} You can do it without an auxiliary process, but with a local variable,

} read -A line <$1
} field=$line[4]
If you're already using a local throwaway,
read x x x field x <$1
Or you can use the omnipresent local argv so you needn't declare it:
(){ read -A argv; field=$4 } < $1
} You might want "read -qe" if the file contains backslashes.
I believe -q is a typo for -r there.
