Very nice, works well. Can you do me a huge favor and break down the sed command you used here and why it works the way it does... I am still trying to figure out how to properly use it and I learn by examples better than reading hypothetical explanations.
I set my path environment variable in c shell, using the
syntax below
setenv PATH "${PATH}:/usr/local:/usr/local/bin"
and placed this in $HOME/.login
$HOME/.cshrc
and /etc/.login
/etc/.cshrc
but when I issued echo $PATH or set command
the output does not reflect changes made to... (5 Replies)

I've noted that in order to use commands like ifconfig, I have to prefix the commands with the directory.
/etc/profile shows that the paths should be part of the PATH environment variable; any idea where the bug is?

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. |
