来源:互联网 发布:软件行业人均产值 编辑:程序博客网 时间:2024/05/17 06:49
1.通过远程工具登陆到linux后,所在的位置是当前登录用户的家目录(home directory)。
2.家目录的符号用~表示。
3.linux的文件系统是一个树结构。
  linux文件系统的树根成为根目录,使用符号"/"表示。
  linux文件系统中使用符号".."表示上级目录。
  linux文件系统中使用符号"."表示当前目录。
  linux文件系统中,如果文件使用“.”开头,就表示隐藏文件
  linux的路径表示方式有两种,一种是绝对路径(以”/“开头的路径),一种是相对路径
4.命令cd(
change directory):跳转到其他目录
5.命令ls(list(列出目录内容)):查看目录下包含什么东西

      ls  -l:显示详细信息

(参数含义: -1                         list one file per line)

      ls  -a:显示隐藏文件

  (参数含义: -a, --all                  do not ignore entries starting with .)

6.命令pwd(print work directory 打印当前目录 显示出当前工作目录的绝对路径):显示当前所处位置的
7.命令clear:清屏
8.命令mkdir(Make Directory(创建目录)):创建文件夹

 mkdir -p  :递归创建上级文件夹

(比如创建: mkdir test1/test2/test3 ,test1和test2和test3都没有创建,就会递归创建这三个文件夹)

(参数含义: -p, --parents     no error if existing, make parent directories as needed)

9.命令touch:创建空白文件
10.命令more:查看文件内容
11.命令rm(Remove(删除目录或文件)):删除文件
   命令rmdir(Remove Directory(删除目录)):删除文件夹

   命令rm -rf:删除文件(夹),不论层级多深,一概删除,并且不给出提示

这里的参数: -r, -R, --recursive   remove directories and their contents recursively;

                             -f, --force           ignore nonexistent files, never prompt;

12.命令cp(copy):复制文件,还有一个功能是创建新文件
13.命令mv(move): 移动文件,还有个功能是重命名
*********************************
VI操作:
(1)当使用命令vi f1回车时,进入了vi编辑器内,处于只读状态(只能看不能写);
(2)按字母”i“(insert)或者”a“(append)就可以进入编辑状态;
(3)按键盘上的”Esc“键,再按Shift+:,进入命令状态
如果输入命令wq,意味着保存退出;
如果输入命令q!,意味着不保存退出;
*********************************
linux的权限使用9位字符表示,rwx rwx rwx
这里面r表示读权限,w表示写权限,x表示执行权限,-表示没有权限


这9位字符,每3位一组,分为3组。
第一组表示创建者的权限;
第二组表示创建者所在组的权限;
第三组表示其他人的权限;


权限还可以使用数字表示。rwx用数字表示为4+2+1=7。

新创建文件的默认权限是644;新创建文件夹的默认权限是755.

确实,这是我新创建的文件和文件夹:


这里的d开头是文件夹,-开头是文件



命令chmod(Change mode):修改权限,三个组分别使用u(user)、g(group)、o(other)表示,赋权限使用“+”,去掉权限使用“-”。
           chmod u+x f1  //表示文件f1的创建者增加执行权限

  chmod o-r f1  //表示文件f1的其他人去掉读权限

数字更改权限事例:chmod 777 tewer  格式 :chmod  数字  文件或者文件夹  

chmod -R 777 test2 更改test2以及test2底下的所有文件夹和文件的权限 ,格式:chmod 参数  数字 文件夹(文件不会出错,照常执行)

参数含义: -R, --recursive         change files and directories recursively

recursive (
