hello. I'm fairly new to unix and have a few script writing questions for any experienced users. However, my computer is a mac so I need commands that will run in a macosx terminal.
ok:
q1) im writing a script where I want to get the history in the terminal and then write it to a specific text file. I'm not sure how to do it. I tried:
history | touch /dir/dir/dir/etc/filename

can anyone tell me why it didnt work/what would be the right command/commands.

q2)Im writing another script and I want the terminal to prompt the user for their password. I dont know how to collect user input or prompt them. Is it possible? All i can do is: echo 'password:'

but thats not an input prompt and the [ownername] command ready thing is just gonna pop back up once the script is done executing and they wont enter a password near my input prompt. how do i actually make a input/prompt thing?

q3)i have yet another script (lets call it script.sh). I want script.sh to execute when a user clicks on it rahter than them having to execute it with the ./ command in the terminal. How?


Well those are my questions. Hopefully someone can answer them. Thanks alot.
