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:
``` rust 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().unwrapor(("unknown".tostring(), 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:
bash
cargo run --example what_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.
