Definitions
- CLI: Command Line interface
$ pwd: path of working directory - flags: preceded by -
- arguments : other options of the command or canbe what the command is going to modify
- there can be zero or more flags and arguments
Basic Commands
- 'jeff$ clear'
-'jeff$ ls'; 'jeff$ ls -a'; 'jeff$ ls -al'
-'jeff$ cd' :=change directory
'jeff$ cd' without arguments or flags would takes you to your home directory - 'jeff$cd ..' change to one level above your current directory.
-'jeff$ mkdir' =make directory
eg. 'jeff$ mkdir Documents(this is an argument )' - 'jeff$ cp test_file Documents'
- '$ touch test_file' =create a new file named as 'test_file'
- '$ cp test_file Documents' =copy the 'test_file' to 'Documents'
note: the first argument is the name of the files you want to copy; the second argument is the path you choose to copy. Pay attention to your path; the right spelling is ' E:\test_cld\music', The '' has to be doubled as '\'
-'$ cp -r ' can be used for copying the contents of directories. r means recursive （递归的，循环的）
eg.'$ cp -r Documents More_docs' copies the contents of 'Documents' into 'More_docs' - '$ rm' = remove =delete
eg.'$rm test_file' - '$rm -r '= delete entire directions and their contents by using the -r flag.
note :be careful when you do this. - '$ mv new_file Documents' =move a file to another directory
note: '$mv filename1 filename2' can also be used for changing the name of a file when the second argument is a filename rather than a path or directory.
-'$ echo Hello world' =to print out 'hello world'
-'$ date'
Create a local copy
- Initialize a local git repository in the directory need copied
$ git init
- Point the local repository at the remote repository you just created on the GitHub Server.
$ git remote add origin https://github.com/yourusernamehere/repo-name.git
- make a local copy of the repo on your computer from the github server by :
$ git clone https://github.com/yourusernamehere/repo-name.git
note : this will clone the repository into your current directory.
