<p>直接在shell里设定的命令别名，在终端关闭或者系统重新启动后都会失效，如何才能永久有效呢？</p>

<p>使用编辑器打开<code>~/.bashrc</code>，在文件中加入别名设置，如：alias rm='rm -i'，保存后执行<code>source ~/.bashrc</code>，这样就可以永久保存命令的别名了。</p>

<p>因为修改的是当前用户目录下的<code>~/.bashrc</code>文件，所以这样的方式只对当前用户有用。如果要对所有用户都有效，修改<code>/etc/bashrc</code>文件就可以了。</p>

<p>Q：如果我要显示一到多个别名，但不知道其中是否有未定义的该怎么办？</p>
|
||||
<p>A：正常执行就是了，alias不会因为有一个未定义的别名就结束对剩余参数的执行。</p>
|
||||
<p>Q：如果我这么定义<code>alias cd='ls' ls='cd'</code>，会有什么后果？</p>
|
||||
<p>A：运行cd依然会切换目录，运行ls依然会列出文件夹的内容；不要这样定义。</p>

<p><strong>apropos命令</strong> 在一些特定的包含系统命令的简短描述的数据库文件里查找关键字，然后把结果送到标准输出。 </p>
|
||||
<p>如果你不知道完成某个特定任务所需要命令的名称，可以使用一个关键字通过Linux apropos实用程序来搜索它。该实用程序可以搜索关键字并且显示所有包含匹配项的man页面的简短描述。另外，使用man实用程序和-k（关键字）选项，可以得到和用Linux apropos实用程序相同的结果（实际上是相同的命令）。</p>

<p>使用apt-get命令的第一步就是引入必需的软件库，Debian的软件库也就是所有Debian软件包的集合，它们存在互联网上的一些公共站点上。把它们的地址加入，apt-get就能搜索到我们想要的软件。/etc/apt/sources.list是存放这些地址列表的配置文件，其格式如下：</p>

<p><strong>aptitude命令</strong> 与apt-get命令一样，都是Debian Linux及其衍生系统中功能极其强大的包管理工具。与apt-get不同的是，aptitude在处理依赖问题上更佳一些。举例来说，aptitude在删除一个包时，会同时删除本身所依赖的包。这样，系统中不会残留无用的包，整个系统更为干净。它通过文本操作菜单和命令两种方式管理软件包。</p>

<p><strong>arp 命令</strong> 是 Address Resolution Protocol，地址解析协议，是通过解析网络层地址来找寻数据链路层地址的一个网络协议包中极其重要的网络传输协议。而该命令可以显示和修改 arp 协议解析表中的缓冲数据。</p>
|
||||
<p>这个核心协议模块实现RFC826中定义的 Address Resolution Protocol [译注：即TCP/IP的第三层到第一层的地址转换协议]，用于在直接相连的网络中换第二层硬件地址和 Ipv4 协议地址之间的转换。 用户除非想对其进行配置，否则一般不会直接操作这个模块。</p>
|
||||
<p>实际上，它提供对核心中其它协议的服务。</p>

<p>ARP 模块维护一个硬件地址到协议地址映射的缓存。这个缓存有大小限制，所以不常用的和旧的记录（Entry）将被垃圾收集器清除（garbage-collected），垃圾收集器永远不能删除标为永久的记录。我们可以使用ioctls直接操纵缓冲， 并且其性状可以用下面定义的 sysctl 调节。</p>
|
||||
<p>如果在限定的时间（见下面的sysctl）内，一条现存映射没有肯定反馈时， 则认为相邻层的缓存记录失效。 为了再次向目标发送数据，ARP将首先试着询问本地arp进程 app_solicit 次，获取更新了的 MAC（介质访问控制）地址。 如果失败，并且旧的MAC地址是已知的，则发送 ucast_solicit 次的 unicast probe。如果仍然失败，则将向网络广播一个新的ARP请求,此时要 有待发送数据的队列</p>
|
||||
<p>如果 Linux 接到一个地址请求，而且该地址指向 Linux 转发的地址，并且接收接口打开了代理 arp 时，Linux 将自动添加一条非永久的代理 arp 记录；如果存在拒绝到目标的路由，则不添加代理 arp 记录。</p>

