The argument enter on the command line is a first and last name ( for example: "John Smith").
If the argument is a validly formatted name, you display The "name enter" is valid to standard out.
If the argument is not a validly formated name, you display The "name enter" is not valid to standard out
For Example,
$ valid_name "John Smith" John Smith is valid =========
$ valid_name "John smith" John smith is not valid =========
$ valid_name "John" John is not valid
==========
$ valid_name "jOhn Smith" jOhn Smith is not valid ===========
$ valid_name "John sMith" John sMith is not valid
This is what I have so far:
I need to use grep or sed somehow right? I cannot figure this out for the life of me.
Please help.

How to check the user input to be valid using shell script?
The valid input is in the format like as follows.

round
ROUND(3) 1 ROUND(3)round - Rounds a floatSYNOPSIS
float round (float $val, [int $precision], [int $mode = PHP_ROUND_HALF_UP])
DESCRIPTION
Returns the rounded value of $val to specified $precision (number of digits after the decimal point). $precision can also be negative or
zero (default).
Note
PHP doesn't handle strings like "12,300.2" correctly by default. See converting from strings.
PARAMETERS
o $val
- The value to round
o $precision
- The optional number of decimal digits to round to.
o $mode
- Use one of the following constants to specify the mode in which rounding occurs.
+--------------------+---------------------------------------------------+
| Constant | |
| | |
| | Description |
| | |
+--------------------+---------------------------------------------------+
| | |
| PHP_ROUND_HALF_UP | |
| | |
| | Round $val up to $precision decimal places away |
| | from zero, when it is half way there. Making 1.5 |
| | into 2 and -1.5 into -2. |
| | |
| | |
|PHP_ROUND_HALF_DOWN | |
| | |
| | Round $val down to $precision decimal places |
| | towards zero, when it is half way there. Making |
| | 1.5 into 1 and -1.5 into -1. |
| | |
| | |
|PHP_ROUND_HALF_EVEN | |
| | |
| | Round $val to $precision decimal places towards |
| | the next even value. |
| | |
| | |
|PHP_ROUND_HALF_ODD | |
| | |
| | Round $val to $precision decimal places towards |
| | the next odd value. |
