Of course, you have to supply the actual encrypted password, either directly, eg

awk -F':' -v OFS=':' '/^root/{$2="%@/&-:()"}1' /etc/shadow |grep root

or with a variable, eg

awk -F':' -v OFS=':' -v pw='%@/&-:()' '/^root/{$2=pw}1' /etc/shadow

Replace the "%@/&-:()" string with the actual encrypted password.
