## Positional Parameters

The shell assigns numbers called **'positional parameters**' to each command line argument that is entered. For example we use the **`cd`** (change directory to whichever directory you want to move to)  or **`cp`** (type the file you want to copy and where you want to copy that file to). \
The feature that makes this possible is "positional parameters"

**Example 1**: Lets create a bash script **`"positional_script.sh`**\
**`#!/bash/bin`**\
**`echo "My name is $1"`**\
**`echo "Hy home directory is $2"`**\
**`echo "My favourite colour is $3"`**\
\
**`chmod 744 positional_script.sh`**

**`$#> positional_script.sh John $HOME blue`**

**`My name is John`**\
**`My home directory is /home/john`**\
**`My favourite colour is blue`**

The **$1 $2 and $3** refer to the first, second and third command line arguments given to the script