<p><strong>at命令</strong> 用于在指定时间执行命令。at允许使用一套相当复杂的指定时间的方法。它能够接受在当天的hh:mm（小时:分钟）式的时间指定。假如该时间已过去，那么就放在第二天执行。当然也能够使用midnight（深夜），noon（中午），teatime（饮茶时间，一般是下午4点）等比较模糊的 词语来指定时间。用户还能够采用12小时计时制，即在时间后面加上AM（上午）或PM（下午）来说明是上午还是下午。 也能够指定命令执行的具体日期，指定格式为month day（月 日）或mm/dd/yy（月/日/年）或dd.mm.yy（日.月.年）。指定的日期必须跟在指定时间的后面。</p>
|
||||
<p>上面介绍的都是绝对计时法，其实还能够使用相对计时法，这对于安排不久就要执行的命令是很有好处的。指定格式为：<code>now + count time-units</code>，now就是当前时间，time-units是时间单位，这里能够是minutes（分钟）、hours（小时）、days（天）、weeks（星期）。count是时间的数量，究竟是几天，还是几小时，等等。 更有一种计时方法就是直接使用today（今天）、tomorrow（明天）来指定完成命令的时间。</p>

<p><strong>awk</strong> 是一种编程语言，用于在linux/unix下对文本和数据进行处理。数据可以来自标准输入(stdin)、一个或多个文件，或其它命令的输出。它支持用户自定义函数和动态正则表达式等先进功能，是linux/unix下的一个强大编程工具。它在命令行中使用，但更多是作为脚本来使用。awk有很多内建的功能，比如数组、函数等，这是它和C语言的相同之处，灵活性是awk最大的优势。</p>

<p>作为一种程序设计语言所应具有的特点之一，awk支持多种运算，这些运算与C语言提供的基本相同。awk还提供了一系列内置的运算函数（如log、sqr、cos、sin等）和一些用于对字符串进行操作（运算）的函数（如length、substr等等）。这些函数的引用大大的提高了awk的运算功能。作为对条件转移指令的一部分，关系判断是每种程序设计语言都具备的功能，awk也不例外，awk中允许进行多种测试，作为样式匹配，还提供了模式匹配表达式~（匹配）和!~（不匹配）。作为对测试的一种扩充，awk也支持用逻辑运算符。</p>

<p>在linux awk的while、do-while和for语句中允许使用break,continue语句来控制流程走向，也允许使用exit这样的语句来退出。break中断当前正在执行的循环并跳到循环外执行下一条语句。if 是流程选择用法。awk中，流程控制语句，语法结构，与c语言类型。有了这些语句，其实很多shell程序都可以交给awk，而且性能是非常快的。下面是各个语句用法。</p>

<p>awk的多维数组在本质上是一维数组，更确切一点，awk在存储上并不支持多维数组。awk提供了逻辑上模拟二维数组的访问方式。例如，<code>array[2,4]=1</code>这样的访问是允许的。awk使用一个特殊的字符串<code>SUBSEP(<28>34)</code>作为分割字段，在上面的例子中，关联数组array存储的键值实际上是2<EFBFBD>344。</p>
|
||||
<p>类似一维数组的成员测试，多维数组可以使用<code>if ( (i,j) in array)</code>这样的语法，但是下标必须放置在圆括号中。类似一维数组的循环访问，多维数组使用<code>for ( item in array )</code>这样的语法遍历数组。与一维数组不同的是，多维数组必须使用<code>split()</code>函数来访问单独的下标分量。</p>

<p><strong>badblock命令</strong> 用于查找磁盘中损坏的区块。 硬盘是一个损耗设备，当使用一段时间后可能会出现坏道等物理故障。电脑硬盘出现坏道后，如果不及时更换或进行技术处理，坏道就会越来越多，并会造成频繁死机和数据丢失。最好的处理方式是更换磁盘，但在临时的情况下，应及时屏蔽坏道部分的扇区，不要触动它们。badblocks就是一个很好的检查坏道位置的工具。</p>

<p>这次花费的时间比较短，硬盘在指定的情况下在很短的时间就产生“嘎嘎嘎嘎”的响声。由于检查条件的不同，其输出的结果也不完全是相同的。重复几次同样的操作，因条件多少都有些不同，所以结果也有所不同。进行多次操作后，直到产生最后的hda-badblock-list.final文件。</p>

<p><strong>bunzip2命令</strong> 解压缩由bzip2指令创建的”.bz2"压缩包。对文件进行压缩与解压缩。此命令类似于“gzip/gunzip”命令，只能对文件进行压缩。对于目录只能压缩目录下的所有文件，压缩完成后，在目录下生成以“.bz2”为后缀的压缩包。bunzip2其实是bzip2的符号链接，即软链接，因此压缩解压都可以通过bzip2实现。</p>

<p><strong>bzip2命令</strong> 用于创建和管理（包括解压缩）“.bz2”格式的压缩包。</p>
|
||||
<p>bzip2 采用 Burrows-Wheeler 块排序文本压缩算法和 Huffman 编码方式压缩文件。 压缩率一般比基于 LZ77/LZ78 的压缩软件好得多，其性能接近 PPM 族统计类压缩软件。</p>
|
||||
<p>命令行参数有意设计为非常接近 GNU gzip 的形式，但也不完全相同。</p>

