pshell
answers the question "Is my application running in a shell, and if so, which one?".
Example: you are installing something and want to make changes to the shell and you want to know what changes are required to which shell script.
Just a simple function that tells you whether the application is run from inside a shell:
use pshell;
fn main() {
// `find` returns the name of the shell in a string and the pid as a u32
let (sh, pid) = pshell::find().unwrap_or(("unknown".to_string(), 0));
println!("This application has been run from pid `{}`, which is a {} shell", pid, sh);
}
To try this out, and check it works OK on your OS/shell combination run the following from your shell:
cargo run --example what_shell
It is a small, simple crate that adds very little to your application size for discovering what shell this is running under by inspecting the name of the parent processes against a limited list of known shells.
You want an all-singing, all-dancing crate that identifies any knowns shell.
I have created a list of shells where this could be run from, it is not exhaustive, if your shell is not supported, feel free to raise an issue or a PR.
