用：find 路徑 -name ‘*要搜的關(guān)鍵字*’

比如：find / -name '*tomcat*'

即可。

如果要搜的路徑或文件涉及到?jīng)]有權(quán)限，即出現(xiàn)Permission denied，則可以加上前綴sudo，比如：sudo find / -name '*dovecot.pem*'

即可。
