1. a2p 將awk 腳本轉化為perl 腳本命令
轉化後的結果並不一定可靠，需要人工干預.
[root@jjy ~/q/data/hongkongAndMacaoPoint/poi]# cat awkTest.sh
#!/bin/bash
echo $1
awk '{for(i=0; i < NF; i++){ print $i}}' $1
[root@jjy ~/q/data/hongkongAndMacaoPoint/poi]# a2p -o awkTest.sh perlTest.pl
Unrecognized character ' in file awkTest.sh line 3--ignoring.
Unrecognized character ' in file awkTest.sh line 3--ignoring.
#!/usr/bin/perl
eval 'exec /usr/bin/perl -S $0 ${1+"$@"}'
if $running_under_some_shell;
# this emulates #! processing on NIH machines.
# (remove #! line above if indigestible)
eval '$'.$1.'$2;' while $ARGV[0] =~ /^([A-Za-z_0-9]+=)(.*)/ && shift;
# process any FOO=bar switches
#!/bin/bash
$, = ' '; # set output field separator
$\ = "\n"; # set output record separator
while (<>) {
chomp; # strip record separator
@Fld = split(' ', $_, -1);
print $_ if $echo . $Fld[(1)-1];
if ($awk) {
for ($i = 0; $i < ($#Fld+1); $i++) {
print $Fld[$i];
}
}
print $_ if $Fld[(1)-1];
}
[root@jjy ~/q/data/tmp_data]# a2ping --bboxfrom=compute-gs /notSolidHd/learing_document/shell12.pdf xx.eps
接受輸入格式： PS (PostScript), EPS, PDF, PNG, JPEG, TIFF, PNM, BMP, GIF, LBM, XPM, PCX, TGA.
接受輸出格式: EPS, PCL5, PDF, PDF1, PBM, PGM, PPM, PS, markedEPS, markedPS, PNG, XWD, BMP, TIFF, JPEG, GIF, XPM.

3. a2ps設置打印如何在打印頁上顯示文本或圖形。
4.a2x 將asciidoc 文檔轉化為其它格式
A DocBook toolchain manager that translates an AsciiDoc text file SOURCE_FILE to PDF, EPUB, DVI, PS, LaTeX, XHTML (single page or chunked), man page, HTML Help or plain text formats using asciidoc(1) and other applications (see REQUISITES section). SOURCE_FILE can also be a DocBook file with an .xml extension
[root@jjy ~/q/data/tmp_data]# cat minimal-book.txt
= The Book Title
== The first chapter
Nec vitae mus fringilla eu vel pede sed pellentesque. Nascetur fugiat
nobis. Eu felis id mauris sollicitudin ut. Sem volutpat feugiat.
Ornare convallis urna vitae.
Nec mauris sed aliquam nam mauris dolor lorem imperdiet.
== The second chapter
Ut suspendisse nulla. Auctor felis facilisis. Rutrum vivamus nec
lectus porttitor dui dapibus eu ridiculus tempor sodales et. Sit a
cras. Id tellus cubilia erat.
Quisque nullam et. Blandit dui tempor. Posuere in elit diam egestas
sem vivamus vel ac.
轉化為pdf格式
[root@jjy ~/q/data/tmp_data]# a2x -fpdf minimal-book.txt
5. a2x.py 與a2x一樣， 只不過為python版本
首先介紹一下aalib
aalib 是把所有的圖形轉換成ascii碼的庫文件.
AAlib is a software library which allows applications to automatically convert still and moving images into ASCII art.
6. aafire , 在terminal中顯示一團火焰
7. aainfo，顯示顯示器，鍵盤， 鼠標 使用的aalib驅動程序
aainfo displays information about what drivers aalib will use for the display, keyboard, and mouse, and what parameters, such as screen size those drivers will use
8. aalib-config ， 為aalib提供配置信息.
Usage: aalib-config [--prefix[=DIR]] [--exec-prefix[=DIR]] [--version] [--libs] [--cflags]
9. aasavefont 保存一中字體到文件
10.aatest 顯示 測試 aalib 能力
11. aaxine 將mp3，mepg格式文件輸出為ascii 格式
--------------------------------------------------------
終於來了個有用的命令
12. ab ，apache 的一個hhtp 壓力測試命令
-c 並發數， -n請求次數
[root@jjy ~/q/data/tmp_data]# ab -c 3 -n10 http://www.baidu.com/

15. accept 接受/拒絕作業發送到目的地,一版作用於打印機吧
16. accountwizard 賬戶管理工具
17. accton 打開或關閉進程統計信息
#touch /var/log/pacct
然後運行：
# accton /var/log/pacct
一旦accton被激活，就可以使用lastcomm命令監測系統中任何時候執行的命令。若要關閉統計，可以使用不帶任何參數的accton命令：
# accton
