Linux locate quick search command Introduction

 

It's a year before the New Year. I haven't shared it with you for a long time, and my work is too busy.

 

Anyone using linux will know the find command.

 

The following describes how to use the find command in linux.

 

The following describes a quick search tool locate that supports regular expressions.

 

Generally, linux is installed by default. Do not worry if no default installation is available.

 

Ubuntu: sudo apt-get install locate;

 

Centos: yum-y install mlocate;

 

Working principle: regularly generate data files related to file names through scheduled tasks (usually stored in [/var/lib/mlocate. db]), of course, the scheduled task will not be very real-time, this will cause the software you just installed to not find, at this time you need to use (updatedb) to update the locate data file.

 

 

Usage: locate xx (file name to be searched)-l num (number of rows to be displayed ). Of course, this file name appears too many in the system, you need to use the-l parameter. Or wait for the screen to be refreshed.

 

Regular Expression parameters:-r,-regexp REGEXP

 

Search for a basic regexp REGEXP. No PATTERNs are allowed ifthis option is used, but this option can be specified multiple

Times.

More usage: man locate;
