1.man
对于那些不确定其用法的命令(比如是:ls),我们可以首先使用man命令来了解
使用格式:man ls
可以使用空格键翻页,或者使用上、下箭头键上下翻页,要退出,则输入 q或 CTRL-Z。
2.find
如果您知道文件的名称、或者甚至名称的一部分,但不知道它所处的目录,可以使用find命令。比如你要找文件file,
命令格式:find / -name 'file'
3.ln
用于在文件之间建立链接
命令格式: ln [OPTION]... TARGET [LINK_NAME]
常用的[OPTION]:-s, --symbolic make symbolic links instead of hard links
执行这个命令之后,[LINK_NAME]-->TARGET,二者建立了链接关系,所有指向[LINK_NAME]的动作都会重新指向TARGET.
4.tar
tar是个归档命令,通过使用适当的选项可以压缩/解压缩文件.常见的如:
解压缩.gz文件: tar -zxf ZipFileName.tar.gz
解压缩.bz2文件: tar -jxf ZipFileName.tar.bz2
5.yum
