Number of times a user is "connected"?
hi i wish make a shell to look for the number of times a user is connected then makes a "whatch dog" by crontab to handle this
i could do it through ps-fedal| grep user_name | wc-l ... etc.
but others suggested me another algorithm
and thought to use w, or finger, or who
but it have a problem
if I try (as root) open a command interpreter and use
su username
none of the above commands recognize me as the new user where I am, It still recognize as root
how could I fix this? or which other command allows me to see what actions or process a user doing on the machine?
.
by the way im from colombia and im an Unix's (CentOS 5) novice user
thank you very much for your comprention and attention

Possible values are: left-thumb, left-index-finger, left-middle-finger, left-ring-finger, left-little-finger, right-thumb, right-index-finger, right- middle-finger, right-ring-finger, right-little-finger. The default is automatic, selecting the first available finger for swipe devices, or all the enrolled fingers, for press devices. TEST APPLICATIONS
fprintd-enroll Will enroll the user's right index finger into the database. fprintd-list Will list the user's enrolled fingerprints. fprintd-verify Will enroll the user's right index finger into the database. fprintd-enroll Will enroll the user's right index finger into the database. AUTHOR
