[email protected]:~$ whereis -m ls ls: /usr/share/man/man1/ls.1.gz [email protected]:~$ whereis -m pwdpwd: /usr/share/man/man1/pwd.1.gz

There are three output information
1. The directory where the command itself is located
2. The directory where the source files are located
3. The directory where the Help document is located

Locate is faster than find based on the local computer database (computer disk information). Locate generally updates the database at night, but can also update itself manually

更新数据库后看下： @IdeaPad:~/test# sudo updatedb [email protected]:~/test# locate aobama /root/test/aobama[email protected]:~/test#

Find command full scan, similar to Windows search; slower

Find can be found based on file name
