我使用的是Ubuntu 10.04,,安装rlwrap的方式采用的是:sudo apt-get install rlwrap。

使用方式是:rlwrap sqlplus,进入后就可以使用方向键了。一种不需要输入rlwrap的方式是修改自己的bashrc,添加alias sqlplus='rlwrap sqlplus',使其生效后,以后就不再需要输入rlwrap就可以使用方向键了。

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。

Solve the problem of garbled display of graphs and charts on Zabbix Chinese monitoring server Solve the problem of garbled display of graphs and charts on Zabbix Chinese monitoring server Jul 31, 2024 pm 02:10 PM

Zabbix's support for Chinese is not very good, but sometimes we still choose Chinese for management purposes. In the web interface monitored by Zabbix, the Chinese under the graphic icon will display small squares. This is incorrect and requires downloading fonts. For example, "Microsoft Yahei", "Microsoft Yahei.ttf" is named "msyh.ttf", upload the downloaded font to /zabbix/fonts/fonts and modify the two characters in the /zabbix/include/defines.inc.php file at define('ZBX_GRAPH_FONT_NAME','DejaVuSans');define('ZBX_FONT_NAME'

toss! Running DOS on Raspberry Pi toss! Running DOS on Raspberry Pi Jul 19, 2024 pm 05:23 PM

Different CPU architectures mean that running DOS on the Raspberry Pi is not easy, but it is not much trouble. FreeDOS may be familiar to everyone. It is a complete, free and well-compatible operating system for DOS. It can run some older DOS games or commercial software, and can also develop embedded applications. As long as the program can run on MS-DOS, it can run on FreeDOS. As the initiator and project coordinator of FreeDOS, many users will ask me questions as an insider. The question I get asked most often is: "Can FreeDOS run on a Raspberry Pi?" This question is not surprising. After all, Linux runs very well on the Raspberry Pi
