在linux下使用sqlplus历史回调功能

当在Linux Shell中运行SQL*Plus的时候，并不提供浏览历史命令行的功能。相反的，在Windows操作系统上，当在DOS命令窗口中运行 SQL*Plus的时候，可以使用向上，向下键来跳回之前已经执行过的SQL语句。你可以根据需要修改他们，然后按[Enter]重新提交执行。

为了在Linux中达到同样的目的，你可以安装rlwrap，这个程式本身是个Shell，可以运行任何你提供给它的命令包括参数，并添加命令历史浏览功能。 The rlwrap program is under the GPL license。

1：安装

rlwrap-0.28.tar.gz下载地址:http://utopia.knoware.nl/~hlub/uck/rlwrap/

1):解压缩安装文件

[oracle@Channel-MQ3 ~]$gunzip rlwrap-0.28.tar.gz

[oracle@Channel-MQ3 ~]$tar xvf rlwrap-0.28.tar

2):切换到root用户，执行下面的命令

[root@Channel-MQ3 ~]# cd /home/oracle/rlwrap-0.28

[root@Channel-MQ3 rlwrap-0.28]# ls

[root@Channel-MQ3 rlwrap-0.28]#./configure

[root@Channel-MQ3 rlwrap-0.28]#make

[root@Channel-MQ3 rlwrap-0.28]#make install

2:使用

$ rlwrap [-options] <command> <args>

[oracle@Channel-MQ3 ~]$ which rlwrap

/usr/local/bin/rlwrap

[oracle@Channel-MQ3 ~]$ rlwrap sqlplus / as sysdba

另外rlwrap还有很多选项可以设置

eg:

−l, −−logfile file

Append command’s output (including echo’ed user input) to file (creating file when it doesn’t exist).

测试如下

[oracle@Channel-MQ3 ~]$ rlwrap -l benbotest.log sqlplus / as sysdba

当然，如果嫌每次敲rlwrap不爽，可以在/etc/profile或者自己的~/.bashrc里面添加alias sqlplus='rlwrap sqlplus'。其他发行版的朋友可以选择rpm包或者干脆从源码自己编译。

其它选择参考manpage.
