How do i open a Terminal with a command ready? [duplicate]

You can make a profile in Gnome terminal that automatically opens a script every time you open a Terminal.

Open a terminal and make a script in your home dir (ctrl-alt-t).

nano test

Enter your script, change the command and echo text to whatever you want

#!/bin/bash
echo "input syntax"
read command
#input command here instead of ls
ls "$command"
/bin/bash

save and exit. (ctrl-x, y)

Now open a terminal (ctrl-alt-t) Select Edit --> Profile prefferences.

Select run a custom command:

The next time you open a terminal it runs the script waiting for your input and finishes by opening bash.
