这样咋整

[aluns]~>cat t.txt
Entries in termcap consist of a number of `:'-separated fields. The first entry for each terminal gives the names that are known for the terminal, separated by `|' characters. The first name given is the most common abbreviation for the terminal. The last name given should be a long name fully identifying the terminal, and all others are understood as synonyms for the terminal name. All names but the last should be in lower case and contain no blanks; the last name may well contain upper

建议用stty+sed

woodie

fold -s -w 90 t.txt|sed 'G'

技安

那个文件、只有一行，

woodie

一行又如何？你试过了吗？

woodie

不会是连这个都不会吧：
old -s -w 90 t.txt|sed 'G' > folded
mv folded t.txt

技安

不是想用什么sed....，而是直接用cat就显示出这个效果，只是想在一行结束的时候，跳到隔一行位置输出。在tput里没找到，再找找。

Sorry！我不知道楼主对sed过敏的。^_^
但非常遗憾，据我所知，cat没有你想要的功能。如果真的如此在意，可以写个简单脚本可以叫做CAT，或jcat之类：
#!/bin/sh
fold -sw90 $* |\
sed G
#end
然后只要打CAT t.txt就行了。

另外，如果你的终端屏幕是正常的大小，请修改上面的90为80。^_^

你咋没明白、我说的意思呢？


这个和t.txt没有关系，我不要一个文本，而是想让所有的输出的东西，都变成那样、包括一个命令

哎～～～、

是把默认的换行符由一个变两个吧?
