關(guān)于Unix/Linux下查看命令行歷史記錄(history/.bash_history)

1.vi .bash_history

關(guān)于.bash_history的配置

export HISTCONTROL=ignoreboth

Don’t save duplicates

export HISTSIZE=10000

這個是針對history命令的設(shè)置，The number of commands to remember in the command history. The default value is 500.

export HISTFILESIZE=10000

這個是針對history文件(.bash_history)的設(shè)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 

以上的關(guān)于history的說明都可以使用man bash查的到,如果想要讓你的配置永久生效，可以把export命令寫到.bash_profile或者全局配置文件/etc/profile里

2.history

模糊查詢，history | grep -i "xxx"

[oracle@bej301441 ~]$ history | grep -i "FND"
   34  2012-07-04 01:29:15 history | grep -i "FND"
   35  2012-07-04 01:29:30 FNDLOAD apps/apps 0 Y DOWNLOAD $FND_TOP/patch/115/import/affrmcus.lct PT_CUSTOM_FUC.ldt FND_FORM_CUSTOM_RULES function_name="INV_INVTOMAI"
   36  2012-07-04 01:29:33 history | grep -i "FND"
[oracle@bej301441 ~]$

如何讓history可以有時間戳顯示

# 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記錄

[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里仍會有歷史記錄

如何不讓系統(tǒng)記錄歷史命令

# export HISTSIZE=0
# history
# [Note that history did not display anything]

3.使用Control+R來搜索命令

命令行中輸入Control+R，然后輸入過往命令的key word，你就很容易找到以前執(zhí)行過的命令了
