I have two computers on a LAN both using Jaunty.
I "administer" both computers and have passwordless ssh access to both systems. I'm trying to write a script (or an alias) so that I can send notification bubbles to the computers remotely. Issuing the command
at a local terminal works like a charm - the notification bubble containing the message appears on the remote screen.
ssh -X user@host 'DISPLAY=:0 notify-send "TEST MESSAGE."'
Since the text "TEST MESSAGE." is just an example used here, and the message I will want to send will vary every time, "TEST MESSAGE." has to be made into a variable. If I create an alias on each system, such as
I can log in remotely, and at the remote prompt, simply enter and the quoted text, along with the quotes, is appended to the end of the aliased command.
alias chat='DISPLAY=:0 notify-send'
In trying to create an alias or a script - let's name it 'chat' in either case - that resides locally but uses SSH to execute a remote command, setting the variable is proving to be quite a headache. Since the structure should be the same as the above example, I have to pass along the double quotes as input. In trying to do so, I keep getting errors such as, "Invalid number of options," or, "No summary specified."
In using an alias, structured like so
I can send messages to the remote computer and have them appear on screen, but only if they are one or two words long - three words produces the "Invalid number of options" error.
alias chat='ssh user@host DISPLAY=:0 notify-send'
In using a script, I have to assign the "QUOTED MESSAGE" to a variable, otherwise I get the "No summary specified" error - the same error as if you went to a local prompt and typed without any text between the quotes.
In trying to nest the variable inside those quotes, like this
again produces errors. Exchanging the $1 variable for $@ causes the error to switch from one to the other.
ssh user@host DISPLAY=:0 notify-send "$1"
Can anyone offer me pointers as to how I would pass a quoted string as a variable into a simple one-liner like this?
