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)

Hello.
I cannot write a command without using eval.
Any help is welcome

Hello All,
Could you please do help me here as I would like to perform parameter expansion in shell over a parameter expansion.

dirname
DIRNAME(3) BSD Library Functions Manual DIRNAME(3)NAME
dirname -- extract the directory part of a pathname
SYNOPSIS
#include <libgen.h>
char *
dirname(char *path);
DESCRIPTION
The dirname() function is the converse of basename(3); it returns a pointer to the parent directory of the pathname pointed to by path. Any
trailing '/' characters are not counted as part of the directory name. If path is a null pointer, the empty string, or contains no '/' char-
acters, dirname() returns a pointer to the string ".", signifying the current directory.
IMPLEMENTATION NOTES
The dirname() function returns a pointer to internal storage space allocated on the first call that will be overwritten by subsequent calls.
Other vendor implementations of dirname() may modify the contents of the string passed to dirname(); if portability is desired, this should
be taken into account when writing code which calls this function.
LEGACY SYNOPSIS
#include <libgen.h>
char *
dirname(const char *path);
In legacy mode, path will not be changed.
RETURN VALUES
On successful completion, dirname() returns a pointer to the parent directory of path.
If dirname() fails, a null pointer is returned and the global variable errno is set to indicate the error.
ERRORS
The following error codes may be set in errno:
[ENAMETOOLONG] The path component to be returned was larger than MAXPATHLEN.
SEE ALSO basename(1), dirname(1), basename(3), compat(5)STANDARDS
The dirname() function conforms to X/Open Portability Guide Issue 4, Version 2 (``XPG4.2'').
HISTORY
The dirname() function first appeared in OpenBSD 2.2 and FreeBSD 4.2.
