    google.com => argument
ping directdevops.blog

ping -n 10 directdevops.blog

• Any application has two types of arguments
  • positional arguments
  • keyword arguments

position arguments

• Example

cp <src> <dest>

* In the above case passing arguments was necessary & along with that maintaining position was also criticial
* Generally position arguments are passed directly

Keyword arguments

• Example:

ping -n 1 google.com

• Here -n stands for number of echo requests and 1 represents value

-n => name of the argument
1 => value of the argument

• Generally in most of linux commands. Named arguments will be in the following form

-<singlecharacter>
--<word>

cp --recursive
cp -r
