1. a2p 将awk 脚本转化为perl 脚本命令

转化后的结果并不一定可靠，需要人工干预.

 

[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];
}

2. a2ping 图片、文档格式转化命令

 

[root@jjy ~/q/data/tmp_data]# a2ping --bboxfrom=compute-gs /notSolidHd/learing_document/shell12.pdf xx.eps

接受输入格式： PS (PostScript), EPS, PDF, PNG, JPEG, TIFF, PNM, BMP, GIF, LBM, XPM, PCX, TGA.

接受输出格式: EPS, PCL5, PDF, PDF1, PBM, PGM, PPM, PS, markedEPS, markedPS, PNG, XWD, BMP, TIFF, JPEG, GIF, XPM.

依赖于 sam2p 与 gs 命令

3. a2ps设置打印如何在打印页上显示文本或图形。

4.a2x 将asciidoc 文档转化为其它格式

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.

转化为pdf格式
[root@jjy ~/q/data/tmp_data]# a2x -fpdf minimal-book.txt

5. a2x.py 与a2x一样， 只不过为python版本

首先介绍一下aalib

 

aalib 是把所有的图形转换成ascii码的库文件.

AAlib is a software library which allows applications to automatically convert still and moving images into ASCII art.

6. aafire , 在terminal中显示一团火焰

7. aainfo，显示显示器，键盘， 鼠标 使用的aalib驱动程序

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 ， 为aalib提供配置信息.

Usage: aalib-config [--prefix[=DIR]] [--exec-prefix[=DIR]] [--version] [--libs] [--cflags]

9. aasavefont 保存一中字体到文件

10.aatest 显示 测试 aalib 能力

11. aaxine 将mp3，mepg格式文件输出为ascii 格式

--------------------------------------------------------

终于来了个有用的命令

12. ab ，apache 的一个hhtp 压力测试命令

-c 并发数， -n请求次数

15. accept 接受/拒绝作业发送到目的地,一版作用于打印机吧

16. accountwizard 账户管理工具

17. accton 打开或关闭进程统计信息

 

#touch /var/log/pacct

然后运行：

# accton /var/log/pacct

一旦accton被激活，就可以使用lastcomm命令监测系统中任何时候执行的命令。若要关闭统计，可以使用不带任何参数的accton命令：

# accton
