ISSUE A WARNING MESSAGE

[bennotech]

Hello All,
I would like a "warning message" issued on screen every time a certain command (rsh) is issued.
ie
rsh nodename date
"THIS IS A WARNING, BLAH, BLAH !"

I don't want to stop the command from being run.
Any ideas,
cheers
Benno

Install an alias (put it in /etc/profile for eveyone's use):

$ alias rsh='echo BlahBlah;rsh'
$ rsh rhost date
BlahBlah
host: name rhost NOT FOUND

Hello there,

you could write a script constantly running some kind of

tail -f | grep "command"

on the .sh_hist* files. And every time the grep finds the certain command you're looking for the command

wall "Warning Message"

is issued and put it into /etc/inittab...

But I'm not sure whether rsh commands generate an .sh_hist* entry or not. You'd have to issue rsh and have a look using

ls -ltr

and see if there's a fresh entry in one of the .sh_hist* files ...

Regards
Thomas

Better yet:

$ alias rsh='echo BlahBlah >&2;rsh'
$ rsh rhost date
BlahBlah
host: name rhost NOT FOUND
