I have a script that takes an option for server pools to run the script against. The option is given as a comma separated list (ie, -p 201,204,301).
I'm using eval and brace expansion to get those pool numbers into an array. It works fine unless only 1 pool number is given. Here's the code:

Hello,
is there a kind soul who can answer me, does the SH support double substitution known as indirect expansion similar to BASH? The syntax for bash is ${!var}.
For instance in bash I can write something like this:
VAR="value"
REF_VAR="VAR"
echo ${!REF_VAR}
and get the "value"... (1 Reply)
This is what I have in my directory.

dirname
DIRNAME(3) 1 DIRNAME(3)dirname - Returns parent directory's pathSYNOPSIS
string dirname (string $path)
DESCRIPTION
Given a string containing the path of a file or directory, this function will return the parent directory's path.
PARAMETERS
o $path
- A path. On Windows, both slash ( /) and backslash ( ) are used as directory separator character. In other environments, it is
the forward slash ( /).
RETURN VALUES
Returns the path of the parent directory. If there are no slashes in $path, a dot (' .') is returned, indicating the current directory.
Otherwise, the returned string is $path with any trailing /component removed.
CHANGELOG
+--------+-------------------------------+
|Version | |
| | |
| | Description |
| | |
+--------+-------------------------------+
| 5.0.0 | |
| | |
| | dirname(3) is now binary safe |
| | |
+--------+-------------------------------+
EXAMPLES
Example #1
dirname(3) example
<?php
echo "1) " . dirname("/etc/passwd") . PHP_EOL; // 1) /etc
echo "2) " . dirname("/etc/") . PHP_EOL; // 2) / (or on Windows)
echo "3) " . dirname("."); // 3) .
?>
NOTES
Note
dirname(3) operates naively on the input string, and is not aware of the actual filesystem, or path components such as " ..".
Note
dirname(3) is locale aware, so for it to see the correct directory name with multibyte character paths, the matching locale must be
set using the setlocale(3) function.
Note
Since PHP 4.3.0, you will often get a slash or a dot back from dirname(3) in situations where the older functionality would have
given you the empty string.
Check the following change example:
<?php
//before PHP 4.3.0
dirname('c:/'); // returned '.'
//after PHP 4.3.0
dirname('c:/x'); // returns 'c:'
dirname('c:/Temp/x'); // returns 'c:/Temp'
dirname('/x'); // returns ''
?>
