linux查找文件命令find

想要在Linux下面，找之前不知道放到哪里的一个tomcat的文件。

【折腾过程】

1.最后是参考：

linux查找文件命令find – 发芽的石头 – 博客频道 – CSDN.NET

去搜：

root@bogon:openfire# find / -name '*tomcat*'/usr/local/tomcat1/usr/local/tomcat1/conf/tomcat-users.xml/usr/local/tomcat1/lib/tomcat-util.jar/usr/local/tomcat1/lib/tomcat-i18n-ja.jar/usr/local/tomcat1/lib/tomcat-coyote.jar/usr/local/tomcat1/lib/tomcat-i18n-fr.jar/usr/local/tomcat1/lib/tomcat7-websocket.jar/usr/local/tomcat1/lib/tomcat-dbcp.jar/usr/local/tomcat1/lib/tomcat-i18n-es.jar/usr/local/tomcat1/lib/tomcat-jdbc.jar/usr/local/tomcat1/lib/tomcat-api.jar/usr/local/tomcat1/webapps/manager/images/tomcat.gif/usr/local/tomcat1/webapps/ROOT/tomcat.css/usr/local/tomcat1/webapps/ROOT/tomcat.gif/usr/local/tomcat1/webapps/ROOT/tomcat-power.gif/usr/local/tomcat1/webapps/ROOT/tomcat.svg/usr/local/tomcat1/webapps/ROOT/tomcat.png/usr/local/tomcat1/webapps/host-manager/images/tomcat.gif/usr/local/tomcat1/webapps/docs/images/tomcat.gif/usr/local/tomcat1/webapps/docs/images/tomcat.svg/usr/local/tomcat1/webapps/docs/appdev/sample/web/images/tomcat.gif/usr/local/tomcat1/bin/tomcat-native.tar.gz/usr/local/tomcat1/bin/tomcat-juli.jar/usr/sbin/tomcat6/usr/sbin/dtomcat6/usr/bin/tomcat6-digest/usr/bin/tomcat6-tool-wrapper/usr/share/tomcat6/usr/share/tomcat6/bin/tomcat-juli.jar/usr/share/tomcat6/bin/tomcat-juli-6.0.24.jar/usr/share/selinux/devel/include/services/tomcat.if/usr/share/selinux/targeted/tomcat.pp.bz2/usr/share/doc/apache-tomcat-apis-0.1/usr/share/doc/tomcat6-6.0.24/usr/share/java/tomcat6/usr/share/java/tomcat6/tomcat-i18n-fr-6.0.24.jar/usr/share/java/tomcat6/tomcat-i18n-ja.jar/usr/share/java/tomcat6/tomcat-juli.jar/usr/share/java/tomcat6/tomcat-coyote.jar/usr/share/java/tomcat6/tomcat-i18n-fr.jar/usr/share/java/tomcat6/tomcat6-jsp-2.1-api-6.0.24.jar/usr/share/java/tomcat6/tomcat-i18n-ja-6.0.24.jar/usr/share/java/tomcat6/tomcat6-el-2.1-api-6.0.24.jar/usr/share/java/tomcat6/tomcat6-servlet-2.5-api-6.0.24.jar/usr/share/java/tomcat6/tomcat-coyote-6.0.24.jar/usr/share/java/tomcat6/tomcat-i18n-es.jar/usr/share/java/tomcat6/extras/tomcat-juli.jar/usr/share/java/tomcat6/extras/tomcat-juli-adapters.jar/usr/share/java/tomcat6/tomcat-i18n-es-6.0.24.jar/usr/share/java/apache-tomcat-apis/usr/share/java/apache-tomcat-apis/tomcat-jsp2.1-api.jar/usr/share/java/apache-tomcat