bash scripting capitalizing first letter or each word in a string


I am looking for a way to capitalize the first letter of each word that is in a string in bash. I know how to make a letter or string upper or lower case but I do not know how to break apart a string and do this just on the first character. Any help is much appreciated.

A="asdf asdf asdf";
for i in $A; do B=`echo "${i:0:1}" | tr a-z A-Z`${i:1}; echo -n "$B "; done

what is considered a "space" in bash is controled by the IFS variable.

I had better luck with this setup.
A="abcdef abcdef abcdef";
for i in $A; do B=`echo -n "${i:0:1}" | tr "[:lower:]" "[:upper:]"`; echo -n "${B}${i:1} "; done

Of course it's very simple to capitalize entire strings:
Code:
echo "string" | tr [:lower:] [:upper:]
in csh (freebsd), you have do silly things like escape characters:
Code:
echo "string" | tr \[\:lower\:\] \[\:upper\:\]
and instead of just
Code:
@bsd> A="string"
, you would
Code:
@bsd> set A="string"

bash4 should be able to do so using ${parameter^^pattern}

using an array
Code:
A="abcdef abcdef abcdef"
B=( $A )
echo "${B[@]^}"
Abcdef Abcdef Abcdef
