Grep on console output
Hellos!
I want to have a unix script that will run grep on the console output. Here is what my script does:
1. Telnet into a remote server (I have done this part successfully)
2. On successful login, the remote server displays outputs information on the console. I need to run grep on that console output (need help with this)
So, I need a script to run grep on the output appearing on the console.
Any thoughts??
Thanks,
Puneet

console.handlers
console.handlers(5) System Administrator's Manual console.handlers(5)
NAME
console.handlers - file specifying handlers of console lock and unlock events
DESCRIPTION
/etc/security/console.handlers determines which programs will be run when an user obtains the console lock at login time, and when the user
loses it on log out. It is read by the pam_console module.
The format is:
handler-filename lock|unlock [flag ...]
Where handler-filename is a name of the executable to be run, lock or unlock specifies on which event it should be run, and flags specify
how should pam_console call it.
Additionally there should be a line which specifies glob patterns of console devices.
The format of this line is: console-name consoledevs regex [regex ...]
Where console-name is a name of the console class - currently ignored - and regexes are regular expression patterns which specify the name
of the tty device. Only the first such line is consulted.
FLAGS
logfail
The pam_console module should log error to the system log if the return value of the handler is not zero or if the handler can not
be executed.
wait The pam_console should wait for the handler to exit before continuing.
setuid The handler should be executed with uid/gid of the user which obtained the console lock.
tty The handler will get a tty name as obtained from PAM as a parameter.
user The handler will get an user name as obtained from PAM as a parameter.
Anything else will be added directly as a parameter to the handler executable.
