修改 history

history 默认 500 条, 经常使用命令行会不够用, 可以做如下修改:

export HISTFILESIZE=10000000
export HISTSIZE=10000000.

HISTFILESIZE 与 HISTSIZE 的区别:

• HISTFILESIZE 决定在 history 文件中能保存多少行;
• HISTSIZE 能在内存中保存多少行.

HISTFILESIZE determines the number of lines to keep in the history file while HISTSIZE determines the number of lines to keep in memory. Both default to 500 Execute echo $HISTFILESIZE $HISTSIZE before you make the change and then again after. You should see 10000000 500 first then 10000000 10000000 after.
