定位、查找文件

1.which command(在path中找第一个)

[[email protected] /]# which ls
alias ls='ls --color=auto'
	/usr/bin/ls

2.whereis [option]name

[[email protected] /]# whereis ls
ls: /usr/bin/ls /usr/share/man/man1/ls.1.gz /usr/share/man/man1p/ls.1p.gz
[[email protected] /]# whereis -b ls
ls: /usr/bin/ls
[[email protected] /]# whereis -m ls
ls: /usr/share/man/man1/ls.1.gz /usr/share/man/man1p/ls.1p.gz
[[email protected] /]# whereis -s ls
ls:[[email protected] /]# 

3.find path -name [文件名]

[[email protected] 桌面]# ls m*
my  mylove  mysql
[[email protected] /]# find /home/260254/桌面 -name my*
/home/260254/桌面/my
