How to assign eval command as a parameter


Hi guys. I wonder how can i assign

Quote:
eval echo `shuf -n 1 randmsg.txt`
this command as a parameter. Apparently

Quote:
a=eval echo `shuf -n 1 randmsg.txt`
echo $a
This method did not work for me.. Thanks.

do you want $a to contain a random line from randmsg.txt?
i don't think you need eval for that, so
Code:
a="$(shuf -n 1 randmsg.txt)"
should suffice.

Hey thanks for the help. But when I try to send the parameter a as a message to a screen it gives this error on that screen

Quote:
a="$(shuf -n 1 randmsg.txt)"
screen -S screenname -X stuff $a^M
this prints a message on the screen that I want to send this message

Quote:
-X: stuff: no, one or two argument required
