linux基础学习-10.2-通配符回顾

1、 * 所有 任何东西

以.txt结尾 *.txt

以.log结尾 *.log

系统中以ls开头的文件。

find / -type f -name "ls*"

找出系统中文件名包含oldboy的文件。

find / -type f -name "*oldboy*"

2、{} 生成序列

echo {1..10}

echo {10..1}

echo {01..10}

echo {01..100}

echo {a..c}

echo {a..z}

echo {A..Z}

[root@oldboyedu42-lnb ~]# echo stu{01..10}

stu01 stu02 stu03 stu04 stu05 stu06 stu07 stu08 stu09 stu10

[root@oldboyedu42-lnb ~]# echo 20{01..10}

2001 2002 2003 2004 2005 2006 2007 2008 2009 2010

#通过{}

[root@oldboyedu42-lnb ~]# echo {a..z}

a b c d e f g h i j k l m n o p q r s t u v w x y z

[root@oldboyedu42-lnb ~]# echo {a c f}

{a c f}

[root@oldboyedu42-lnb ~]# echo {a,c,f}

a c f

[root@oldboyedu42-lnb ~]# echo A{B,C}

AB AC

[root@oldboyedu42-lnb ~]# echo A{,C}

A AC

[root@oldboyedu42-lnb ~]# echo oldboy.txt{,.bak}

oldboy.txt oldboy.txt.bak

[root@oldboyedu42-lnb ~]# touch oldboy.txt

[root@oldboyedu42-lnb ~]# cp oldboy.txt{,.bak}

cp: overwrite `oldboy.txt.bak'? y

[root@oldboyedu42-lnb ~]# ls -l oldboy.txt*

[root@oldboyedu42-lnb ~]# ls -l oldboy.txt*

-rw-r--r-- 3 root root 0 Nov 11 23:50 oldboy.txt

-rw-r--r--. 1 root root 0 Nov 11 23:50 oldboy.txt.bak

-rw-r--r-- 3 root root 0 Nov 11 23:50 oldboy.txt-hard

[root@oldboyedu42-lnb ~]#

[root@oldboyedu42-lnb ~]# #cp oldboy.txt{,.bak}

[root@oldboyedu42-lnb ~]# echo oldboy.txt{,.bak}

oldboy.txt oldboy.txt.bak

[root@oldboyedu42-lnb ~]# echo A{,C}

A AC