-apis/tomcat-servlet2.5-api.jar/usr/share/java/apache-tomcat-apis/tomcat-jsp2.0-api.jar/usr/share/java/apache-tomcat-apis/tomcat-servlet2.4-api.jar/usr/share/java/tomcat6-servlet-2.5-api.jar/usr/share/java/tomcat6-jsp-2.1-api-6.0.24.jar/usr/share/java/tomcat6-el-2.1-api-6.0.24.jar/usr/share/java/tomcat6-servlet-2.5-api-6.0.24.jar/usr/share/java/tomcat6-el-2.1-api.jar/usr/share/java/tomcat6-jsp-2.1-api.jar/var/lib/tomcat6/var/lib/tomcat6/webapps/manager/images/tomcat.gif/var/lib/tomcat6/webapps/sample/images/tomcat.gif/var/lib/tomcat6/webapps/ROOT/tomcat.gif/var/lib/tomcat6/webapps/ROOT/tomcat-power.gif/var/lib/tomcat6/webapps/ROOT/tomcat.svg/var/lib/tomcat6/webapps/host-manager/images/tomcat.gif/var/lib/yum/yumdb/a/e35f1b8f8c6e2f285fc0214286e0b03beaf5e852-apache-tomcat-apis-0.1-1.el6-noarch/var/lib/yum/yumdb/t/0c3c81b5aaba908a837902db4cba8076f2e7cc5d-tomcat6-lib-6.0.24-83.el6_6-x86_64/var/lib/yum/yumdb/t/02426ee47b3a07f259586c51c37c8359f1c7627d-tomcat6-servlet-2.5-api-6.0.24-83.el6_6-x86_64/var/lib/yum/yumdb/t/b60f2e9f994eb122122cf02114b51164ff7dd4c3-tomcat6-admin-webapps-6.0.24-83.el6_6-x86_64/var/lib/yum/yumdb/t/f3acc3eab248f6f1009abdc219c1d3bea9a025ec-tomcat6-webapps-6.0.24-83.el6_6-x86_64/var/lib/yum/yumdb/t/508295a2c951bee066ef29f46f78a02b6c50a11c-tomcat6-el-2.1-api-6.0.24-83.el6_6-x86_64/var/lib/yum/yumdb/t/bc2836feb5319c5623fe1c243697dba038203642-tomcat6-6.0.24-83.el6_6-x86_64/var/lib/yum/yumdb/t/9cd8fa43f523ea3019f4e806f1cb75cbd65343df-tomcat6-jsp-2.1-api-6.0.24-83.el6_6-x86_64/var/run/tomcat6.pid/var/log/tomcat6/var/log/tomcat6-initd.log/var/lock/subsys/tomcat6/var/cache/tomcat6/etc/tomcat6/etc/tomcat6/tomcat-users.xml/etc/tomcat6/tomcat6.conf/etc/selinux/targeted/modules/active/modules/tomcat.pp/etc/rc.d/init.d/tomcat6/etc/rc.d/rc4.d/K20tomcat6/etc/rc.d/rc2.d/K20tomcat6/etc/rc.d/rc1.d/K20tomcat6/etc/rc.d/rc6.d/K20tomcat6/etc/rc.d/rc3.d/K20tomcat6/etc/rc.d/rc5.d/K20tomcat6/etc/rc.d/rc0.d/K20tomcat6/etc/logrotate.d/tomcat6/etc/sysconfig/tomcat6/tmp/hsperfdata_tomcatroot@bogon:openfire#

2.后来又去试试其他的：

如图：

其中的^C是发现很多文件没有权限，所以Ctrl+C去终止了。

然后加上sudo，就有权限去搜索了。

【总结】

想要在Linux下面查找文件，尤其是只知道部分文件名，关键字，则可以去用：

find 路径 -name ‘*要搜的关键字*’

比如：

find / -name '*tomcat*'

即可。

如果要搜的路径或文件涉及到没有权限，即出现Permission denied，则可以加上前缀sudo，比如：

sudo find / -name '*dovecot.pem*'

即可。
