把man手册打印出来看的方法

col命令蛮好用的
COL(1) BSD General Commands Manual COL(1)
NAME
col - filter reverse line feeds from input
SYNOPSIS
col [-bfpx] [-l num]
DESCRIPTION
Col filters out reverse (and half reverse) line feeds so the output is in the correct order with only for-
ward and half forward line feeds, and replaces white-space characters with tabs where possible. This can
be useful in processing the output of nroff(1) and tbl(1).
Col reads from standard input and writes to standard output.
The options are as follows:
-b Do not output any backspaces, printing only the last character written to each column position.
-f Forward half line feeds are permitted (猬茆fine猬"猬" mode). Normally characters printed on a half line
boundary are printed on the following line.
-p Force unknown control sequences to be passed through unchanged. Normally, col will filter out any
control sequences from the input other than those recognized and interpreted by itself, which are
listed below.
-x Output multiple spaces instead of tabs.
-lnum Buffer at least num lines in memory. By default, 128 lines are buffered.

如果我们要把某个程序的man手册打印出来，可以这样
man ettercap |col -b >ettercap_man.txt
这样就可以再加工并打印出来了
哈哈

Avril Lavigne——I Will Be (一直很喜欢这首）

Avril Lavigne不对外公开的单曲“I Will Be”只有美国的歌迷在iTunes网站上付费下载艾薇儿新专辑《The Best Damn Thing》后才可以收听，并不对外公开。确实好听呀。

I Will Be
There's nothin' I could say to you
Nothin' I could ever do to make you see
What you mean to me
All the pain, the tears I cried
Still, you never said good-bye
And now I know
How far you'd go
I know I let you down
But it's not like that now
This time I'll never let you go
[Chorus:]
I will be all that you want
And get myself together
'Cause you keep me from falling apart
All my life
I'll be with you forever
To get you through the day
And make everything okay
I thought that I had everything
I didn't know what life could bring
But now I see
Honestly
You're the one thing I got right
The only one I let inside
Now I can breathe
'Cause you're here with me
And if I let you down
I'll turn it all around
'Cause I will never let you go
[Chorus]
'Cause without you
I can't sleep
I'm not gonna ever, ever let you leave
You're all I got
You're all I want
Yeah
And without you I don't know what I'd do
I could never ever live a day without you here
With me
Do you see?
You're all I need
