The problem in your approach in post #1 is bash's "indirection". man bash:
Quote:
Parameter Expansion
.
.
.
If the first character of parameter is an exclamation point (!), and parameter is not a nameref, it introduces a level of variable indirection.
That indirection works (in fact supplies an empty string) if x holds a string that could be a valid variable name but fails on * or . (which can't be part of a valid variable name).
@Scrutinizer: that's why the -f option doesn't take effect - no pathname expansion attempted.
May I question the use of indirection in your script? What do you want to achieve by using it? Your simplified script, purged from indirection, looks like
Code:
IFS=':'
for i in $LS_COLORS
do echo -e "\e[${i#*=}m${i%=*}\e[m"
done
[[0mrs[[m
[[01;34mdi[[m
[[01;36mln[[m
[[00mmh[[m
[[40;33mpi[[m
[[01;35mso[[m
[[01;35mdo[[m
[[40;33;01mbd[[m
[[40;33;01mcd[[m
[[40;31;01mor[[m
[[00mmi[[m
[[37;41msu[[m
[[30;43msg[[m
[[30;41mca[[m
[[30;42mtw[[m
[[34;42mow[[m
[[37;44mst[[m
[[01;32mex[[m
[[01;31m*.tar[[m
[[01;31m*.tgz[[m
[[01;31m*.arc[[m
and works perfectly well. I showed the console codes as the colours don't translate to html too well.
EDIT: Added the IFS defnition to enable the script's success...

ares_expand_string
ARES_EXPAND_NAME(3) Library Functions Manual ARES_EXPAND_NAME(3)NAME
ares_expand_string - Expand a length encoded string
SYNOPSIS
#include <ares.h>
int ares_expand_string(const unsigned char *encoded,
const unsigned char *abuf, int alen, unsigned char **s,
long *enclen)
DESCRIPTION
The ares_expand_string function converts a length encoded string to a NUL-terminated C string. The argument encoded gives the beginning of
the encoded string, and the arguments abuf and alen give the containing message buffer (necessary for the processing of indirection point-
ers within the encoded domain name). The result is placed in a NUL-terminated allocated buffer, a pointer to which is stored in the vari-
able pointed to by s. The length of the encoded string is stored in the variable pointed to by enclen so that the caller can advance past
the encoded string to read further data in the message.
RETURN VALUES
ares_expand_string can return any of the following values:
ARES_SUCCESS Expansion of the encoded string succeeded.
ARES_EBADSTR The encoded string was malformed and could not be expanded.
ARES_ENOMEM Memory was exhausted.
