Hello Community!
Let's say that we have some script which counts its arguments number: arguments_count.sh:
and some test script: test.sh:
Output after execute test.sh is:

Hi,
how can I join given arguments (not starting from the first one) to form one string, each argument separated by a space. For example, out of 5 given arguments, I'll like to start joining from the 3rd to the last. In python there exists something like ' '.join(sys.argv) and it starts joining... (5 Replies)
Hello, I was wondering if it were possible to call arguments passed to a script using a variable.
For example:
sh script.sh yes no good bad
x=$#
while
do
echo (last argument, then second last etc until first argument)
let x=($x-1)
done
should print out
bad
good
no (4 Replies)
The following bash script does not work because the java/groovy code always thinks there are four arguments even if there are only 1 or 2. As you can see from my hideous backslashes, I am using cygwin bash on windows.

Let's say I want to print the arguments $4 till $#, how can I do this?
$# contains the number of arguments
$@ contain all the arguments as string
What i need is something like

#do something with $i
convert $i ~/$output

Hi guys,
been scratching round the forums and my mountain of resources.
Maybe I havn't read deep enough
My question is not how sed edits a stream and outputs it to a file, rather something like this below:

Hi
The following code works when reading the arguments from the command line but fails when I try to read from a string. So this works

Hi. I have a piece of code that reads and parses command line options. I'd like to alter it slightly to read from a string (that's set elsewhere in the script) rather than directly from the command line (arg). Can somebody show me how to do this? Many thanks.
My code is as follows:

func_get_arg
FUNC_GET_ARG(3) 1 FUNC_GET_ARG(3)func_get_arg - Return an item from the argument listSYNOPSIS
mixed func_get_arg (int $arg_num)
DESCRIPTION
Gets the specified argument from a user-defined function's argument list.
This function may be used in conjunction with func_get_args(3) and func_num_args(3) to allow user-defined functions to accept variable-
length argument lists.
PARAMETERS
o $arg_num
- The argument offset. Function arguments are counted starting from zero.
RETURN VALUES
Returns the specified argument, or FALSE on error.
CHANGELOG
+--------+---------------------------------------------------+
|Version | |
| | |
| | Description |
| | |
+--------+---------------------------------------------------+
| 5.3.0 | |
| | |
| | This function can now be used in parameter |
| | lists. |
| | |
| 5.3.0 | |
| | |
| | If this function is called from the outermost |
| | scope of a file which has been included by call- |
| | ing include(3) or require(3) from within a func- |
| | tion in the calling file, it now generates a |
| | warning and returns FALSE. |
| | |
+--------+---------------------------------------------------+
ERRORS /EXCEPTIONS
Generates a warning if called from outside of a user-defined function, or if $arg_num is greater than the number of arguments actually
passed.
EXAMPLES
Example #1
func_get_arg(3) example
<?php
function foo()
{
$numargs = func_num_args();
echo "Number of arguments: $numargs
";
if ($numargs >= 2) {
echo "Second argument is: " . func_get_arg(1) . "
";
}
}
foo(1, 2, 3);
?>
The above example will output:
Number of arguments: 3
Second argument is: 2
Example #2
func_get_arg(3) example before and after PHP 5.3
test.php
<?php
function foo() {
include './fga.inc';
}
foo('First arg', 'Second arg');
?>
fga.inc
<?php
$arg = func_get_arg(1);
var_export($arg);
?>
Output previous to PHP 5.3:
Output in PHP 5.3 and later:
Warning: func_get_arg(): Called from the global scope - no function
context in /home/torben/Desktop/code/ml/fga.inc on line 3
false
Example #3
func_get_arg(3) example of byref and byval arguments
<?php
function byVal($arg) {
echo 'As passed : ', var_export(func_get_arg(0)), PHP_EOL;
$arg = 'baz';
echo 'After change : ', var_export(func_get_arg(0)), PHP_EOL;
}
function byRef(&$arg) {
echo 'As passed : ', var_export(func_get_arg(0)), PHP_EOL;
$arg = 'baz';
echo 'After change : ', var_export(func_get_arg(0)), PHP_EOL;
}
$arg = 'bar';
byVal($arg);
byRef($arg);
?>
The above example will output:
After change : 'bar' As passed : 'bar' After change : 'baz'
NOTES
Note
Because this function depends on the current scope to determine parameter details, it cannot be used as a function parameter in ver-
sions prior to 5.3.0. If this value must be passed, the results should be assigned to a variable, and that variable should be
passed.
Note
If the arguments are passed by reference, any changes to the arguments will be reflected in the values returned by this function.
Note
This function returns a copy of the passed arguments only, and does not account for default (non-passed) arguments.
