Posted 2020-11-11 xbwlinux

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}

[[email protected] ~]# echo stu{01..10}

stu01 stu02 stu03 stu04 stu05 stu06 stu07 stu08 stu09 stu10

[[email protected] ~]# echo 20{01..10}

2001 2002 2003 2004 2005 2006 2007 2008 2009 2010

#通过{}

[[email protected] ~]# 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

[[email protected] ~]# echo {a c f}

{a c f}

[[email protected] ~]# echo {a,c,f}

a c f

[[email protected] ~]# echo A{B,C}

AB AC

[[email protected] ~]# echo A{,C}

A AC

[[email protected] ~]# echo oldboy.txt{,.bak}

oldboy.txt oldboy.txt.bak

[[email protected] ~]# touch oldboy.txt

[[email protected] ~]# cp oldboy.txt{,.bak}

cp: overwrite `oldboy.txt.bak‘? y

[[email protected] ~]# ls -l oldboy.txt*

[[email protected] ~]# 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

[[email protected] ~]#

[[email protected] ~]# #cp oldboy.txt{,.bak}

[[email protected] ~]# echo oldboy.txt{,.bak}

oldboy.txt oldboy.txt.bak

[[email protected] ~]# echo A{,C}

A AC
