1.vi .bash_history
关于.bash_history的配置
export HISTCONTROL=ignoreboth
Don’t save duplicates
export HISTSIZE=10000
这个是针对history命令的设置，The number of commands to remember in the command history. The default value is 500.
export HISTFILESIZE=10000
这个是针对history文件(.bash_history)的设置，The maximum number of lines contained in the history file. When this variable is assigned a value, the his-tory file is truncated, if necessary, by removing the oldest entries, to contain no more than that number of lines. The default value is 500. The history file is also truncated to this size after writing it when an interactive shell exits.
export HISTIGNORE='ls'
A colon-separated list of patterns used to decide which command lines should be saved on the history list.Each pattern is anchored at the beginning of the line and must match the complete line
以上的关于history的说明都可以使用man bash查的到,如果想要让你的配置永久生效，可以把export命令写到.bash_profile或者全局配置文件/etc/profile里
2.history
模糊查询，history | grep -i "xxx"
[oracle@bej301441 ~]$ history | grep -i "FND"
34 2012-07-04 01:29:15 history | grep -i "FND"

36 2012-07-04 01:29:33 history | grep -i "FND"
[oracle@bej301441 ~]$
如何让history可以有时间戳显示
# export HISTTIMEFORMAT='%F %T '
....
1027 2012-07-04 01:12:53 ls /etc/bash*
1028 2012-07-04 01:13:17 vi /etc/bashrc
1029 2012-07-04 01:16:04 history
[oracle@bej301441 ~]$
清除history记录
[oracle@bej301441 ~]$ history -c
[oracle@bej301441 ~]$ history
32 2012-07-04 01:20:40 history
[oracle@bej301441 ~]$
注:清除history之后，.bash_history里仍会有历史记录
如何不让系统记录历史命令
# export HISTSIZE=0
# history
# [Note that history did not display anything]
3.使用Control+R来搜索命令
命令行中输入Control+R，然后输入过往命令的key word，你就很容易找到以前执行过的命令了
