   Welcome to Rust!
   
   This will download and install the official compiler for the Rust programming
   language, and its package manager, Cargo.
   
   It will add the cargo, rustc, rustup and other commands to Cargo's bin
   directory, located at:
   
     /root/.cargo/bin
   
   This path will then be added to your PATH environment variable by modifying the
   profile file located at:
   
     /root/.profile
   
   You can uninstall at any time with rustup self uninstall and these changes will
   be reverted.
   
   Current installation options:
   
      default host triple: x86_64-unknown-freebsd
        default toolchain: stable
     modify PATH variable: yes

   Rust is installed now. Great!
   
   To get started you need Cargo's bin directory ($HOME/.cargo/bin) in your PATH
   environment variable. Next time you log in this will be done automatically.
   
   To configure your current shell run source $HOME/.cargo/env
   

2. Set path $HOME/.cargo/bin

   $ vim /home/jail/jail-app/.cshrc
   set path = (/sbin /bin /usr/sbin /usr/bin /usr/local/sbin /usr/local/bin $HOME/bin $HOME/.cargo/bin)
   

   Reload
   $ source .cshrc

   Check version and default

   $ rustc --version
   rustc 1.37.0 (eae3437df 2019-08-13)
   
   $ rustup default
   stable (default)
   

   Rustup folder

   $ jexec jail-app
   $ cd /home/.rustup
