Assuming e.txt is actually /etc/passwd, you should actually use getent passwd instead of parsing the file since user account information may be stored in multiple locations specified in /etc/nsswitch.conf such as LDAP.
getent passwd | awk -F ':' '$6 ~ "^/home"'
Note that the print statement is implied when the condition is true. That will print the whole line, though. This will print only the user name:
getent passwd | awk -F ':' '$6 ~ "^/home" {print $1}'
