|
|
- `MY_PI` which contains the number `3.142`.
|

### Hints
|
||
|
|
|
||
|
|
Creating variables:
|
||
|
|
|
||
|
|
Variables can be created either at the shell or in shell-scripts. Any variable created within a shell script is lost when the script stops executing. A variable created at the prompt, however, will remain in existence until the shell is terminated. The syntax for creating a variable is :
|
||
|
|
|
||
|
|
`<variable name>=<value>`
