spectre Junior Member Registered: 03/05/02 Posts: 56 Loc: 192.168.128.80	Is there a command that I could use, as root, to message all the users connected to my system? I know that if you are going to perform a shutdown (shutdown -r now message), you can message all the users telling them "hey, I am going to shutdown now". But I simply just want to be able to send a message to everyone that says "hey, I am going to turn off the internet in 15 minutes". Yeah. I searched google, but it was all trash. Any help? Thanks. _________________________ http://www.javaspot.net

Only the super-user can write on the terminals of users who have chosen to deny messages or are using a program which automatically denies mes- sages. -g Send messages to users in this group. This option may be speci- fied multiple times, and any user in any of the specified groups will receive the message. SEE ALSO mesg(1), talk(1), write(1), shutdown(8) HISTORY A wall command appeared in Version 7 AT&T UNIX. 4th Berkeley Distribution June 6, 1993 4th Berkeley Distribution I didn't get it to work though. Another option is writing a simple perl or shell script, that does "who", gets and parses the output, and iterates through the users and sends them messages. I don't know Perl, so I can't write it. But I'm sure it wouldn't be hard at all. _________________________ Looking for great places to eat in Grand Junction?

pergesu Stoner Thugsta Registered: 03/14/02 Posts: 1134 Loc: Pimpin the Colorizzle	I got it too. On OS X you're supposed to specify a file on the command line. If you want it from the standard input, just hit enter, then type in all the text on one or several new lines, and hit ctrl+d. _________________________ Looking for great places to eat in Grand Junction?