@ -75,14 +71,10 @@ anyothername 解压成 anyothername.out
|
|||
<p>在压缩时，如果不提供文件名，bzip2 将从标准输入读取数据，压缩结果写往标准输出。</p>
|
||||
<p>bzip2 采用 32 位 CRC 校验码作自我检查，以确认解压后的文件与原始文件相同。 这可用于检测压缩文件是否损坏，并防止 bzip2 中未知的缺陷（运气好的话这种可能性非常小）。 数据损坏而未检测到的几率非常之小， 对于每个被处理的文件大约是四十亿分之一。 检查是在解压缩时进行的，因此它只能说明某个地方出问题了。 它能帮助恢复原始未压缩的数据。可以用 bzip2recover 来尝试从损坏的文件中恢复数据。</p>
|
||||
<p>返回值：正常退出返回 0， 出现环境问题返回 1 （文件未找到，非法的选项，I/O错误等）， 返回 2 表明压缩文件损坏，出现导致 bzip2 紧急退出的内部一致性错误（例如缺陷）时返回 3。</p>

<p><strong>bzip2recover命令</strong> 可用于恢复被破坏的“.bz2”压缩包中的文件。</p>
|
||||
<p>bzip2是以区块的方式来压缩文件，每个区块视为独立的单位。因此，当某一区块损坏时，便可利用bzip2recover，试着将文件中的区块隔开来，以便解压缩正常的区块。通常只适用在压缩文件很大的情况。</p>

<p><strong>chcon命令</strong> 是修改对象（文件）的安全上下文，比如：用户、角色、类型、安全级别。也就是将每个文件的安全环境变更至指定环境。使用<code>--reference</code>选项时，把指定文件的安全环境设置为与参考文件相同。chcon命令位于<code>/usr/bin/chcon</code>。</p>

<p><strong>chgrp命令</strong> 用来改变文件或目录所属的用户组。该命令用来改变指定文件所属的用户组。其中，组名可以是用户组的id，也可以是用户组的组名。文件名可以 是由空格分开的要改变属组的文件列表，也可以是由通配符描述的文件集合。如果用户不是该文件的文件主或超级用户(root)，则不能改变该文件的组。</p>
|
||||
<p>在UNIX系统家族里，文件或目录权限的掌控以拥有者及所属群组来管理。您可以使用chgrp指令去变更文件与目录的所属群组，设置方式采用群组名称或群组识别码皆可。</p>

<p><strong>chroot命令</strong> 用来在指定的根目录下运行指令。chroot，即 change root directory （更改 root 目录）。在 linux 系统中，系统默认的目录结构都是以<code>/</code>，即是以根 (root) 开始的。而在使用 chroot 之后，系统的目录结构将以指定的位置作为<code>/</code>位置。</p>
|
||||
<p>在经过 chroot 命令之后，系统读取到的目录和文件将不在是旧系统根下的而是新根下（即被指定的新的位置）的目录结构和文件，因此它带来的好处大致有以下3个：</p>

<p><strong>增加了系统的安全性，限制了用户的权力：</strong></p>

<p>使用 chroot 后，系统读取的是新根下的目录和文件，这是一个与原系统根下文件不相关的目录结构。在这个新的环境中，可以用来测试软件的静态编译以及一些与系统不相关的独立开发。</p>

<p><strong>切换系统的根目录位置，引导 Linux 系统启动以及急救系统等：</strong></p>
|
||||
<p>chroot 的作用就是切换系统的根位置，而这个作用最为明显的是在系统初始引导磁盘的处理过程中使用，从初始 RAM 磁盘 (initrd) 切换系统的根位置并执行真正的 init。另外，当系统出现一些问题时，我们也可以使用 chroot 来切换到一个临时的系统。</p>

<p><strong>cksum命令</strong> 是检查文件的CRC是否正确，确保文件从一个系统传输到另一个系统的过程中不被损坏。这种方法要求校验和在源系统中被计算出来，在目的系统中又被计算一次，两个数字进行比较，如果校验和相等，则该文件被认为是正确传输了。</p>
|
||||
<p>注意：CRC是指一种排错检查方法，即循环冗余校验法。</p>
|
||||
<p>指定文件交由cksum命令进行校验后，会返回校验结果供用户核对文件是否正确无误。若不指定任何文件名称或是所给予的文件名为"-"，则cksum命令会从标准输入设备中读取数据。</p>

