awk would be best.
Code:
awk -F: '$6 ~ /^\/home\/inst/ { $7="/bin/sh"; print; } {print}' /etc/passwd >copy-passwd

This isn't exactly what you asked for, but I think it's what you want. If you really don't want the other entries (the ones that have no /home/inst for a home dir), then remove the "{print}".
