Linux/Unix 桌面趣事:文字模式下的 ASCII 艺术与注释绘画
|
||
================================================================================
|
||
boxes 命令不仅是一个文本过滤器,同时是一个很少人知道的有趣工具,它可以在输入的文本或者代码周围框上各种ASCII 艺术画。你可以用它快速创建邮件签名,或者在各种编程语言中留下评论块。这个命令可以在 vim 文本编辑器中使用,但是也可以在各种支持过滤器的文本编辑器中使用,同时也可以在命令行中单独使用。
|
||
|
||
### 任务: 安装 boxes ###

|
||
*图01: Unix / Linux: Boxes 命令来画出各式各样的图案 *
|
||
|
||
#### 怎么样输出所有的图案 ####
|
||
|
||
语法如下:
|
||
|
||
boxes option
|
||
pipe | boxes options
|
||
echo "text" | boxes -d foo
|
||
boxes -l
|
||
|
||
-d 选项用来设置要使用的图案的名字。语法如下:
|
||
|
||
echo "Text" | boxes -d design
|
||
pipe | boxes -d desig
|
||
|
||
-l 选项列出所有图案。它显示了在配置文件中的所有的框线设计图,同时也显示关于其创作者的信息。
|
||
|
||
boxes -l
|
||
boxes -l | more
|
||
boxes -l | less

### 在使用 vi/vim 文本编辑器时如何通过 boxes 过滤文本? ###
|
||
|
||
你可以在 vi 或 vim 中使用任何外部命令,比如在这个例子中,[插入当前日期和时间][4],输入:
|
||
|
||
!!date
|
||
|
||
或者
|
||
|
||
:r !date
|
||
|
||
你需要在 vim 中输入以上命令来读取 date 命令的输出,这将在当前行后面加入日期和时分秒:
|
||
|
||
Tue Jun 12 00:05:38 IST 2012
|
||
|
||
你可以用 boxes 命令做到同样的功能。如下创建一个作为示例的 shell 脚本或者c程序:
|
||
|
||
|
||
#!/bin/bash
|
||
Purpose: Backup mysql database to remote server.
|
||

||
Last updated on: Tue Jun, 12 2012
|
||
|
||
现在输入如下(将光标移到第二行,也就是以“Purpose: ...”开头的行)
|
||
|
||
3!!boxes
|
||
|
||
瞧,你就会看到如下的输出 :
|
||
|
||
#!/bin/bash
|
||
/****************************************************/
|
||
/* Purpose: Backup mysql database to remote server. */