<p><strong>cmp命令</strong> 用来比较两个文件是否有差异。当相互比较的两个文件完全一样时，则该指令不会显示任何信息。若发现有差异，预设会标示出第一个不通之处的字符和列数编号。若不指定任何文件名称或是所给予的文件名为“-”，则cmp指令会从标准输入设备读取数据。</p>

<p><strong>col命令</strong> 是一个标准输入文本过滤器，它从标注输入设备读取文本内容，并把内容显示到标注输出设备。在许多UNIX说明文件里，都有RLF控制字符。当我们运用shell特殊字符<code>></code>和<code>>></code>，把说明文件的内容输出成纯文本文件时，控制字符会变成乱码，col命令则能有效滤除这些控制字符。</p>

<p><strong>compress命令</strong> 使用“Lempress-Ziv”编码压缩数据文件。compress是个历史悠久的压缩程序，文件经它压缩后，其名称后面会多出".Z"的扩展名。当要解压缩时，可执行uncompress指令。事实上uncompress是指向compress的符号连接，因此不论是压缩或解压缩，都可通过compress指令单独完成。</p>

<p>下面的第一行中是 cp 命令和具体的参数（-r 是“递归”， -u 是“更新”，-v 是“详细”）。接下来的三行显示被复制文件的信息，最后一行显示命令行提示符。这样，只拷贝新的文件到我的存储设备上，我就使用 cp 的“更新”和“详细”选项。</p>
|
||||
<p>通常来说，参数 <code>-r</code> 也可用更详细的风格 <code>--recursive</code>。但是以简短的方式，也可以这么连用 <code>-ruv</code>。</p>

<p><strong>csplit命令</strong> 用于将一个大文件分割成小的碎片，并且将分割后的每个碎片保存成一个文件。碎片文件的命名类似“xx00”，“xx01”。csplit命令是split的一个变体，split只能够根据文件大小或行数来分割，但csplit能够根据文件本身特点来分割文件。</p>

<p><strong>curl命令</strong> 是一个利用URL规则在命令行下工作的文件传输工具。它支持文件的上传和下载，所以是综合传输工具，但按传统，习惯称curl为下载工具。作为一款强力工具，curl支持包括HTTP、HTTPS、ftp等众多协议，还支持POST、cookies、认证、从指定偏移处下载部分文件、用户代理字符串、限速、文件大小、进度条等特征。做网页处理流程和数据检索自动化，curl可以祝一臂之力。</p>

<p>说明：该命令有两项功能，其一是用来显示文件的内容，它依次读取由参数 file 所指 明的文件，将它们的内容输出到标准输出上；其二是连接两个或多个文件，如<code>cut fl f2 > f3</code>将把文件 fl 和 f2 的内容合并起来，然后通过输出重定向符“>”的作用，将它们放入文件 f3 中。</p>
|
||||
<p>当文件较大时，文本在屏幕上迅速闪过（滚屏），用户往往看不清所显示的内容。因此，一般用 more 等命令分屏显示。为了控制滚屏，可以按 Ctrl+S 键，停止滚屏；按 Ctrl+Q 键可以恢复滚屏。按 Ctrl+C（中断）键可以终止该命令的执行，并且返回 Shell 提示符状态。</p>

<p><strong>dd命令</strong> 用于复制文件并对原文件的内容进行转换和格式化处理。dd命令功能很强大的，对于一些比较底层的问题，使用dd命令往往可以得到出人意料的效果。用的比较多的还是用dd来备份裸设备。但是不推荐，如果需要备份oracle裸设备，可以使用rman备份，或使用第三方软件备份，使用dd的话，管理起来不太方便。</p>
|
||||
<p>建议在有需要的时候使用dd 对物理磁盘操作，如果是文件系统的话还是使用tar backup cpio等其他命令更加方便。另外，使用dd对磁盘操作时，最好使用块设备文件。</p>

<p><strong>diff命令</strong> 在最简单的情况下，比较给定的两个文件的不同。如果使用“-”代替“文件”参数，则要比较的内容将来自标准输入。diff命令是以逐行的方式，比较文本文件的异同处。如果该命令指定进行目录的比较，则将会比较该目录中具有相同文件名的文件，而不会对其子目录文件进行任何比较操作。</p>

<p><strong>dirname命令</strong> 去除文件名中的非目录部分，仅显示与目录有关的内容。dirname命令读取指定路径名保留最后一个<code>/</code>及其后面的字符，删除其他部分，并写结果到标准输出。如果最后一个<code>/</code>后无字符，dirname 命令使用倒数第二个<code>/</code>，并忽略其后的所有字符。dirname 和 basename 通常在 shell 内部命令替换使用，以指定一个与指定输入文件名略有差异的输出文件名。</p>
