Me again! ...
I'm trying to build (on MacOS directly) a bash script that will help me verify a SHA1 digest (to verify downloads and so on and so forth).
So first off, here's my version of BASH under OSX:
And here's my version of Sierra (macOS):
and last but not least, here's my code:
Now, I know that $sha1 and $verifySha will not be the same for now... I need a sed in the middle to extract the sha signature.
But, aside from this minor problem that I will fix soon, I get the error:
Anyone has any idea why the openssl command does not work in a bash script? (Obviously, when I try to pass the command outside of the script, it works!).
I'm really new at this and wondering how I would go about adding code to my script to verify that all records loaded successfully? (I am loading a file into a table) i'm using the Korn shell.
I'm also having trouble verifying parts in the header as i do not really understand the header and... (3 Replies)

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. |
