I've re-implemented lastlogin, adding a parsable output format that makes it easy to scan for stale accounts. The differences are described below. Since others might find this useful, I've put the code up at ftp://orthanc.ab.ca/lyndon/freebsd/usr.sbin/lastlogin/. (If anyone wants to commit this, feel free.) ----- This is a re-implementation of lastlogin. It differs from the version included with FreeBSD 4.6 in the following ways. (Note: FL == "FreeBSD 4.6 lastlogin") * FL directly accessed /etc/passwd. It couldn't deal with NIS accounts. This version uses the getpw*() API to access the password database. * This version doesn't use stdio to access the lastlog file. * This version doesn't sort the results by uid. If you actually rely on that behaviour I would like to hear from you. * New -a flag makes lastlogin print information for users who have never logged in. * New -n flag prints (only) the last login time, in seconds since the epoch. For example: root 1031358466 lyndon 1032115401 The two fields are tab seperated. This format is designed to be easily parsed by other programs. * FL always displayed the contents of pw_name for the user name. If the password database contained multiple records with the same uid and unique names, the output from FL might not match the input. Let's say your password database contains these records: lyndon:*:100:100::: bob:*:200:200::: fred:*:100:100::: the output from "lastlogin bob fred" might display: lyndon ttyp3 :0.0 Sun Sep 15 15:15:17 2002 bob ttyp0 example.com Mon Dec 11 01:30:03 2000 In this version, the name from the command line is printed instead of the contents of pw_name.
