hi. I'm a newbie in shell scripting as well as the *nix OS.
I just wanna ask about the symbol #! that I saw in many shell script examples. For instance,
[B]#![/B]/bin/bash . What does the #! symbol means?
What's the meaning of $1, $2, $3 symbols?
and what does the symbol ~ (like in
cd [B]~[/B][I]user_name[/I] ) means?
I'm sorry if this question sounds stupid and if my English is bad. English isn't my native languange.
