I have never seen this anywhere in my search I am making a script to see if I can send a string variable to notify-send so far
$MESSAGE='Hello world!'
notify-send "`$MESSAGE`" -t 1
will trow
Hello command not found
and
notify-send $MESSAGE -t 1
sends a too many argument error
so is there a way to do that?
Try this:
MESSAGE='Hello world!'
notify-send "$MESSAGE" -t 1
We declare a variable using NAME=VALUE in bash. There's no $ sign before the variable name. Then you enclose variable value obtained by using $ character using ". The ` character is used as a command substitution, same as $(...).When you write "`$MESSAGE`", you tell you bash to execute command named Hello with argument world!. As such command does not exists, your bash returns Hello command not found.
