I have a variable that looks sort of like this:
msg="newton apple tree"
I want to assign each of these words into separate variables. This is easy to do in bash:
read a b c <<< $msg
Is there a compact, readable way to do this in POSIX shell?
To write idiomatic scripts, you can't just look at each individual syntax element and try to find a POSIX equivalent. That's like translating text by replacing each individual word with its entry in the dictionary.
The POSIX way of splitting a string known to have three words into three arguments, similar but not identical to read is:
var="newton apple tree"
set -f
set -- $var
set +f
a=$1 b=$2 c=$3
echo "$a was hit by an $b under a $c"
