引用命令行 ![!|[?]string|[-]number]
:[n|x-y|^|$|*|n*|%]:[h|t|r|e|p|s|g] -------选择word---- ----修饰符-----
!! ---上一条命令 !cat 以cat开头的命令 [oracle@rh64 ~]$ !cat cat /etc/passwd root:x:0:0:root:/root:/bin/bash bin:x:1:1:bin:/bin:/sbin/nologin daemon:x:2:2:daemon:/sbin:/sbin/nologin adm:x:3:4:adm:/var/adm:/sbin/nologin
!?cat 含cat的命令 [oracle@rh64 ~]$ !?cat cat /etc/passwd root:x:0:0:root:/root:/bin/bash bin:x:1:1:bin:/bin:/sbin/nologin daemon:x:2:2:daemon:/sbin:/sbin/nolog
!n 第 n 个命令 !-n 倒数第 n 个命令
!$ 上条命令最后一位
!^ 上条命令第一位
!:n 上条命令第 n 位
!:x-y 上条命令 x - y
!:n* 上条 n 到最后
!* 上条所有参数
:h 选取路径开头
:t 选取路径结尾
:r 选取文件名 [oracle@rh64 ~]$ echo a.txt a.txt [oracle@rh64 ~]$ !$:t a.txt -bash: a.txt: command not found [oracle@rh64 ~]$ echo !$:r echo a a :e 选取扩展名 [oracle@rh64 ~]$ echo abc.jpg abc.jpg [oracle@rh64 ~]$ echo !$:e echo .jpg .jpg
:p 打印命令行 [oracle@rh64 ~]$ !e:p echo .jpg [oracle@rh64 ~]
:s 做替换 % echo this that % !:s/is/e echo the that 惯用法: ^is^e [oracle@rh64 ~]$ echo this that this that [oracle@rh64 ~]$ !:s/is/e echo the that the that [oracle@rh64 ~]$ ^is^e -bash: :s^is^e: substitution failed [oracle@rh64 ~]$ echo this that this that [oracle@rh64 ~]$ ^is^e echo the that the that [oracle@rh64 ~]$
:g 做全局替换 [oracle@rh64 ~]$ echo abcd abef abcd abef [oracle@rh64 ~]$ !:gs/ab/cd echo cdcd cdef cdcd cdef [oracle@rh64 ~]$
