linux下sqlplus调出历史命令--rlwrap介绍

原创 Linux操作系统 作者:jolly10 时间:2008-07-21 13:53:48 0 删除 编辑
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。[@more@]


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/

(现是已升级到0.30了)
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
aclocal.m4 completions configure INSTALL README TODO
AUTHORS config.h configure.ac Makefile src tools
bash30-005.patch config.h.in COPYING Makefile.am stamp-h1
BUGS config.log distribution Makefile.in test
ChangeLog config.status doc NEWS test.log
[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]
[oracle@Channel-MQ3 ~]$ which rlwrap
/usr/local/bin/rlwrap
[oracle@Channel-MQ3 ~]$ rlwrap sqlplus / as sysdba
