　　$find
　　其中指定从哪个目录开始搜索。指定搜索条件。表C找到文件怎么处理。一般来_要用-print动作Q显C?整个文g路径和名U。如果没有这个动作，则find命oq行所要搜索而不昄l果Q等于白费劲?
　　例如Q要搜烦pȝ上所有名UCؓye的文Ӟ可用如下命oQ?
　　$find / -name ye -print
　　q样可以显C出pȝ上所有名UCؓye的文件?
　　
　　tar
　　tar最初用于徏立磁带备份系l，目前q泛用于建立文g发布案。可用如下方法徏立tar案Q?
　　$tar cvf
　　例如Q如果要当前目录中所有文件存档到ye.tar中，可用如下命oQ?
　　$tar cvf ye.tar *.*
　　要浏览案内容，c选项变成t。如果要览ye.tar档案中的内容Q可用如下命令：
　　$tar tvf ye.tar
　　要取出案内的内容，c选项变成x。如果要ye.tar案中的内容取到当前目录中，可用如下命oQ?
　　$tar xvf ye.tar
　　
　　gzip
　　gzip命o用于压羃文g?例如Q如果要ye.txt文g压羃Q可用如下命令：
　　$gzip ye.txt
　　q样可以压~文件ƈ在文件名后面加上gz扩展名，变成文gye.txt.gz?
　　解压~文件可用gzip -d命o实现Q?
　　$gzip -d ye.txt.gz
　　q样可以解压羃文gq删除gz扩展名。除此之外还可以用gunzip命o来解 压羃文gQ效果跟用gzip -d命o一栗?
　　旧版的tar命o不压~案，可用gzip压羃。例如：
　　$tar cvf ye.tar *.txt
　　$gzip ye.tar
　　则可建立压羃档案ye.tar.gz?
　　新版的tar可以直接讉K和徏立gzip压羃的tar案Q只要在tar命o中加上z 选项可以了。例如：
　　$tar czvf ye.tar *.txt
　　生成压羃案ye.tar.gzQ?
　　$tar tzvf ye.tar *.txt
　　昄压羃案ye.tar.gz的内容，?
　　$tar xzvf ye.tar *.txt
　　取出压羃档案ye.tar.gz的内宏V?
　　
　　mkdir
　　q个命o很简单，跟dos的md命o用法几乎一P用于建立目录?
　　
　　cp
　　cp命o用于复制文g或目录?
　　cp命o可以一ơ复制多个文Ӟ例如Q?
　　$cp *.txt *.doc *.bak /home
　　当前目录中扩展名ؓtxt、doc和bak的文件全部复制到/home目录中?
　　如果要复制整个目录及其所有子目录Q可以用cp -R命o?
　　
　　rm
　　rm命o用于删除文g或目录?
　　rm命o会强制删除文Ӟ如果惌在删除时提示认Q可用rm -i命o?
　　如果要删除目录，可用rm -r命o。rm -r命o在删除目录时Q每删除一个文件或目录都会昄提示Q如果目录太大，响应每个提示是不现实的。这时可以用 rm -rf命o来强制删除目录，q样即用了-i标志也当无效处理?
　　
　　mv
　　mv命o用于Ud文g和更名文件。例如：
　　$mv ye.txt /home
　　当前目录下的ye.txt文gUd?home目录下，
　　$mv ye.txt ye1.txt
　　ye.txt文g改名为ye1.txt?
　　cM于跟cp命oQmv命o也可以一ơ移动多个文Ӟ在此不再赘叙?
　　
　　reboot
　　重启命oQ不必多说?
　　
　　halt
　　x命oQ不必多说?

/sbin/ ?许多pȝ命oQ例?shutdownQ的贮存位置。目?/usr/sbin 中也包括了许多系l命令?

/root/ ?根用P用户Q的ȝ录?

/mnt/ ?该目录中通常包括pȝ引导后被挂蝲?span class="t_tag" onclick="tagshow(event)" href="tag.php?name=%CE%C4%BC%FE">文gpȝ的挂载点。譬如，默认的光盘挂载点?/mnt/cdrom/.

/boot/ ?包括内核和其它系l启动期间用的文g?

/lost+found/ ??fsck 用来攄零散文gQ没有名U的文gQ?

/lib/ ?包含许多?/bin/ ?/sbin/ 中的E序使用的库文g。目?/usr/lib/ 中含有更多用于用?span class="t_tag" onclick="tagshow(event)" href="tag.php?name=%B3%CC%D0%F2">E序的库文g?

/dev/ ?贮存讑֤文g?
