【转载】CentOS查找命令

1、使用which命令搜索，如果没搜到？扩大范围搜：whereis

[root@ctyun ~]# which gcc
/usr/bin/gcc
[root@ctyun ~]# whereis gcc
gcc: /usr/bin/gcc /usr/lib/gcc /usr/libexec/gcc /usr/share/man/man1/gcc.1.gz

2、使用本地文件索引搜索，搜索更加精准和有效

一般centos下没有安装locate命令

yum -y install mlocate

更新下索引

updatedb

搜索试试

[root@ctyun ~]# locate signal.h
/usr/include/signal.h
/usr/include/asm/signal.h
/usr/include/asm-generic/signal.h
/usr/include/linux/signal.h
/usr/include/sys/signal.h

3、查询已经安装的包名称

rpm包安装的

rpm -qa | grep "软件包名称“

deb包安装的

dpkg -l | grep "软件包名称"

4、查询已经的软件都包含哪些文件？

[root@ctyun ~]# rpm -ql php
/etc/httpd/conf.d/php.conf
/usr/lib64/httpd/modules/libphp5-zts.so
/usr/lib64/httpd/modules/libphp5.so
/var/lib/php/session
/var/lib/php/wsdlcache
/var/www/icons/php.gif

5、查看yum安装过那些软件包？

yum list installed | grep "软件包名称"

6、使用基本的find命令搜索

[root@ctyun ~]# find / -name nginx
/usr/share/nginx
/usr/sbin/nginx
/etc/logrotate.d/nginx
/etc/sysconfig/nginx
/etc/rc.d/init.d/nginx
/etc/nginx
/var/cache/nginx
/var/cache/yum/x86_64/6/nginx
/var/lib/yum/repos/x86_64/6/nginx
/var/log/nginx
